Abstract
Provided is a method for producing trans-1-chloro-3,3,3-trifluoropropene usable as a raw material for a foaming agent for a hard polyurethane foam, a solvent, a cleaning agent, a cooling medium, a working fluid, a propellant, a fluorinated resin, etc., the method involving a step of bringing cis-1-chloro-3,3,3-trifluoropropene into contact with a catalyst, wherein the catalyst includes a fluorinated metal oxide or a metal fluoride each produced by applying a fluorination treatment to a metal oxide containing one kind or two or more kinds of metals and containing aluminum atoms that make up 50 at. % or more of metal atoms to thereby substitute some or all of oxygen atoms in the metal oxide with fluorine atom(s), wherein the fluorinated metal oxide or the metal fluoride is a compound produced through a drying treatment at 400 to 600° C.
