The present invention relates to 1-chloro-1,1,3,3,3-pentafluoropropane (HCFC-235fa) useful as an intermediate in the production of 1,1,1,3,3-pentafluoropropane (HFC-245fa). ). The method includes the step of reacting HCFC-235fa with hydrogen in the presence of a reduction catalyst, wherein the HCFC-235fa converts CCl 3 CH 2 CCl 3 into hydrogen fluoride and a fluorination catalyst. A method for producing HFC-245fa, produced by reacting in either the liquid phase or the gas phase. [Selection figure] None |
