摘　　要：对肉桂油直接加氢制备高附加值产品苯丙醛进行研究,在2 L、1 m3反应釜中对其直接加氢工艺条件进行试验。结果表明:在50℃、压力为4.0 MPa的条件下,利用质量分数3%的雷尼镍-2#作催化剂,反应4 h,得到的苯丙醛质量分数达到97.74%,收率达到62.24%。Direct hydrogenation of cinnamon oil to prepare phenylpropyl aldehyde was studied.The hydrogenation experiments were carried out in the 2 L and 1 m3 reactors respectively.The results showed that the best conditions were as follows：3 % mass fraction of Raney-Ni 2# as catalyst,reaction temperature 50 ℃,reaction pressure 4.0 MPa,time 4.0 h.Under these conditions,mass fraction of the obtained phenylpropyl aldehyde reached 97.74 %,and the yield reached 62.24 %.
