Abstract
A process for the production of butanediol from the hydrogenation of .gamma.-butyrolactone is provided. The process involves passing vaporized .gamma.-butyrolactone, water and hydrogen over a copper zinc catalyst. The incorporation of water with the .gamma.-butyrolactone and hydrogen results in increased productivity of butanediol.
