Abstract: 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.

Key words: catalytic hydrogenation, epoxypentenal, pentadiol, nickel catalyst, palladium catalyst
