Perchloroethylene, also known as perchloroethylene, is an important organic chlorine product. It is mainly used in industry as organic solvent, dry cleaning agent, desulfurizer, fabric finishing agent, metal detergent, fatty extractant, organic synthesis and heat transfer medium, medical use as insect repellent, and intermediate in refrigerant.
Perchloroethylene is widely used, mainly as a metal degreasing solvent and also as an anthelmintic drug. Perchloroethylene can be used as a fatty extractant, fire extinguishing agent, smoke screen agent, etc., and can also be used to synthesize trichloroethylene and fluorine-containing organic compounds; Widely used as a dry cleaning agent for natural and synthetic fibers. It is also used as a degreasing detergent and general solvent for metals, organic synthesis intermediates, etc.; Used as a standard material for chromatographic analysis; Insect repellent and fat extractants used for adhesives.
Raw material grade tetrachloroethylene can be used as a raw material for the production of CFC-113 and hexachloroethane, and can also be used as a general organic solvent.
Fluorocarbon-grade tetrachloroethylene is widely used as a raw material for new refrigerants in HCFC-123, HCFC-124,HCFC-125、HCFC-134aproduction; the above refrigerants are currently replacingR22The main product of R502 has no destructive effect on the ozone layer.
Catalyst grade tetrachloroethylene can be used in petrochemical isomerization and catalytic reforming units, playing an important auxiliary catalytic role in the petrochemical aromatics industry
Cleaning grade tetrachloroethylene can be used in dry cleaning of clothes, metal degreasing, electronic cleaning, and can also be used as a fat extractant, fur degreasing agent, and an extractant for natural and synthetic fibers.
