    摘要： Hydrogenation catalysts, which have a specific surface area of from 50 to 150 square meters per gram, solely or partially contain crystals having a spinel structure and copper in the form of copper oxide, and have been obtained by precipitating copper and aluminum in a ratio of from 0.25 to 3 atoms of copper per atom of aluminum from their compounds in the presence of a carbonate at a pH of from 4.5 to 9 and calcining the resulting precipitate at from 300.degree. to 800.degree. C., for the catalytic preparation of propanediols by hydrogenating hydroxypropionaldehydes at not more than 300 bar pressure and from 50.degree. to 200.degree. C., and processes for the preparation of propanediols by the use of such catalysts.The propanediols obtainable by the process of the invention, in particular 2,2-dimethylpropane-1,3-diol, are valuable starting materials for the preparation of lubricants, plastics, surface coatings and synthetic resins, for example corresponding polyesters.

    摘要： Hydrogenation catalysts which are prepared from mixed crystals of copper-zinc compounds, obtained by precipitation, of the formulaCu.sub.1.5-3 Zn.sub.1-2.5 (CO.sub.3).sub.1-2 (OH).sub.4-6.(H.sub.2 O).sub.0-1by decomposition at 200.degree.-500.degree. C., and are used for the catalytic preparation of propanediols of the formula ##STR1## where the R's may be identical or different and each is an aliphatic, araliphatic or aromatic radical, or the two R's together with the adjacent carbon atom are members of an alicyclic ring, by hydrogenating hydroxypropionaldehydes of the formula ##STR2## where R has the above meanings, and to processes for the preparation of propanediols, using such catalysts. The propane-1,3-diols obtainable by the novel process are valuable starting materials for the preparation of lubricants, plastics, surface coatings and synthetic resins, for example of polyesters derived from the propanediols.
