Document Type and Number:
WIPO Patent Application WO/2022/014488
Kind Code:
A1
Abstract:
The present invention provides a method for producing 1233yd in a vapor phase, said method having a high conversion rate of a starting material and enabling the achievement of 1233yd with high selectivity, while suppressing the production amount of impurities. A method for producing 1-chloro-2, 3, 3-trifluoropropene by subjecting 3-chloro-1, 1, 2, 2-tetrafluoropropane to a hydrogen fluoride elimination reaction in a vapor phase in the presence of a catalyst, said method being characterized in that a metal compound catalyst, which is activated in a vapor phase by a fluorine compound that does not contain a chlorine atom, is used as the catalyst.
