Title:
METHOD FOR PRODUCING 1,1-DICHLORO-3,3,3-TRIFLUOROPROPANE
Document Type and Number:
WIPO Patent Application WO/2015/186556
Kind Code:
A1
Abstract:
Provided is a method for producing 1,1-dichloro-3,3,3-trifluoropropane by reacting 1,1-difluoroethylene with dichlorofluoromethane, which suppresses the production of chloroform as a by-product and achieves a product having a high R-243fa concentration.
This method is characterized by obtaining 1,1-dichloro-3,3,3-trifluoropropane by reacting 1,1-difluoroethylene with dichlorofluoromethane in the presence of trifluoromethane.
