Abstract: Metal catalysts consist of hollow molds. An Independent claim is also included for the production of metal catalysts comprising spraying metal powders together with a binder onto molds made of combustible material, i.e. polystyrene, and calcining the material forming the hollow mold. Preferred Features: The catalysts comprise hollow spheres having a diameter of 0.5-20 mm and a wall thickness of 0.1-5 mm. The catalysts have an impermeable casing having an open porosity of maximum 80% and made up of different layers.

Abstract: A process for producing 3-aminomethyl-3,5,5-trimethylcyclohexyl amine (isophorone diamine) from isophorone nitrile. Isophorone nitrile is iminated in a first stage and then the reaction mixture is subjected to aminating hydrogenation in a second stage in the presence of a fixed bed hydrogenation catalyst based on Raney cobalt. The fixed bed hydrogenation catalyst is produced in a special manner by mixing a powdery Co-containing Raney alloy with powdery cobalt, sintering the powdery mixture to shaped moldings and then activating by leaching with alkali hydroxide solution. The yield and/or space-time yield in isophorone diamine production can be increased.

Abstract: Prepn. of 3-aminomethyl-3,5,5-trimethylcyclohexylamine (isophorone diamine (IPDA)) from 3-cyano-3,5,5-trimethylcyclohexanone (isophorone nitrile (IPN)) comprises: (a) partially converting IPN in presence or absence of an iminating catalyst with NH3 into 3-cyano-3,5,5-trimethyl cyclohexane imine; and (b) hydrogenating the reaction mixt. from (a) by adding a 1-3C alcohol using a solid bed hydrogenation catalyst on a Raney-Co catalyst at 50-150 deg C under a pressure of 3-10 MPa. The novelty is that the hydrogenation catalyst is produced by: (i) intensively mixing a powdered Co-alloy and a powdered Co as binder, where the Co-alloy contains Co and opt. promoters and/or leachable alloying components of Al, Zn and Si in wt. ratio of 30-70 and 75-25; (ii) sintering the powdered mixt. by a mechanically stable moulding of 1.3-5.5 g./cm density, up to 0.5 cm /g. pore volume (water adsorption) and a less than 1 m /g. BET surface area (DIN 66132); and (iii) activating the sintered moulding by partially leaching the leachable alloying components using an alkali metal hydroxide lye.
