    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 is 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.

    Abstract: FIELD: industrial organic synthesis. SUBSTANCE: 1,3-butadiene interacts with alcohol of formula ROH, wherein R is alkyl or alkenyl with 2-20 carbon atoms optionally substituted by one or two C 1 -C 10 -alkoxy or hydroxy-C 1 -C 10 -alkoxy groups; C 6 -C 10 -aryl; C 7 -C 11 -arylalkyl; or methyl at elevated temperatures and pressure in presence of Broensted acid or Ib, VIIb or VIIIb group element complex with phosphorus- or nitrogen-containing ligands to form adducts corresponding to structures C-C=C-C-OR (II) and C-C(OR)-C=C (III). Adduct III is isomerized into adduct II. The latter is subjected to isomerization in presence of transition metal-containing homogeneous or heterogeneous catalyst in liquid phase or in presence of transition metal-containing heterogeneous catalyst in gas phase to form enol ether with structure C-C- C=C-OR (IV). Enol ether IV is subjected to action of hydrogen and water or only water in presence of homogeneous or heterogeneous catalyst as indicated above to form n-butyraldehyde and/or n-butanol, from which alcohol ROH is further released and recycled into the first step of process. EFFECT: increased selectivity of process and yield of products. 7 cl, 1 dwg, 6 tbl, 15 ex
