Title:
PRODUCTION METHOD FOR 1-CHLORO-3,3,3-TRIFLUOROPROPENE
Document Type and Number:
WIPO Patent Application WO/2013/099485
Kind Code:
A1
Abstract:
This invention is characterized by the catalyst component of a 1,1,1,3,3-pentachloropropane, which is the raw material substrate, being limited to no more than a fixed concentration, in a method in which hydrogen fluoride is reacted with the 1,1,1,3,3-pentachloropropane, and 1-chloro-3,3,3-trifluoropropene is produced. By limiting impurities such as the catalyst component, etc., to no more than a fixed concentration in the 1,1,1,3,3-pentachloropropane, issues during production of 1-chloro-3,3,3-trifluoropropene, such as shortened catalyst life, reaction inhibition, and device scaling or corrosion, can be improved. In addition, 1,1,1,3,3-pentachloropropane can be generated with a high yield and selectively, by causing a telomerization reaction of carbon tetrachloride and vinyl chloride in the presence of a specific metal solubilizing agent, using a catalyst having as the main component thereof elemental metal. As a result, this invention is useful as an industrially predominant production method that obtains a high yield of 1-chloro-3,3,3-trifluoropropene.
