Compositions containing the fluoride of 1996 and 1,1,1,3,3 - pentafluorobutane, for the separation of mixtures comprising such compositions and method for the synthesis of 1,1,1,3,3 - pentafluorobutane
Compositions containing the fluoride of 1996 and 1,1,1,3,3 - pentafluorobutane, for the separation of mixtures comprising such compositions and method for the synthesis of 1,1,1,3,3 - pentafluorobutane
The invention relates to the azeotropic compositions hfc - 365mfc / hf, a method of separation of mixtures of such compositions hfc - 365mfc / hf by two distillation at different pressures, as well as a process for the synthesis of hfc - 365mfc integrating this process, the separation and a recycling of certain fractions to the step of hydrofluorination.
