| Abstract: | The reaction process and technology control points during the first phase amination of bisultap synthesis were analyzed and investigated. The specific factors to increase amination yield and the importance of first acidification were pointed out. The technology conditions in the trial experimentation were optimized. The by-reactions were reduced. The main product yield was increased by 10%. The technology improvement method in the large-scale production was pointed out. |
