PERCHLOROETHYLENE

PERCHLOROETHYLENE： is also known as a whole chloride. In terms of molecular structure, the compounds generated by all hydrogen atoms in ethylene were replaced by chlorine. In 1821, the first time it was made by FaraDay thermal decomposition. Colorless transparent liquid. There is a ether -like smell. Nonflammable. Relative molecular mass 165.85. Relative density 1.6220. The melting point -22.7 ℃. Boiling point 121.2 ℃, 33.2 ℃ (4.000 × 103Pa). The refractive index is 1.5055. The viscosity is 0.839MPA · s (20 ° C). Vapor pressure (× 103Pa): 5.466 (40 ° C), 13.865 (60 ° C), 30.131 (80 ° C), 58.128 (100 ° C). Tetthylene is insoluble in sugar, glycerin and protein, and is slightly soluble in water (0.015 when 25 ° C), which can be dissolved with ethanol, ether, chloroform, benzene, and chlorine organic solvents. Not hydrolyzed. CHEMICALBOOK is still stable at 500 ° C under the presence of airless, moisture and no catalysts. Tethelhyloethane can be generated when hydrogenation. Tiroroethane is generated during chloride. Tetrachloride can also react with bromine to generate a bromine ocean chlorine or diptide chloride. Under the action of a catalyst, it can also react with hydrogen fluoride. Under the existence of light, air, and water for a long time, it is slowly decomposed into trichloride and light, while corrosive metals such as iron, aluminum, and zinc can be suppressed with stabilizers. If there is a activated carbon, heated to 700 ° C to decompose to hex chloride and hex chloroline. Tethalothene can be oxidized by a strong oxidant. Tetthyl chloride can have severe chemical reactions with pink, pink powder, lithium dandruff, tetraoxide, and sodium hydroxide. Tetrachloride is toxic and is a central nervous inhibitor, which can cause headaches, nausea, vomiting, and even coma. The mouse is LD508850mg/kg. The maximum allowable concentration of the workplace is 100 × 10-6.
