  • Coproduction of butanediol and tetrahydrofuran and their subsequent separation from the reaction product mixture
    Patent number: 4656297
    Abstract: Mixtures of tetrahydrofuran and 1,4-butanediol at a predetermined mole ratio are produced by the hydrogenation of dimethylsuccinate in the presence of a copper chromite catalyst wherein said ratio is controlled by conducting the hydrogenation within a particular temperature range. Methanol is added to the ester feed to increase conversion and reduce transesterification. Tetrahydrofuran and 1,4-butanediol are separated from a mixture which also contains water and methanol by a series of distillations including a superatmospheric distillation.
