Title:
1,2,3,4-TETRACHLORO-1-FLUOROBUTANE AND METHOD FOR PRODUCING SAME, AND METHOD FOR PRODUCING 1,2,3,4-TETRACHLORO-1,1,2,3,4,4-HEXAFLUOROBUTANE
Document Type and Number:
WIPO Patent Application WO/2022/249852
Kind Code:
A1
Abstract:
Provided is a method for producing 1,2,3,4-tetrachloro-1-fluorobutane, which serves as a starting material that enables the production by a stable reaction of 1,2,3,4-tetrachloro-1,1,2,3,4,4-hexafluorobutane. The method for producing 1,2,3,4-tetrachloro-1-fluorobutane comprises a chlorination step of obtaining 1,1,2,3,4-pentachlorobutane by chlorinating 1,2,3,4-tetrachlorobutane by reacting 1,2,3,4-tetrachlorobutane with chlorine gas by a photoreaction in the liquid phase; and a fluorination step of obtaining 1,2,3,4-tetrachloro-1-fluorobutane by fluorinating the 1,1,2,3,4-pentachlorobutane yielded by the chlorination step.
