Overview
ASTM D5871-19: Standard Specification for Benzene for Cyclohexane Feedstock establishes the requirements and test methods for benzene used specifically as feedstock in cyclohexane production. Developed by ASTM International, this standard ensures consistency, safety, and high purity in benzene supplied for industrial processes requiring cyclohexane, such as in the manufacture of nylon, resins, and solvents. The specification is widely recognized for ensuring quality control and compliance in industrial supply chains, utilizing internationally accepted measurement and safety practices.
Key Topics
Scope and Purpose
The document outlines the minimum quality standards that benzene must meet for it to be used as cyclohexane feedstock. It includes instructions for rounding test results, using SI units as standard, and references to relevant safety regulations.Required Properties
Benzene intended for cyclohexane feedstock must conform to strict purity and composition requirements. Key properties include:- Benzene content (minimum value required)
- Sulfur and thiophene content (maximum allowed amounts)
- Limited presence of impurities such as toluene, methylcyclohexane, methylcyclopentane, and n-hexane
- Acid wash color, visual appearance, and platinum-cobalt color value
- Solidification point and optional water content
Testing Methods
Compliance is confirmed using referenced ASTM test methods such as:- Gas Chromatography
- Acid wash and color determination
- Solidification point testing
- Water content assessment (when specified)
Safety and Compliance
The standard emphasizes adherence to Occupational Safety and Health Administration (OSHA) regulations and using current Safety Data Sheets for all materials. It complies with World Trade Organization principles for the development of international standards.
Applications
Industrial Production of Cyclohexane
The primary application of this specification is in facilities where benzene is converted to cyclohexane, a key precursor in the production of nylon and other synthetic fibers.Chemical Manufacturing
Manufacturers and suppliers of high-purity chemicals utilize this standard to meet quality requirements and maintain consistency in raw material feedstocks.Quality Assurance and Supply Chain
Procurement specialists and quality assurance teams reference ASTM D5871-19 to verify product conformance and support regulatory compliance in the acquisition and delivery of benzene for industrial end-users.Safety and Environmental Compliance
Environmental health and safety managers use the standard to align operational practices with regulatory requirements for handling and processing benzene and related chemicals.
