Raney copper which is doped with at least one metal from the group comprising iron and/or noble metals is used as a catalyst in the dehydrogenation of alcohols.

Raney copper

Process for the preparation of isophorone diamine from isophorone nitrile, isophorone nitrilimine or mixtures containing isophorone nitrile and/or isophorone nitrilimine by hydrogenation through to amine in the presence of at least ammonia, hydrogen and a formed Raney hydrogenation catalyst based on cobalt, nickel, copper and/or iron, wherein the Raney catalyst is present in the form of hollow bodies.

A process for the production of 1,3-propanediol by heterogeneously catalyzed hydrogenation of 3-hydroxypropionaldehyde in an aqueous solution at 30 to 180&deg; C., at a hydrogenation pressure of 5 to 300 bar and a pH value of 2.5 to 7.0, wherein ruthenium on an oxide support is used as the catalyst.

Process for the production of 1,3-propanediol by hydrogenating 3-hydroxypropionaldehyde

A process for preparing catalytically active coatings for the synthesis of hydrogen cyanide on moulded items substantially consisting of aluminum oxide. The catalytically active coatings contain, as active components, at least one platinum group metal and a nitride waich are applied to the moulded item by means of a coating dispersion which contains the active components as finely divided solids. This means that the hitherto conventional production of aluminum nitride during the forming process is not required. The coatings therefore achieve their final activity level, which is well above that of conventional coatings, very rapidly. In addition, these catalysts can be started up under high load and have a lower operating temperature.

An ammoxidizable compound is reacted with an ammonium salt, especially an inorganic ammonium salt, in the presence of a source of oxygen and an ammoxidation catalyst at 100 to 700.degree. C., preferably 200 to 700.degree. C., in order to produce cyano compounds of the formula R--CN, in which R is H or an organic group.
