Azeotropic COMPOSITIONS INCLUDING WATER AND a hydrofluorocarbon, METHOD FOR REMOVING WATER SOLUTION DISTILLATIVE azeotropic AND METHOD FOR PRODUCING HYDROFLUOROALKANE.

摘要

The invention relates to binary azeotropic compositions between water and 1,1-dichloro-1-fluoroethane, 1-chloro-1,1-difluroéthane, 1,1,1-trifluoroethane, 1,1,1 , 2-tétrafluro-ethane, 1,1-difluoroethane or trifluoroethylene, a dewatering process solutions by azeotropic distillation by means of these compositions and to a process for producing a hydrofluoroalkane in which Water is removed from the reaction product mixture by azeotropic distillation by means of these compositions.
