Carbon Tetrachloride - an overview | ScienceDirect Topics
Carbon Tetrachloride (CASRN 56-23-5) Carbon tetrachloride (CCl 4) is a colorless, highly volatile liquid with a sweetish (ethereal) odor similar to chloroform. It decomposes to highly toxic fumes of phosgene upon heating. Carbon tetrachloride is primarily used in the production of chlorofluorocarbons that are used as refrigerants.
Carbon Tetrachloride - an overview | ScienceDirect Topics
Carbon tetrachloride (CCl 4), also referred to as tetrachloromethane, is a chlorinated hydrocarbon used as a solvent, refrigerant, fire extinguisher, and dry-cleaning agent.
