Abstract
The 11 aminoundecanoic acid is a monomer of nylon 11.It is synthesized with 11 bromoundecanoic acid and hydrobromic acid as raw materials.The results showed that the optimal reaction condition of ammoniation as follows: the mass ratio of catalyst to reactants was 5%,the reaction time was 24 h,the reaction temperature was 20 ℃, the molar ratio of ammonia to 11 bromoundecanoic acid was 9∶1,under these conditions,the yield of ammonolysis reaction was 72%
The optimal reaction conditions for 11-aminoundecanoic acid synthesization with 11 bromoundecanoic acid and hydrobromic acid are as follows: 5% catalyst, 24 h reaction time, 20°C, 91 molar ratio of ammonia to 11 bromo
