Trichloromethane is colorless and transparent liquid with special odor and sweet taste. It is nonflammable and volatile. Pure trichloromethane is sensitive to light, and it reacts with oxygen in the air in contact with light and gradually breaks down into highly toxic phosgene and hydrogen chloride. It can be used as solvent of fat, rubber, resin, oil, wax, phosphorus, and iodine; as solvent of penicillin, essential oil, and alkaloid; as preservative of liver function test.
