四氯化碳(carbon tetrachloride,CCL4)又名四氯甲烷,常温常压下为无色透明、易挥发、不易燃的油状液体,有类似氯仿的微甜气味。分子量为153.84,沸点76.8℃,微溶于水,可与乙醇、乙醚、氯仿及石油醚等混溶。四氯化碳曾广泛用作溶剂、灭火剂、有机物的氯化剂、香料的浸出剂、纤维的脱脂剂、粮食的蒸煮剂、药物的萃取剂、有机溶剂、织物的干洗剂,金属切削中的润滑剂等,也可用来合成氟里昂、
Carbon tetrachloride (CCL4), also known as tetrachloromethane, is a colorless, transparent, volatile and non-flammable oily liquid with slightly sweet odor similar to chloroform at room temperature and pressure. Molecular weight of 153.84, the boiling point of 76.8 ° C, slightly soluble in water, with ethanol, ether, chloroform and petroleum ether immiscible. Carbon tetrachloride has been widely used as a solvent, fire extinguishing agent, organic chlorination agent, perfume leaching agent, fiber degreasing agent, grain cooking agent, drug extractant, organic solvents, fabric dry cleaners, metal cutting Lubricants, etc., can also be used to synthesize freon,
