Abstract: PROBLEM TO BE SOLVED: To hydrogenate polyunsaturated hydrcarbon(s) in a fluid by bringing the hydrocarbon(s) into contact with a catalyst pack in the presence of free hydrogen. SOLUTION: Polyunsaturated 2-8C hydrocarbon(s), esp. 2-8C alkyne and/or 4-8C alkynene and/or 4-8C alkadiene, is brought into contact with a catalyst pack in the presence of free hydrogen. The catalyst pack is prepared by applying an active substance as a catalyst and/or promoter to a woven mesh, knitwear or foil as support material; for example, the support may be coated with the catalytically active compound and promoter by e.g. vacuum deposition. By virtue of using the catalyst, the polyunsaturated hydrocarbon(s) can be converted to the corresponding monounsaturated hydrocarbon(s) in high selectivity and yield, and hydrogenation of isobutene does not occur.

Abstract: Production of propionic acid (or its ester) comprises: (1) partial dehydrogenation of propane to give a mixture (A); (2) partial oxidation of propylene in (A) to form a mixture (B); and (3) hydrogenation of the acrylic acid in (B) (directly and/or after esterification) to form a mixture (C) containing propionic acid and/or its ester At least part of the hydrogen used in step (3) is that formed in step (1). Production of propionic acid (or its ester) from acrylic acid (or its ester) comprises: (1) heterogeneously catalyzed partial dehydrogenation of propane in a first reaction zone, to give a product gas mixture (A) containing molecular hydrogen, propylene and unconverted propane; (2) charging the propylene in (A) to a second reaction zone, in which the propylene is subjected to selective, heterogeneously catalyzed partial gas phase oxidation with molecular oxygen to form a product gas mixture (B) containing acrylic acid; and (3) charging the acrylic acid in (B) (directly and/or after esterification) to a third reaction zone, in which the acrylic acid (or ester) is hydrogenated with molecular hydrogen to form a product gas mixture (C) containing propionic acid and/or its ester. At least part of the hydrogen used in step (3) being that formed in step (1).

Abstract: A catalyst packing which can be produced by vapor deposition and/or sputtering of at least one substance active as catalyst and/or promotor onto woven or knitted fabrics or sheets as support material is used in a process for catalytic distillation in which a heterogeneously catalyzed reaction is combined with a simultaneous distillation or rectification over the catalyst packing.

Abstract: The disclosure is a process for preparing mixtures of monoolefinic C5 mononitriles having nonconjugated C=C- and C=N bonding by catalytic hydrocyanation of a hydrocarbon mixture containing 1,3-butadiene, by first diminishing the proportion of those components in the hydrocarbon mixture which impair the catalytic hydrocyanation and then subjecting the resulting mixture to catalytic hydrocyanation.

Abstract: A formed catalyst containing Cu and oxygen-containing Ti compounds and produced with the addition of metallic Cu is used for the production of amines by the reaction of an alcohol, aldehyde or ketone with ammonia or an amine in the presence of hydrogen. Production of amines comprises the reaction of a primary or secondary alcohol, aldehyde or ketone with ammonia or a primary or secondary amine at an elevated temperature and pressure in the presence of H2 and a formed catalyst containing Cu and oxygen-containing Ti compounds and produced with the addition of metallic Cu.
