Abstract
The data on liquid-phase oxidation of acylcyclohexanes by air oxygen in the presence of transition metals (Co, Cr, and Ni) naphthenates are presented. Their physicochemical, thermogravimetric, and spectral characteristics are examined. The introduction of cobalt naphthenate into the system leads to a significant drop in the yield of naphthenic acids, but the content of oxyacids increases significantly (more than 30 %), as established. To achieve the maximum yield of naphthenic acids, the optimum content of chromium naphthenate is 0.2, while that of oxy-naphthenic acids, cobalt naphthenate concentration is 0.3 mass %.
