Method for producing trans-1-chloro-3,3,3-trifluoropropene

A production method of trans-1-chloro-3,3,3-trifluoropropene, comprising reacting a raw reactant material containing a plurality of halogenated C3 hydrocarbon compounds represented by the following general formula (1) with hydrogen fluoride in a gas phase in the presence of a solid catalyst and chlorine

• C3HXClYFZ (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 C3 hydrocarbon compound other than trans-1-chloro-3,3,3-trifluoropropene,
• wherein, in the reacting, the raw reactant material further comprises a C3 hydrocarbon compound represented by the following general formula (2)
• C3HVFW (2)
• wherein, when V+W=8, V is an integer of 0 to 8;
• when V+W=6, V is an integer of 0 to 6;
• and, when V+W=4, V is an integer of 0 to 4.
