Disclosed is a novel process for the preparation of epoxyalkanes and epoxycycloalkanes which comprises hydrogenating .gamma.,.delta.-epoxyalkenes or .gamma.,.delta.-epoxycycloalkenes in the presence of a rhodium catalyst. The process is especially useful for the preparation of 1,2-epoxybutane from 3,4-epoxy-1-butene.
