Abstract
A process is described for the production of 1 4 butanediol and tetrahydrofuran by catalytic hydrogenation of dialkyl maleates. The process consists essentially in the following steps: a) hydrogenating a stream of dialkyl maleate in a first stage of reaction over suitable catalysts to produce dialkyl succinate; b) further hydrogenating the dialkyl succinate in a second stage of reaction by using a different suitable catalyst for producing mainly 1 4 butanediol together with gamma butyrolactone and tetrahydrofuran as co products. In both stages of reaction the conditions as hydrogen/ organic feed ratio pressure and temperature are such to maintain the reactors in mixed liquid/vapor phase.
