Standard Test Method for Determining Chloride in Aromatic Hydrocarbons and Related Chemicals by Microcoulometry

SIGNIFICANCE AND USE
5.1 Organic as well as inorganic chlorine compounds can prove harmful to equipment and reactions in processes involving hydrocarbons.  
5.2 Maximum chloride levels are often specified for process streams and for hydrocarbon products.  
5.3 Organic chloride species are potentially damaging to refinery processes. Hydrochloric acid can be produced in hydrotreating or reforming reactors and this acid accumulates in condensing regions of the refinery.
SCOPE
1.1 This test method covers the determination of organic chloride in aromatic hydrocarbons, their derivatives, and related chemicals.  
1.2 This test method is applicable to samples with chloride concentrations to 25 mg/kg. The limit of detection (LOD) is 0.2 mg/kg and the limit of quantitation (LOQ) is 0.7 mg/kg. With careful analytical technique or the measurement of replicates, or both, this method can be used to successfully analyze concentrations below the LOD.
Note 1: The maximum is the highest concentration from the interlaboratory study and the LOD and LOQ were calculated from Performance Testing Program (PTP) data. See Table 1.  
1.3 This test method is preferred over Test Method D5194 for products, such as styrene, that are polymerized by the sodium biphenyl reagent.  
1.4 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29.  
1.5 Organic chloride values of samples containing inorganic chlorides will be biased high due to partial recovery of inorganic species during combustion. Interference from inorganic species can be reduced by water washing the sample before analysis. This does not apply to water soluble samples.  
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see 7.3 and Section 9.  
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Water Using Volumetric Karl Fischer Titration

SIGNIFICANCE AND USE
4.1 Titration techniques using KF reagent are one of the most widely used for the determination of water.  
4.2 Although the volumetric KF titration can determine low levels of water, it is generally accepted that coulometric KF titrations (see Test Method E1064) are more accurate for routine determination of very low levels of water. As a general rule, if samples routinely contain water concentrations of 500 mg/kg or less, the coulometric technique should be considered.  
4.3 Applications can be subdivided into two sections: (1) organic and inorganic compounds, in which water may be determined directly, and (2) compounds, in which water cannot be determined directly, but in which interferences may be eliminated by suitable chemical reactions or modifications of the procedure. Further discussion of interferences is included in Section 5 and Appendix X2.  
4.4 Water can be determined directly in the presence of the following types of compounds:    
Organic Compounds  
Acetals  
Ethers  
Acids (Note 1)  
Halides  
Acyl halides  
Hydrocarbons (saturated and unsaturated)  
Alcohols  
Ketones, stable (Note 4)  
Aldehydes, stable (Note 2)  
Nitriles  
Amides  
Orthoesters  
Amines, weak (Note 3)  
Peroxides (hydro, dialkyl)  
Anhydrides  
Sulfides  
Disulfides  
Thiocyanates  
Esters  
Thioesters  
Inorganic Compounds  
Acids (Note 5)  
Cupric oxide  
Acid oxides (Note 6)  
Desiccants  
Aluminum oxides  
Hydrazine sulfate  
Anhydrides  
Salts of organic and inorganic acids (Note 6)  
Barium dioxide  
Calcium carbonate  
Note 1: Some acids, such as formic, acetic, and adipic acid, are slowly esterified. For high accuracy with pyridine-based reagents, use 30 % to 50 % pyridine in methanol as the solvent. When using pyridine-free reagents, commercially available buffer solutions can be added to the sample prior to titration. With formic acid, it may be necessary to use methanol-free solvents and titrants (1).4
N...
SCOPE
1.1 This test method is intended as a general guide for the application of the volumetric Karl Fischer (KF) titration for determining free water and water of hydration in most solid or liquid organic and inorganic compounds. This test method is designed for use with automatic titration systems capable of determining the KF titration end point potentiometrically; however, a manual titration method for determining the end point visually is included as Appendix X1. Samples that are gaseous at room temperature are not covered (see Appendix X4). This test method covers the use of both pyridine and pyridine-free KF reagents for determining water by the volumetric titration. Determination of water using KF coulometric titration is not discussed. By proper choice of the sample size, KF reagent concentration and apparatus, this test method is suitable for measurement of water over a wide concentration range, that is, parts per million to pure water.  
1.2 The values stated in SI units are to be regarded as standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific warnings are given in 3.1 and 7.3.3.  
1.4 Review the current Safety Data Sheets (SDS) for detailed information concerning toxicity, first aid procedures, and safety precautions for chemicals used in this test procedure.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Hydroxyl Groups Using Reaction with p-Toluenesulfonyl Isocyanate (TSI) and Potentiometric Titration with Tetrabutylammonium Hydroxide

