Title:
PRODUCTION OF 1,1,1,3,3-PENTAFLUOROPROPANE
Document Type and Number:
Japanese Patent JP3164288
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a pentafluoropropane useful as a forming agent, a coolant, etc., in a good efficiency, a high selectivity and a high yield by reacting a chlorotrifluoropropene with hydrogen fluoride under a specific condition.
SOLUTION: This method for producing 1,1,1,3,3-pentafluoropropane is to add hydrogen fluoride to 1-chloro-3,3,3-trifluoropropene in the presence of an addition catalyst such as one or more kinds of compounds selected from a pentahalogenated antimony and a trihalogenated boron to form 1,1,1,3- tetrafluoro-3-chloropropane, then disproportionating the obtained compound in the presence of a disproportionation catalyst such as one or more kinds of compounds selected from the pentahalogenated antimony, a halogenated aluminum to obtain 1,1,1,1,3, 3-pentafluoropropane. Further, it is preferable to use 1-2mols of hydrogen fluoride to 1mol of 1-chloro-3,3,3-trifouoropropene.
