Disclosed is a process for producing 1-chloro-3,3,3-trifluoropropene or 1,3,3,3- tetrafluoropropene, which comprises reacting 1,1,1,3,3- pentafluoropropane with hydrogen chloride in a gas phase in the presence of a solid catalyst. By using a specific catalyst such as a catalyst comprising chromium supported on alumina or activated charcoal and an alumina catalyst, it becomes possible to produce 1-chloro-3,3,3-trifluoropropene and 1,3,3,3- tetrafluoropropene from 1,1,1,3,3-pentafluoropropane, which is a compound that is available and can be produced on an industrial scale, in high yield. |
