【Abstract】 In this paper,the technology of synthesizing C 17 H 35 CONHCH 2CH 2NHOCH 35 CH 17 .From stearic acid and ethylenediamine with strong acids as catalyst was researched.The reaction using different marenials as catalysts were researched.Experiment results showed that soild super strong acid was very better because the reaction time and the yield was higher.更多还原
