(Specification)Standard Specification for Fluorocarbon Feedstock Grade Chloroform
Standard Specification for Fluorocarbon Feedstock Grade Chloroform
ABSTRACT
This specification covers the requirements for trichloromethane chloroform intended for use as fluorocarbon feedstock. The fluorocarbon feedstock grade chloroform shall have a clear appearance, free of sediments and suspended matters. Tests shall be conducted to determine conformance to the following properties: water content, non-volatile residue content, color in the platinum-cobalt scale, free halogen content, acidity as HCl, dichloroethane content, carbon tetrachloride content, methylene chloride content, dichloroethylene content, and wt% of the assay. Products shall be packaged and labeled in accordance with DOT regulations, state and local regulations, and OSHA regulations.
SCOPE
1.1 This specification specifies chloroform (trichloromethane) that is suitable for use as feedstock for fluorocarbons.
1.2 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.
1.3 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 D7509-09(2021), Standard Specification for Fluorocarbon Feedstock Grade Chloroform, establishes the quality, purity, and handling requirements for chloroform (trichloromethane) used as feedstock in fluorocarbon production. Developed by ASTM International, this standard ensures that chloroform supplied for industrial purposes meets strict criteria for chemical composition, appearance, and packaging. Adherence to this specification helps users comply with regulatory standards, improve safety, and guarantee the reliable performance of chloroform in downstream chemical manufacturing processes.
Key Topics
- Product Purity Requirements: The standard includes specifications for appearance (clear, free from sediment and suspended matter) and key analytes such as water content, non-volatile residue, color (measured on the platinum-cobalt scale), free halogens, acidity (as HCl), and a range of potential impurities like 1,1-dichloroethane, carbon tetrachloride, methylene chloride, and 1,2-dichloroethylene.
- Minimum Assay Value: Specifies a minimum purity of 99.95% by weight for chloroform intended as fluorocarbon feedstock.
- Test Methods: References standardized ASTM test methods for measurement of each property, ensuring consistent and reliable assessment across suppliers and users.
- Packaging and Labeling: Mandates that all packaging and labeling adhere to Department of Transportation (DOT), Occupational Safety and Health Administration (OSHA), federal, state, and local regulations.
- International Alignment: Developed in accordance with internationally recognized principles, ensuring compatibility with global trade and regulatory environments.
Applications
The primary use of fluorocarbon feedstock grade chloroform as defined by ASTM D7509-09(2021) is in the chemical synthesis of fluorocarbons. These compounds are essential in manufacturing:
- Refrigerants
- Blowing agents for insulation foams
- Solvents and intermediates in the chemical industry
By meeting the specifications in ASTM D7509-09(2021), producers and users can:
- Ensure product quality, purity, and safety
- Prevent process interruptions or product failures due to contamination
- Facilitate international trade by aligning with widely recognized test methods and regulatory requirements
Additionally, consistent quality and regulatory-compliant packaging help manage the risks associated with handling volatile and potentially hazardous substances like chloroform.
