Abstract

The invention comprises 3,3-dichloro-1,1: 2,2-tetrafluoropropan and its preparation by the chlorination of 3 - chloro - 1,1: 2,2 - tetrafluoropropane, for example in the presence of ultra-violet light either in the liquid phase at between 20 DEG C. and 80 DEG C. or in the vapour phase at between 54 DEG C. and 250 DEG C. or in the absence of ultra-violet light at between 250 DEG C. and 600 DEG C. In all methods an excess of the halohydrocarbon is preferred. 3 - Chloro - 1,1: 2,2 - tetrafluoropropane may be prepared from 2,2: 3,3-tetrafluoropropan-1-ol by warming with p-toluene sulphonyl chloride in aqueous sodium hydroxide and treating the resultant 2,2:3,3 - tetrafluoropropyl - p - toluene sulphonate - 1 with potassium chloride in the presence of ethylene glycol. Specification 907,439 is referred to.ALSO:The invention comprises inhalant anaesthetic compositions containing 3, 3-dichloro-1, 1 : 2, 2-tetrafluoroproxane in admixture with oxygen and optionally one or more known inhalant anaesthetics for example, nitrous oxide, ether, chloroform, cyclopropane or halothane. The invention also includes a process for producing anaesthesia in animals (excluding man) using any of the above compositions. Specification 907,439 is referred to.
