Abstract
The present invention provides a method for efficiently producing 1-chloro-3,3,3-trifluoropropene from a low-reactivity intermediate product. More specifically, provided is a method for producing trans-1-chloro-3,3,3-trifluoropropene, characterized by reacting a halogenated Chydrocarbon compound represented by the following general formula (1) with hydrogen fluoride in a gas phase in the presence of a solid catalyst and chlorineCHClF  (1)wherein X is 2 or 3; when X=2, Y is an integer of 1 to 4, Z is an integer of 0 to 3, and Y+Z=4; and, when X=3, Y is an integer of 1 to 5, Z is an integer of 0 to 4, and Y+Z=5; provided that the general formula (1) represents any halogenated Chydrocarbon compound other than trans-1-chloro-3,3,3-trifluoropropene.
