Title:

METHOD OF MANUFACTURING 1-CHLORO-3,3,3-TRIFLUOROPROPYNE

Document Type and Number:

WIPO Patent Application WO/2013/008671

Kind Code:

A1

Abstract:

By means of the present invention, 1-chloro-3,3,3-trifluoropropyne can be obtained with a high yield by reacting 1-chloro-1,2-dihalogeno-3,3,3-trifluoropropane in a liquid phase with a base under moderate conditions. Further, even when using a phase-transfer catalyst, because of two-layer separation after the reaction, this method is a superior industrial production method because there is no load of purification or waste treatment. The obtained 1-chloro-3,3,3-trifluoropropyne is useful as a refrigerant, an etchant, a bioactive substance or functional material such as an aerosol, an intermediate of a functional material, or monomers of a polymer compound.
