ABSTRACT:
A process for the catalytic oxidation of liquid cycloparaffins to oxidation products thereof is disclosed. In the process, partial oxidation products are formed by oxidizing the cycloparaffin with molecular oxygen-containing gas in the presence of an oxidation catalyst comprising two heavy metal compounds. The first heavy metal compound is a cobalt compound having ligands selected from dialkyl phosphate, dicycloalkylphosphate and alkylcycloalkylphosphate, optionally additionally combined with pyridine. The second heavy metal compound is a chromium alkanoate. A preferred catalyst is cobalt bis[di(2-ethylhexyl)phosphate] combined with chromium naphthenate.
