Standard Specification for Dibutyl Phthalate
ABSTRACT
This specification establishes the properties and requirements of 99 % grade dibutyl phthalate. The material shall be sampled and tested suitably, and shall conform to properties as to apparent specific gravity, color (Pt-Co scale), odor, water content, acidity (free acid as phthalic acid), and ester value.
SCOPE
1.1 This specification covers dibutyl phthalate (99 % grade).
1.2 The following applies to all specified limits in this standard: for purposes of determining conformance with this standard, an observed value or a calculated value shall be rounded off “to the nearest unit” in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E29.
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 For specific hazard information and guidance, see the supplier's Material Safety Data Sheet for materials listed in this specification.
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.

Overview
ASTM D608-05(2019) - Standard Specification for Dibutyl Phthalate outlines the minimum requirements and properties for 99% grade dibutyl phthalate. Issued by ASTM International, this standard ensures consistency and quality for dibutyl phthalate, a widely used chemical plasticizer and industrial solvent. The specification details sampling, testing, and packaging methods to maintain safety, regulatory compliance, and product performance.
Dibutyl phthalate produced to this standard is assessed through a defined range of physical and chemical properties, including apparent specific gravity, color (using the Pt-Co scale), odor, water content, acidity (as free phthalic acid), and ester content.
Key Topics
Specification Scope
- Applies exclusively to 99% grade dibutyl phthalate.
- The use of SI units is mandatory for all measurements.
- Rounding of test results must follow ASTM Practice E29.
- Users must consult suppliers’ Material Safety Data Sheets for specific hazard information.
Critical Properties and Testing
- Apparent Specific Gravity: Checked at 20°C or 25°C, ensuring material identity and purity.
- Color Measurement: Determined by the Pt-Co (Platinum-Cobalt) scale, confirming the absence of unwanted coloration.
- Odor: The product should have a non-residual odor, ensuring suitability for sensitive applications.
- Water Content: Strict maximum limit up to 0.2% by weight to avoid process or material interference.
- Acidity: Very low free acidity as phthalic acid, capped at 0.01% by weight, minimizing reactivity concerns.
- Ester Value: Must not be less than 99.0%, confirming high purity and usability as a plasticizer or solvent.
Sampling and Testing Methods
- Sampling must comply with ASTM Practice E300.
- Test methods referenced in the standard include ASTM D4052 for density, D1209 for color, D1296 for odor, D1364 for water content, D1613 for acidity, and D1617 for ester value.
Applications
Adherence to ASTM D608-05(2019) provides assurance of dibutyl phthalate’s quality and consistency, making it suitable for:
- Plastics and Polymer Manufacturing: Used as a primary plasticizer in PVC and other resins, ensuring flexibility and durability.
- Paint and Coating Formulations: Acts as a film-forming aid and solvent, influencing finish quality and processability.
- Adhesives and Sealants: Provides stable viscosity and improved workability.
- Industrial Chemical Processing: Used as an intermediate, its purity ensures reliable further synthesis.
By using dibutyl phthalate conforming to this standard, manufacturers uphold product safety, regulatory compliance, and end-user satisfaction.
