1,2-Dichloroethane CAS 107-06-2

FAQ - Technical & Supply Chain

• Q:

  Is 1,2-Dichloroethane the same chemical as Ethylidene Chloride?

  A: No. 1,2-Dichloroethane, CAS 107-06-2, is correctly called Ethylene Dichloride or EDC. Ethylidene Chloride usually means 1,1-Dichloroethane, CAS 75-34-3. Use the CAS number to distinguish the isomers.
• Q:

  What is 1,2-Dichloroethane used for?

  A: It is used mainly as an intermediate for vinyl chloride monomer and PVC production, and in controlled industrial applications as a chlorinated solvent or process agent. The required purity depends on the downstream process.
• Q:

  What distinguishes an industrial 1,2-Dichloroethane grade?

  A: Define the intended process and limits for EDC purity, low- and high-boiling impurities, water, color, acidity, alkalinity, nonvolatile residue, soluble iron and other process-specific contaminants. Supplier methods should match the intended use.
• Q:

  What information is needed before arranging 1,2-Dichloroethane delivery?

  A: Provide quantity, destination, packaging or bulk-delivery mode, consignee handling capability and any import-permit requirements. EDC is a regulated hazardous liquid, so also confirm the UN number, class, packaging code and transport mode.
• Q:

  What physical properties identify 1,2-Dichloroethane?

  A: 1,2-Dichloroethane is a colorless chlorinated liquid with a melting point around -35 C, boiling point around 83 C and density about 1.25-1.256 g/mL. It has a low flash point and forms heavier-than-air vapor, so flammability and ventilation must be managed.
