Abstract: The invention relates to a method for producing 1,4-butanediol and possibly .gamma.-butyrolactone and tetrahydrofurane by oxidation of butane or benzol into a product flow containing maleic anhydride, absorption of maleic anhydride from the product flow by means of an inert, high-boiling solvent in an absorption stage, which yields a liquid absorption product, and esterification of said liquid absorption product with a C1-C5 esterification alcohol in an esterification step, yielding an esterification product containing the corresponding diester and high-boiling inert solvent. This is followed by hydrogenation of the esterification product, which results in an hydrogenation product containing the products 1,4-butanediol and optionally .gamma.-butyrolactone and tetrahydrofurane as well as the esterification alcohol. The hydrogenation product is separated by distillation into the products and the esterification alcohol and the esterification alcohol is returned to the esterification zone. Prior to hydrogenation the esterification product i s separated by distillation under reduced pressured into the diester and the inert solvent, the inert solvent is returned to the absorption stage and the diester is hydrogenated in the liquid phase on a fixed-bed catalyst.
