Overview

ASTM D843-19: Standard Specification for Nitration Grade Xylene defines the required properties and quality standards for nitration grade xylene. Developed by ASTM International under the direction of Committee D16, this standard ensures consistency, reliability, and safety in the production and application of xylene used for chemical processes, especially nitration.

This specification establishes requirements for chemical composition, appearance, performance tests, and conformance verification for nitration grade xylene. The document also references related test methods, safety considerations, and internationally recognized measurement and compliance protocols.

Key Topics

• Quality Requirements
  Nitration grade xylene must meet defined limits for nonaromatic hydrocarbons, acid wash color, copper corrosion, color, and physical appearance. Specific temperature ranges for distillation, as well as initial boiling point and dry point, are also prescribed.

• Testing Methods
  Several ASTM test methods are referenced for conformance:

  • Nonaromatic hydrocarbons: ASTM D6563 or D7504
  • Acid wash color: ASTM D848
  • Copper corrosion: ASTM D849
  • Appearance: ASTM E2680
  • Color (Pt/Co scale): ASTM D5386 or D8005
  • Distillation characteristics: ASTM D850

• Sampling
  The sampling process must be performed in accordance with ASTM D3437, ensuring the representativeness and integrity of samples for laboratory analysis.

• Conformance and Rounding
  All specified limits require rounding to the nearest unit, following ASTM E29, to ensure uniformity in results and interpretations.

• Safety and Regulatory Guidance
  Compliance with OSHA regulations and local safety data requirements is emphasized. Users are instructed to consult relevant Safety Data Sheets (SDS) and applicable legislation to ensure safe handling and use of xylene.

Applications

Nitration grade xylene is a highly purified aromatic hydrocarbon widely used in industrial and laboratory environments. Its main applications include:

• Chemical Manufacturing
  Utilized as a raw material or intermediate in the synthesis of pharmaceuticals, agrochemicals, dyes, and resins through nitration and other chemical reactions.

• Solvent in Industrial Processes
  Applied in processes where high purity and specific boiling range are critical, such as in coatings, paints, adhesives, and inks manufacturing.

• Laboratory Use
  Serves as a standard solvent or reference material for research, quality control testing, and chemical synthesis.

Ensuring compliance with ASTM D843-19 safeguards process reliability, product consistency, and safety for end users and manufacturing staff.

Related Standards

For accurate implementation and verification, ASTM D843-19 references several associated standards:

• ASTM D848: Acid Wash Color of Industrial Aromatic Hydrocarbons
• ASTM D849: Copper Strip Corrosion by Industrial Aromatic Hydrocarbons
• ASTM D850: Distillation of Industrial Aromatic Hydrocarbons
• ASTM D3437: Sampling and Handling Liquid Cyclic Products
• ASTM D5386/D8005: Color Measurement of Liquids
• ASTM D7504: Trace Impurities Analysis in Monocyclic Aromatic Hydrocarbons
• ASTM E29: Use of Significant Digits in Test Data
• OSHA Regulations: 29 CFR 1910.1000 and 1910.1200 (Hazardous substances and chemical safety)

These referenced methods ensure the integrity, safety, and performance of nitration grade xylene, supporting industries that require precise, high-purity aromatic solvents.
