    摘要： A process for variably preparing mixtures of optionally alkyl-substituted BDO, GBL and THF by two-stage hydrogenation in the gas phase of C4 dicarboxylic acids and/or derivatives thereof, which comprises a) hydrogenating in a gas phase a gas stream of C4 dicarboxylic acids and/or derivatives thereof over a particular catalyst at a particular pressure and temperature to give a stream mainly containing of optionally alkyl-substituted GBL and THF, b) removing any succinct anhydride, c) converting the products remaining predominantly in the gas phase in the partial condensation, THF, water and GBL to give a stream comprising a mixture of BDO, GBL and THF, d) removing the hydrogen from the products and recycling it into the hydrogenation, e) distillatively separating the products, THF, BDO, GBL and water, if appropriate recycling a GBL-rich stream or if appropriate discharging it, and working up BDO, THF and GBL distillatively, and setting the ratio of the products, THF, GBL and BDO, relative to one another within the range from 10 to 100% by weight of THF, from 0 to 90% by weight of GBL and from 0 to 90% by weight of BDO only by varying the temperatures in the two hydrogenation zones and also if appropriate the GBL recycle stream.

    摘要： The present invention relates to a process for preparing 3-alkoxypropan-1-ols of the general formula I by catalytic hydrogenation of esters of the general formula II, where the radicals R1 and R2 and R3, R4 and R5 are each, independently of one another, a straight-chain or branched C1-C20-alkyl radical which may optionally be substituted by one or more C1-C20-alkoxy radicals or interrupted by one or more oxygen atoms in the chain, C6-C20-aryl, C7-C20-arylalkyl which may optionally be substituted by one or more C1-C20-alkoxy radicals or interrupted by one or more oxygen atoms in the alkyl chain, C7-C20-alkylaryl which may optionally be substituted by one or more C1-C20-alkoxy radicals or interrupted by one or more oxygen atoms in the alkyl chain, a C1-C20-cycloalkyl radical which may optionally be substituted by one or more C1-C20-alkoxy radicals and R2, R3 and R4 can, independently of one another, also be hydrogen, over chromium- and nickel-free catalysts.
