Application:Catalyst grade PCE is extensively used in the regeneration of oil-refining catalysts. It is an important auxiliary catalyst in the aromatics field of petrochemical industry; Fluorocarbon grade PCE is extensively used as an intermediate in the manufacture of new refrigerants, namely, HCFC-125 and HCFC-134a (these refrigerants are non ozone-depleting and the main substitutes for R22 and R502); Raw-material grade PCE is extensively used as an intermediate in the manufacture of CFC-113, hexachloroethane and pesticides. It is also used as general organic solvent; Cleaning grade PCE is extensively used in dry cleaning, metal degreasing and electronic cleaning, It is also used as fat extract, fur grease remover and extract for both natural and synthetic fibers.
Physical and chemical properties:Under normal temperature and pressure, colorless and transparent liquid with the scent similar to chloroform; Melting point is -22.2℃, Boiling point is 121.2℃. Density is 1.620-1.628 g/cm3. Insoluble in water. Soluble in various organic solvents such as ethanol and ether.
Storage & transportation:The product is packed in new steel drums or tanks(or tank cars). Store only in cool and dry area provided with exhaust ventilation. Keep the drums tightly sealed, Drums, if opened, should be sealed again and keep in up-right position to avoid leakage. The transport vehicle should carry suitable fire extinguishers and leakage-handing equipments, It is to comply with the local governmental regulations of railway and road transportation concerning hazardous cargos.
Packing specifications:210L/300kg galvanized/ blue painted drums, tanks.
