哌啶催化合成工艺研究

THE TECHNOLOGICAL PROGRESS OF CATALYTIC SYNTHESIS OF PIPERIDINE

研究了在ＮＨＤ－９９催化剂存在下，催化剂用量、反应温度、反应压力及反应时间对哌啶收率的影响．在最佳工艺条件下，哌啶收率可达９６．１５％，产品纯度达到９８．８％．

The impact of the amount of catalyst, temperature, pressure, and reaction time on the yield of the piperidine in the presence of NHD-99 catalyst was studied. Under a optimum condition,the yield of piperidine was up to 96.1%and the purity above 98.8%.
