<p>Process for the production of 1,4-Butanediol by vapour phase catalytic hydrogenation of gamma-butyrolactone, maleic and/or succinic anhydride methyl esters or mixtures of gamma-butyrolactone and maleic and/or succinic anhydride esters, characterised by the fact that, in the operating conditions described in the process, by feeding hydrogen gas containing carbon monoxide to the reaction, a concomitant production of synthesis methanol is obtained, and conversion values relating to methanol production are improved.</p> |
