摘　　要：用正交试验法优化Raney-Ni的改良工艺条件,改良得到的Raney-Ni-2#用于肉桂油直接加氢制备苯丙醛,在2L、1m3釜中进行了加氢试验,其选择性达到97.57%,验证了改良的应用效果,证明优化的工艺条件正确、可靠,解决了催化剂选择性的问题,为工业化设计及生产操作提供了可靠的数据。The modification technological conditions of Raney-Ni had been optimized by orthogonal test. The modified Raney-Ni-2# was used for the preparation of 3-phenylpropanal by cinnamon oil directly hydrogenation process. The selectivity reached 97.57% when the hydrogenation experiments were carried out in 2L or lm3 reactor using the modified Raney-Ni-2#. The application result had been checked and the optimized conditions were right and reliable.
