Abstract

A process for oxidizing a cycloalkane, includes contacting a gas with a starting mixture, to form a product mixture, where the starting mixture contains (i) a cycloalkane, (ii) boric acid, and (iii) cobalt. The gas contains oxygen, the cycloalkane has 9 to 16 carbon atoms, and the product mixture contains a cyclic alcohol. The reactor output is increased by adding the cobalt salt, so that it is possible to lower the temperature, which decreases the rate of parallel and secondary reactions.
