Abstract[English]
A process for the production of dimethyl succinate and 1, 4 butanediol is disclosed. The process comprises a 1, 4 butanediol production process comprising a first esterification section and a hydrogenolysis section and a dimethyl succinate production process comprising a second esterification section and a hydrogenation section. The process is characterised in that at least one stream is taken from the dimethyl succinate production process and fed to the 1, 4 butanediol production process.[French]
L'invention concerne un procédé de production de succinate de diméthyle et de 1,4 butanediol. Le procédé comprend un processus de production de 1,4-butanediol comprenant une première section d'estérification et une section d'hydrogénolyse et un processus de production de succinate de diméthyle comprenant une seconde section d'estérification et une section d'hydrogénation. Le procédé est caractérisé en ce qu'au moins un flux est tiré du processus de production de succinate de diméthyle et amené au processus de production de butanediol 1, 4.
