AI Technical Summary

Technical Problem

During the synthesis of trifluoromethylbenzenesulfonyl, the trifluoromethyldiazomethane produced in the reactor causes excessively high pressure, increasing the risk of explosion.

Method used

An explosion-proof trifluoromethylbenzenesulfonyl synthesis device was designed. By setting a stirring shaft and a discharge pipe in the reactor, the generated trifluoromethyldiazomethane is introduced into the reaction chamber to react with the substances in the reaction chamber, thereby reducing the gas pressure in the reactor. The gas flow rate is controlled by an opening and closing mechanism to prevent explosion.

Benefits of technology

It effectively reduced the gas pressure inside the reactor, decreased the risk of explosion, and reduced the harm of trifluoromethyldiazomethane to the environment and personnel, while improving the synchronization of stirring and venting efficiency.

Abstract

This application relates to the field of trifluoromethylbenzenesulfonyl preparation processes, and more particularly to an explosion-proof trifluoromethylbenzenesulfonyl synthesis apparatus, comprising a reaction vessel with an inlet and an outlet, a stirring shaft rotatably mounted inside the reaction vessel, and a discharge pipe connected to a reaction chamber at the end of the discharge pipe furthest from the reaction vessel. The reaction chamber contains a substance for treating trifluoromethyldiazomethane. This application has the effect of reducing the possibility of explosion during the preparation process.
