| Химическое название | трихлорэтилен |
| Аббревиатура | TCE |
| Номер по CAS | 79-01-6 |
| Химическая формула | C2HCl3 |
| Молекулярная масса | X |
| Внешний вид | Colorless transparent liquid with a characteristic odor similar to chloroform |
| Физические свойства | Density: 1.46 g/cm³; Boiling Point: 87.1°C; Soluble in organic solvents such as ethanol, ether, acetone, carbon tetrachloride, and chloroform; Slightly soluble in water; Volatile and flammable at higher temperatures; Vapor can form explosive mixtures with air |
| Химическая стабильность | Unstable; Oxidizes in air to produce phosgene, carbon monoxide, and hydrogen chloride without stabilizers; Resistant to most metals at ordinary temperatures, but reacts with acids, water, and metal powders under certain conditions |
| Методы производства | Prepared from acetylene, with tetrachloroethane as a diluent and anhydrous ferric chloride as a catalyst; Alternatively, ethylene and chlorine are passed into a reaction tower to produce a mixture of tetrachloroethane and pentachloroethane, which is then cracked in the presence of a barium chloride catalyst on activated carbon to produce trichloroethylene and tetrachloroethylene |
| Приложения | Used as a degreaser for metals, a solvent, and an extractant in industries such as electroplating, electrical machinery, medicine, and dry cleaning; Also used as an anesthetic and in the production of tetrachloroethylene for anthelmintic drugs |
| Условия хранения | Store in a cool, well-ventilated, dry warehouse; Keep in a sealed container and avoid sunlight; Store separately from food chemicals and strong alkalis; Keep away from heat sources |
| Опасность для здоровья | Inhibits the central nervous system, leading to general anesthesia; Long-term exposure may cause organic damage; Causes dermatitis upon skin contact; Causes mild irritation and tearing when in contact with eyes |
