摘要：
The present invention provides a method for producing trifluoromethanesulfonyl chloride. This method includes the step of reacting trifluoromethanesulfonic acid with phosphorous trichloride and chlorine. With this method, trifluoromethanesulfonyl chloride can be easily and highly selectively produced at high yield. The reaction may be carried out at about atmospheric pressure. Furthermore, the reaction may be carried out in the presence of phosphorus oxychloride either under a pressurized condition or at about atmospheric pressure.
