Title:
1-CHLORO-2,3,3,3-TETRAFLUOROPROPENE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/146189
Kind Code:
A1
Abstract:
In a method for obtaining 1-chloro-2,3,3,3-tetrafluoropropene(1224yd) by reducing 1,1-dichloro-2,3,3,3-tetrafluoropropene(1214ya), provided is a method for efficiently manufacturing 1224yd, wherein generation of by-products such as 2,3,3,3-tetrafluoropropene and 1,1,1,2-tetrafluoropropane that are over-reductants is suppressed. This 1-chloro-2,3,3,3-tetrafluoropropene manufacturing method is characterized by reacting, in a gaseous phase, 1,1-dichloro-2,3,3,3-tetrafluoropropene with hydrogen in the presence of a palladium catalyst-supporting carrier in which a palladium catalyst having a specific surface area of 40 m2/g or less is supported on a carrier.
