Description
Tetrachloromethane (synonyms: perchloromethane, carbon tetrachloride, CTC) consists of methane which has undergone perhalogenation with chlorine. It is a liquid, formerly widely used as a solvent, now used mainly as feedstock for the manufacture of other substances or as a process agent.
Detailed description
Tetrachloromethane is highly ozone-depleting (ozone depletion potential or ODP = 1.1). For this reason, its use is strictly controlled under the Montreal Protocol. It is also toxic, causing hepatic lesions and cumulative damage to the central nervous system. For these reasons, its use is limited today to feedstock and some process agent applications.
