| titleOfInvention | Synthesize the method and its system of N-acetylsulfanilyl chloride as sulfonating agent with sulfur trioxide |
| abstract | Method and its system the present invention relates to synthesize N-acetylsulfanilyl chloride as sulfonating agent with sulfur trioxide, it is comprised the following steps：（a）To antifebrin and thionyl chloride is sequentially added in reactor, stirring is warming up to 40 ~ 70 DEG C；（b）To sulfur trioxide gas are passed through in reactor, reacted 3 ~ 15 hours at 40 ~ 70 DEG C, make the antifebrin conversion complete, stop being passed through sulfur trioxide gas；（c）Reactor temperature is risen to 65 ~ 80 DEG C, the thionyl chloride is recovered under reduced pressure, cool down.Use sulfur trioxide to synthesize N-acetylsulfanilyl chloride for sulfonating agent, so both can guarantee that the quality of N-acetylsulfanilyl chloride, avoid producing waste water and spent acid again, saved processing cost, be conducive to environmental protection. |
