Method for preparing 1,1,1,3,3-pentafluoropropane

摘要

A process for the production of C2-C4 hydrofluorocarbon, such as 1,1,1,3,3-pentafluoropropane, by contacting a non-fluorinated hydrochlorocarbon with a fluorinating agent, such as hydrogen fluoride, in a liquid catalyst system preferably comprising fluorinated superacid catalyst prepared from SbF₅, NbF₅, TaF₅ or TaF₅/SnF₄ and HF.
