Abstract: The invention relates to a method for the catalytic hydrogenation of adipodinitrile to hexamethylene diamine at a high temperature and at high pressure in the presence of catalysts based on elementary iron as the catalytic component, and ammonia as a solvent. The method is characterised in that a) adipodinitrile is hydrogenated at temperatures of 70 to 220 DEG C and at pressures of 100 to 400 bar in the presence of catalysts based on elementary iron as the catalytic component, and ammonia as a solvent to produce a mixture containing adipodinitrile, 6-aminocapronitrile, hexamethylene diamine and high boilers, until the sum of the 6-aminocapronitrile and adipodinitrile concentration is 1 to 50 wt. % in relation to the ammonia-free hydrogenation mixture; b) ammonia is separated out of the hydrogenation discharge; c) hexamethylene diamine is separated out of the remaining mixture; d) 6-aminocapronitrile and adipodinitrile are separated from the high boilers together or separately and e) 6-aminocapronitrile, adipodinitrile or their mixtures are returned to step a).

Abstract: The invention relates to a method for producing 1,4-butanediol, tetrahydrofuran and .gamma.-butyrolactone by oxidation of butane to a product flow containing maleic anhydride, absorption of maleic anhydride from the product flow with a high-boiling alcohol, which yields a liquid absorption product containing maleic acid half- and diesters and high-boiling alcohol, post-esterification of the liquid absorption product and subsequent hydrogenation of the post-esterified product in the liquid phase. The highboiling alcohol is a polyvalent alcohol with a boiling point at normal pressure of more than 233 ~C and the post-esterified product has an acid value of less than 30 mg KOH/g and a water content of less than 1 weight %.
