Audited Supplier Physical and chemical properties of tetrachloroethylene, also known as perchloroethylene, molecular structure is a chemical compound generated by the replacement of all hydrogen atoms in ethylene by chlorine, and was first prepared in 1821 by Faraday pyrolysis of hexachloroethane. Colorless transparent liquid. It has an etheric odor. It's not combustible. Molecular weight 165.85. The relative density is 1.6220. Melting point -22.7ºC. Boiling point 121.2ºC, 33.2ºC(4.000×103Pa). Refractive index 1.5055. Viscosity 0.839mPa·s(20ºC). Vapor pressure (x 103 pa) : 5.466 (40 ºC), 13.865 (60 ºC), 30.131 (80 ºC), 58.128 (100 ºC). Tetrachloroethylene is insoluble in sugar, glycerin and protein, slightly soluble in water (0.015 at 25ºC), and can be miscible with ethanol, ether, chloroform, benzene and chlorine organic solvents. It does not hydrolyze. In the absence of air, no moisture and no catalyst, it is still stable even when heated to 500 ° C. When hydrogenated, tetrachloroethane is formed. Hexachloroethane is formed when chlorinated. Tetrachloroethylene can also react with bromine to form a bromotrichloride or dibromodichloride compound. Under the action of catalyst, it can also react with hydrogen fluoride. In the presence of light, air and water for a long time, it is slowly decomposed into trichloroacetaldehyde and phosgene, and corrosion of iron Chemicalbook, aluminum, zinc and other metals can be inhibited by adding stabilizers. If activated carbon is present, it is heated to 700ºC and decomposed into benzene hexachloride and hexachloroethane. Tetrachloroethylene can be oxidized by strong oxidants. Tetrachloroethylene can react violently with barium powder, beryllium powder, lithium chips, nitrous oxide, and sodium hydroxide. Tetrachloroethylene is a toxic central nervous system depressant that can cause headaches, nausea, vomiting, and even coma. Mice transoral LD508850mg/kg. The maximum allowable concentration in the workplace is 100×10-6. The above information is edited by Xiaonan of Chemicalbook. In industry, tetrachloroethylene is mainly used as solvent, organic synthesis, metal surface cleaner and dry cleaning agent, desulfurizer, heat transfer medium. Used medically as a dewormer. It is also an intermediate for making trichloroethylene and fluorinated organics. The general population may be exposed to low concentrations of tetrachloroethylene through the atmosphere, food and drinking water. Tetrachloroethylene has good solubility for many inorganic and organic compounds, such as sulfur, iodine, mercury chloride, aluminum trichloride, fat, rubber and resin, etc. This solubility is widely used as metal degreasing cleaning agent, paint remover, dry cleaning agent, rubber solvent, ink solvent, liquid soap, high-grade fur and feather degreasing; Tetrachloroethylene is also used as an insect repellent (hookworm and ginger tablet); Finishing agent for textile processing.
