Abstract
The invention relates to a process for the preparation of aldehydes by hydrogenating carboxylic chlorides of the general formula RCOCl, wherein R stands for alkyl, isoalkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, aromatic, heterocyclic or substituted heterocyclic group, the substituents being alkyl, halogen, hydroxy, alkoxy, carboxyl, carbonyl and nitro groups wherein the hydrogenation is carried out in the presence of an alloy catalyst comprising at least one element of the platinum group and at least one element of the groups IB and IIB of the periodic system. The invention renders possible the production of aldehydes in a fair yield and at an adequate selectivity.
