Abstract
A process for producing 1-chloro-3,3,3-trifluoropropene (HCFC-1233zd) from 1,1,1-3,3-pentachloropropane (HCC-240fa) by its reaction with hydrogen fluoride, the reactants are reacted in a liquid phase reaction at a temperature of less than 150° C. in the presence of a Lewis acid catalyst or mixture of Lewis acid catalysts, and hydrogen chloride and HCFC-1233zd formed in the reaction are continuously removed and the HCFC-12333zd is isolated.
