Solvent Uses & Facts
Dichloromethane, or methylene chloride, is widely used in paint removers and chemical processing operations, as well as in the aerosols and adhesive formulations, and as a cleaning agent for fabricated metal parts. It is also used to decaffeinate coffee and tea and for the extraction of hops. Dichloromethane is used as a chemical intermediate in the production of hydrofluorcarbon (HFC) 32 which is used in refrigerant blends developed to replace substances with higher global warming potential.
Perchloroethylene (also known as perc or tetrachloroethylene) is used by approximately 70 percent of commercial dry cleaners due to its non-flammability and relatively low toxicity. It is also used for brake cleaning and for vapor degreasing of metal parts.
Trichloroethylene (also known as TCE) is widely used as a metal degreaser and a chemical process intermediate. It is also used as a solvent in the metal processing, electronics, printing, pulp and paper, and textile industries. Both trichloroethylene and perchloroethylene are used as chemical intermediates in the production of HFC-134a.
