Overview
ASTM D5471-23: Standard Specification for O-Xylene 980 defines the requirements for a high-purity grade of ortho-xylene known as O-Xylene 980. Issued by ASTM International, this standard provides essential quality characteristics and test procedures to ensure consistency and safety in both production and industrial applications. The specification details required purity levels, allowable impurities, appearance, color, and other critical properties for O-Xylene 980, facilitating reliable and safe handling throughout the supply chain.
Key Topics
ASTM D5471-23 addresses several key quality parameters for O-Xylene 980:
- Purity: Requires a minimum purity of 98.0% by weight, confirming the material’s suitability for high-purity applications.
- Impurities: Establishes maximum allowable concentrations for:
- Non-aromatic hydrocarbons (0.5%)
- p-xylene plus m-xylene (1.3%)
- C9 and heavier aromatics (0.8%)
- Cumene (0.5%)
- Bromine Index: Limits reactivity with a maximum bromine index of 100 mg/100 g.
- Appearance and Color: Specifies the product must be a clear liquid, free of sediment and haze, with a color not exceeding 10 on the platinum-cobalt (Pt-Co) scale.
- Distillation Range: Defines a controlled distillation range to ensure consistency and safety in downstream processing.
- Testing and Sampling: Outlines standardized test methods and practices for determining conformity, referencing ASTM methods for reliable and reproducible results.
Applications
O-Xylene 980 produced under ASTM D5471-23 finds use in a variety of industries due to its high purity and controlled properties:
- Chemical Manufacturing: Serves as a feedstock in the production of phthalic anhydride, plasticizers, and resins.
- Solvent Applications: Used in formulation of paints, coatings, and adhesives where high-purity aromatics are required.
- Laboratory Standards: Provides a reliable reference material for analytical and quality control laboratories.
- Specialty Processes: Selected for industrial processes that demand low levels of impurities to prevent contamination or ensure product quality.
- Regulated Environments: Essential for industries where conformity to regulatory or international safety standards for aromatic hydrocarbons is necessary.