SIGNIFICANCE AND USE
5.1 Hydroxyl is an important functional group and knowledge of its content is required in many intermediate and end use applications. This test method is for the determination of primary and secondary hydroxyl groups and can be used for the assay of compounds containing them.  
5.2 This test method has the following advantages over other hydroxyl number methods: It is rapid (10 min), pyridine-free, ambient temperature, small sample size, applicable to extremely low hydroxyl numbers (
SCOPE
1.1 This test method covers the determination of hydroxyl groups attached to primary and secondary carbon atoms in aliphatic and cyclic compounds and phenols from 0.5 to 367 hydroxyl number. It is not suitable for determination of hydroxyl groups attached to tertiary carbon atoms. This test method is applicable to polyacetals, temperature sensitive materials, high solids polymer polyols, and rigid polyols. Other available test methods listed in Note 1 are not suitable for many of the sample types listed above.  
1.1.1 This test method is currently recommended for neutral refined products. Successful application has been made, however, to some in-process samples that contain an excess of acidic species. Proper validation must be performed, of course, to show that the acidic species either does not interfere, or that the acidic species interference has been obviated.
Note 1: Other methods for determination of hydroxyl groups are given in Test Methods D817, D871, D4252, D4273, D4274, E222, E326, and E335.  
1.2 The Limit of Detection (LOD) is 0.18 units and the Limit of Quantitation (LOQ) is 0.59 units. Unit = hydroxyl number (OH#).
Note 2: LOD and LOQ were calculated using Standard deviations from 14.1.2.1.  
1.3 Review the current appropriate Safety Data Sheets (SDS) for detailed information concerning toxicity, first aid procedures, and safety precautions.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 The following applies for the purposes of determining the conformance of the test results using this test method to applicable specifications. Results shall be rounded off in accordance with the rounding-off method of Practice E29.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated, with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazards see Section 9.

Standard Test Method for Iron Content of Bisphenol A (4,4′ - Isopropylidenediphenol)

SIGNIFICANCE AND USE
5.1 Iron may increase the color of bisphenol A and affect other properties of end-use products.  
5.2 High purity bisphenol A typically has less than 1 mg/kg of iron.
SCOPE
1.1 This test method covers the determination of the iron content of bisphenol A (4,4′-isopropylidenediphenol).  
1.2 This test method has a lower detection limit of 0.1 mg/kg, and an upper limit of 10 mg/kg of iron in bisphenol A. If the iron (Fe) content is higher, it may be necessary to dilute the sample. A longer path length cell can also be used for better accuracy at lower Fe levels, as well as calibration within the range expected (for example, 0 mg/kg to 1 mg/kg versus 0 mg/kg to 10 mg/kg for samples expected to be in the 0 mg/kg to 1 mg/kg range.  
1.3 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limits prior to use.  For a specific hazard statement, see Section 9.

