Abstract

A very efficient method with respect to the reaction velocity as well as selectivity is proposed for the preparation of .alpha.-tetralone by the liquid phase oxidation of tetralin with oxygen, in which a binary catalyst is employed which is composed of a compound of chromium or cobalt soluble in the reaction mixture and an N,N-dialkyl substituted carboxylic acid amide such as N,N-dimethylformamide, N,N-dimethylacetamide and the like.
