The manufacture, distribution, and consumption of 1,2-dichloroethane, a chlorinated hydrocarbon intermediate produced by direct chlorination or oxychlorination of ethylene, are all included in the global ecosystem known as the ethylene dichloride (EDC) market. EDC is used as a solvent in organic synthesis and extraction processes, but it is primarily used as a precursor for vinyl chloride monomer (VCM) in the production of polyvinyl chloride (PVC) resin, which accounts for more than 90% of demand.
