Abstract: In the process for the conversion of maleic acid to gamma-butyrolactone. 1.4-butanediol and/or tetrahydrofuran, a feedstream comprising maleic acid is hydrogenated in a first hydrogenation zone to produce a reaction product comprising succinic acid and unreacted hydrogen which is then supplied to a second hydrogenation zone, where succinic acid is converted to 1,4-butanediol, the temper atures of the feedstream comprising maleic acid and the first hydrogenation zone are controlled such that the temperature of mal eic acid in the feedstream and the first hydrogenation zone does not exceed about 130 DEG C, thereby minimizing the corrosive effects of the maleic acid and prolonging reactor life and improving overall process economics.
