APPLICATIONS

The largest usage of this compound is for the production of vinyl chloride monomer, which is used to produce polyvinyl chloride (PVC). It can also be used as a solvent, fumigant, degreaser, paint remover and intermediate for other organic compounds (methyl chloroform, perchloroehtylene and ethylene amines, polyvinyl chloride, sulfide compounds, acetyl cellulose, trichloroethylene, vinylidene chloride and trichloroethane). It is also used as an antiknock additive in leaded fuels.
