Title:
METHOD FOR PRODUCING TRANS-1-CHLORO-3, 3, 3-TRIFLUOROPROPENE
Document Type and Number:
WIPO Patent Application WO/2017/122703
Kind Code:
A1
Abstract:
The present invention provides a method for efficiently producing 1-chloro-3, 3, 3-trifluoropropene from an intermediate product having a low reactivity. Specifically provided is a method for producing trans-1-chloro-3, 3, 3-trifluoropropene, which is characterized by reacting a halogenated hydrocarbon compound having 3 carbon atoms and represented by general formula (1) with hydrogen fluoride in a gas phase in the presence of a solid catalyst and chlorine.
C3HXClYFZ (1)
(In the formula, X represents 2 or 3; and if X = 2, Y represents an integer of 1-4, Z represents an integer of 0-3, and Y + Z = 4 is satisfied; while if X = 3, Y represents an integer of 1-5, Z represents an integer of 0-4, and Y + Z = 5 is satisfied. In this connection, general formula (1) represents a halogenated hydrocarbon compound having 3 carbon atoms other than trans-1-chloro-3, 3, 3-trifluoropropene.)
