Abstract: PROBLEM TO BE SOLVED: To improve the storability and handleability of fatty acids by catalytically hydrogenating only carbon-carbon double bonds in the fatty acids and fatty acid derivatives by using a colloid of noble metal as a catalyst without using solvent. SOLUTION: Fatty acids and/or fatty acid derivatives are catalytically hydrogenated selectively under a hydrogen pressure up to 800 bar at maximum by using a catalyst that is a colloid of a single metal, binary or multiple metals selected from the group VIII or IB in the periodic table and is stabilized with a surfactant, for example, an amphoteric betain, or a solution catalyst prepared by dissolving the above-stated catalyst (the homogeneous catalyst) or, a heterogeneous catalyst, that are prepared by using previously formed single, binary or multi-metal colloid and their solutions and depositing them on a carrier. In a preferred embodiment, a bulk type carrier-supported catalyst is used to effect the catalytic hydrogenation reactions in a fixed bed reactor or in a tubular reactor.

Abstract: L'acide malonique ou un de ses sels est produit en rendement élevé par oxydation catalytique de 3- hydroxypropionaldéhyde ou d'acide 3-hydroxypropionique en phase aqueuse avec de l'oxygène ou un gaz contenant de l'oxygène. La réaction se fait en présence d'au moins 10 % en poids de métal noble du groupe du platine par rapport au composant en C3 utilisé. On préfère les catalyseurs de support de Pd et de Pt.

Abstract: Multi-metal catalyst containing iridium and at least one doping element on a support uses at least one element chosen from manganese, cobalt, iron, nickel, copper or ruthenium as the doping agent for iridium. The preparation of substituted aromatic amines by hydrogenating the corresponding substituted aromatic nitro compounds in the presence of the above catalyst is also claimed.

Abstract: The invention relates to a platinum supported catalyst for the anode in a polymer electrolyte membrane (PEM) fuel cell with high resistance to poisoning by carbon monoxide. The catalyst contains the noble metals platinum and ruthenium on a finely divided, conductive support material. It is characterised in that the two noble metals are not alloyed with each other and are present in highly dispersed form on the support material, wherein the crystallite size of the platinum is less than 2 nm and that of the ruthenium is less than 1 nm.
