摘　　要：研究了多相钯和镍催化剂上4,5-环氧-2-戊烯醛的催化加氢。发现钯催化剂上加氢产物为4,5-环氧戊醛(1)和2-羟基四氢吡喃(2),而镍催化剂上加氢产物为2和1,5-戊二醇(3)。1、2和3的最高收率分别为58.8%、62.0%和84.7%。讨论了不同催化剂对加氢产物组成的影响。The catalytic hydrogenation of 4,5-epoxy-2-pentenal on Pd and Ni catalysts has been studied.For Pd catalyst the products obtained were 4,5-epoxypentanal (1) and 2-hydroxytetrahydropyran (2), and for Ni catalyst they were (2) and 1,5-pentadiol (3).The maximum yield of 1,2 and 3 is 58.8%, 62.0% and 84.7%, respectively. The influences of various catalysts on the composition of hydrogenation products were discussed.
