| Abstract: | Aminoundecanoic acid was synthesized by catalytic ammonolysis of 11-bromoundecanoic acid (Ⅰ).The optimal reaction conditions were that mass ratio of catalyst to Ⅰ was 1∶20,mole ratio of ammonia to Ⅰ was 9∶1,reaction temperature was 20 ℃,and reaction time was 24 h.Under these conditions,the yield was up to 70%.Compared with existing technologies,this technology increased the yield of ammonolysis reaction. |
