摘要:
A process for dehydrogenating 1,4-butanediol to .gamma.-butyrolactone in the gas phase in the presence of a copper-containing catalyst, wherein the catalyst contains 4-40% by weight of copper and 0-5% by weight of Na.sub.2 O, based on the total weight of the catalyst, on a carrier consisting of 80-100% by weight of SiO.sub.2 and 0-20% by weight of CaO.
