Abstract

Inhalation anaesthetic mixtures comprise a mixture of from 13 to 17% by weight of methyl-n-propyl ether and from 83 to 87% by weight of 2-bromo-2-chloro-1,1,1-trifluoroethane, 95% by volume of which mixture distils at a temperature of 53.6\sB0.3 DEG C. at 760 mm. of mercury. The preferred mixture is the azeotrope which distils at the above temperature and contains 15.25% of the methyl-n-propyl ether and 84.25% of the 2-chloro-2-bromo-1,1,1-trifluoroethane. The mixtures may be prepared by mixing the components in the desired proportions or by mixing them in any proportions and collecting the fraction which, on distillation of the mixture, passes over at 53.6\sB0.3 DEG C. at 760 mm. of mercury. Specification 831,860 is referred to.
