Title:
１－クロロ－２，２－ジフルオロエチレンの製造方法
Document Type and Number:
Japanese Patent JP7219625
Kind Code:
B2
Abstract:
To provide a method for producing 1-chloro-2,2-difluoroethylene, from 1,2-dichloro-1,1-difluoroethane as the source material, wherein the production is possible under a relatively low temperature condition, and a decrease in the reaction conversion rate is minimized even in the long-term production, and the method can be conducted industrially.SOLUTION: A method for producing 1-chloro-2,2-difluoroethylene includes the reaction of 1,2-dichloro-1,1-difluoroethane in a gas phase in the presence of active carbon as a solid catalyst.SELECTED DRAWING: None
