Title:
３－クロロ－１，１，２，２－テトラフルオロプロパンの製造方法
Document Type and Number:
Japanese Patent JP7088025
Kind Code:
B2
Abstract:
An efficient production method is provided by which 244ca having a high purity can be produced in a high yield. The production method for 244ca comprises a first step, in which TFPO is reacted with thionyl chloride in the presence of DMF to produce 2,2,3,3-tetrafluoropropanesulfonyl chloride, and a second step, in which the 2,2,3,3-tetrafluoropropanesulfonyl chloride is distilled while being pyrolyzed, thereby obtaining a distillate containing 244ca.
