Abstract: PCT No. PCT/EP95/02592 Sec. 371 Date Mar. 20, 1997 Sec. 102(e) Date Mar. 20, 1997 PCT Filed Jul. 4, 1995 PCT Pub. No. WO96/01242 PCT Pub. Date Jan. 18, 1996A process is disclosed for the selective hydrogenation of butynediol to 2-butene-1,4-diol using a palladium catalyst to which either copper and zinc, or silver and zinc, or copper, silver and zinc are added as doping agents. In the preferred embodiment, it has been possible, by optimizing the composition of the catalyst, to improve the activity and selectivity of the catalysts in question while also eliminating the need to handle toxic substances during the catalyst manufacturing process.

Abstract: A process for the continuous isolation of phthalic anhydride and maleic anhydride from the reaction gases obtained by catalytic oxidation of o-xylene or naphthalene with air, wherein the reaction gases are treated with a hydrocarbon of boiling range from 115 to 175.degree.C as the solvent in a column, and are then treated with an organic solvent of boiling range from 180 to 290.degree.C in a second column, the phthalic anhydride and maleic anhydride being isolated from the liquid bottom product of the first column.

Abstract: Hydrogenation catalysts which are prepared from mixed crystals of copper-zinc compounds, obtained by precipitation, of the formula Cu1.5-3Zn1-2.5(CO3)1-2(OH)4-6 ? (H2O)O-1 by decomposition at 200 - 500.degree.C, and are used for the catalytic preparation of propanediols of the formula I 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 II 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.

Abstract: 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 DEG to 800 DEG C., for the catalytic preparation of propanediols by hydrogenating hydroxypropionaldehydes at not more than 300 bar pressure and from 50 DEG to 200 DEG 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.