Standard Test Methods for Hydroxyl Groups Using Acetic Anhydride Acetylation

SIGNIFICANCE AND USE
4.1 Hydroxyl is an important functional group, and knowledge of its content is required in many intermediate and end use applications. The test methods described herein are for the determination of primary and secondary hydroxyl groups and can be used for the assay of compounds containing them.
SCOPE
1.1 These test methods cover the determination of hydroxyl groups attached to primary and secondary carbon atoms in aliphatic and alicyclic compounds and phenols.  
1.2 Three test methods are given as follows:    
Sections  
Test Method A (Pressure Bottle Method)  
8 – 14    
Test Method B (Reflux Method)  
16 – 22    
Test Method C (Perchloric Acid Catalyzed Method)  
24 – 30  
1.2.1 Test Method A is recommended for general use. Test Method B is included to give a standard procedure for the method that has been used widely. Test Method C is recommended when the results are required in a minimum period of time or where ambient temperature for the reaction is desired.  
1.2.2 The results obtained using Test Methods A and B will be essentially the same, but the results obtained using Test Method C will be higher (up to approximately 4 % relative) than those obtained using the other two methods.  
1.2.3 Statements on precision are included with each test method. The precision of Test Methods A and C is consistent over a wide range of hydroxyl content (tested over hydroxyl number range of 250 to 1600), whereas Test Method B is less precise at the higher hydroxyl content level than it is at the lower hydroxyl content level. In general, Test Method A is approximately two-fold as precise as Test Method C. Test Method B has approximately the same precision as Test Method C at the lower hydroxyl content level but poorer precision at the higher hydroxyl content level.  
1.2.4 The interferences are essentially the same for the three methods. Some compounds can be analyzed using Test Methods A or B but not using Test Method C because of interfering reactions of the strong acid catalyst with the compound being analyzed or the acetate product formed in the determination. However, because of its increased reactivity, Test Method C is applicable for determination of some compounds, particularly sterically hindered secondary alcohols, which react too slowly or not at all in Test Methods A and B.
Note 1: Other methods for determination of hydroxyl groups are given in Test Methods D1957, D2195, E326, E335, and E567.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded in accordance with the rounding off methods of Practice E29.  
1.5 Review the current appropriate Safety Data Sheets (SDS) for detailed information concerning toxicity, first aid procedures, and safety precautions.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Section 7.

ASTM
ASTM D8266-19(Test Method)
Standard Test Method for Analysis of Bisphenol A (4,4`-Isopropylidenediphenol) by High Performance Liquid Chromatography

SIGNIFICANCE AND USE
4.1 Bisphenol A is used for production of polycarbonate or epoxy resin. The presence of impurities in bisphenol A is undesirable because they may slow down the polymerization and be impurities in the final product.  
4.2 Determination of the trace impurities, such as isomer of bisphenol A and the unreacted raw material, is often required. This test method is suitable for setting specifications and for using as an internal quality control where these products are produced or used.  
4.3 Purity is commonly reported by subtracting the determined expected impurities and water from 100 %. However, a HPLC analysis cannot determine absolute purity if unknown components are contained within the material being examined.
SCOPE
1.1 This test method covers the determination of trace impurities in bisphenol A (4,4′-Isopropylidenediphenol) by reverse-phase gradient high performance liquid chromatography (HPLC). It is generally meant for the analysis of bisphenol A of 99.5 % or greater.  
1.2 This method is applicable to bisphenol A samples containing impurity concentration between 2 and 400 mg/kg. Users of this method believe it is linear over a wider range.  
1.3 In determining the conformance of the test results using this method to applicable specification, results shall be rounded off in accordance with the rounding-off method of Practice E29.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see Section 8.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D891-18(Test Method)
Standard Test Methods for Specific Gravity, Apparent, of Liquid Industrial Chemicals

SIGNIFICANCE AND USE
4.1 Specific gravity, apparent, may be used as a qualitative test in establishing the identity of a chemical. It may be used to calculate the volume occupied by a product whose weight is known, or to calculate the weight of a product from its volume. It may be used to determine the composition of binary mixtures of pure chemicals. In the case of most refined industrial chemicals specific gravity, apparent, is of minimal value in defining quality, although it may detect gross contamination.  
4.2 Of the two test methods described, the pycnometer method (Test Method B, 1.1.2) is the most accurate and precise. For this reason it is the preferred method in case of disputes. The hydrometer method (Test Method A, 1.1.1) is the least accurate and precise, but it is also the simplest and fastest to perform and is often entirely satisfactory for many purposes. If the sample is too viscous to permit the hydrometer to float freely, the pycnometer test method should be used.
SCOPE
1.1 These test methods cover the determination of the specific gravity, apparent, of liquid industrial chemicals. Two test methods are covered as follows:  
1.1.1 Test Method A, specific gravity, apparent, by means of a hydrometer.  
1.1.2 Test Method B, specific gravity, apparent, by means of a pycnometer.  
Note 1: Test Method D4052 describes an instrumental procedure.  
1.2 In common usage the term specific gravity, apparent, is understood to mean specific gravity.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in these test methods with the exception of Fahrenheit (°F) in 5.1 as an example of a possible industrial specification unit.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Sections 8 and 16.
