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.
