English title : Tetrachloroethylene; Perchlorethylene; tetrachloro - Ethene; 1,1,2,2 - tetrachlorethylene; AI3 - 01860
traits Description : transparent colorless liquid, with similar ether odor. Dissolving a variety of substances (such as rubber; Resin; Fat; AlCl3; S; I2; HgCl2), Unburning. Sexual stability. In the absence of air; Humidity and catalyst, heated to 500 ° C, remained stable. Anti hydrolysis. Solidification point about -22.0 ° C, the boiling point of 121 ° C and 33.2 ° C (4.0 kPa), the relative density of 1.6230 (20 / 4 ° C), the refractive index of 1.50547. No flash point. With ethanol; Ether; Chloroform; Benzene immiscibility. Soluble about 10,000 times the volume of water.
production methods : 1. Ethylene method can be cogeneration TCE and PCE, the following two points Act.
a. direct chlorination of ethylene and chlorine-containing ferric chloride catalyst in the 1,2-dichloroethane solution, 280-450 ° C in the reaction, generate 1,2-dichloroethane, in a further 3% Chloride PCE and TCE, distilled, which were used and NH3; washing; dry derived products.
b. oxychlorination law to the addition of chlorine and ethylene production of 1,2-dichloroethane and 1,2-dichloroethane and chlorine; CuCl2 oxygen to the catalyst and KCl and 425 ° C; 138-kPa conditions for oxychlorination reaction product by cooling; Washable; after distillation, drying, high purity products.
2. Hydrocarbons containing oxidation of methane; Ethane; Propane; Propylene the hydrocarbon mixtures at 50-500 ° C pyrolysis chloride, chlorinated hydrocarbons in the mixture, after distillation separated into a variety of products.
3. Acetylene law acetylene heating chloride and chlorine generated 1,1,2,2 - tetra ethylene oxide, hydrogen chloride used in alkali stripped TCE, and then generate five chlorinated ethylene oxide, and then spend the hydrogen chloride in alkaline off PCE. Because acetylene expensive, has been gradually to replace ethylene law.
purposes : PCE wide range of uses, mainly for the organic solvent; PCE; Solvent degreasing metal, also used as anthelmintics medicine. PCE can be used as a type of fat extraction agent; Smoke and fire extinguishing agent agents can be used TCE and synthetic organic compounds such as fluoride.
