Abstract:
1. A process for the production of 2-chloro-1,1,1,2-tetrafluoropropane which comprises fluorinating 1,1,2,3-tetrachloropropene with hydrogen fluoride to produce an intermediate product stream comprising hydrogen fluoride, 2-chloro-3,3,3-trifluoropropene, and hydrogen chloride; recovering at least a portion of the hydrogen chloride; and reacting 2-chloro-3,3,3,-trifluoropropene with hydrogen fluoride, in a liquid phase reaction in the presence of at least a portion of the recovered hydrogen chloride and a liquid phase fluorination catalyst, wherein the hydrogen chloride is added into the reaction at a pressure of about 100 psig or more.
