Abstract

The present invention provides a process for preparing unsubstituted or alkyl-substituted 1,4-butanediol by catalytically hydrogenating, in the gas phase, a gas stream comprising an unsubstituted or alkyl-substituted γ-butyrolactone over a catalyst which contains ≤95% by weight, preferably from 5 to 95% by weight, in particular from 10 to 80% by weight, of CuO, and ≥5% by weight, preferably from 5 to 95% by weight, in particular from 20 to 90% by weight, of an oxidic support, wherein the gas stream comprising unsubstituted or alkyl-substituted γ-butyrolactone contains from 8 to 95% by weight, preferably from 8 to 55% by weight, more preferably from 8 to 20% by weight, of water, based on γ-butyrolactone.
