【Abstract】 s DMCHA was prepared from cyclohexylamine with no catalyst at normal pressure, and the temperature was not higher than 100℃. The proposed method not only had properties of mild reaction, simple and convenient operation, short reaction time, but also could get good reproducibility and low cost, the yields and purities of the method were above 80% and 99.9% respectively.更多还原
