Abstract
A cycloalkane is oxidised in the liquid phase at elevated temperatures and under elevated pressure to the corresponding mixture of cycloalkanone and/or cycloalkanol by means of a gas containing molecular oxygen. A dissolved metal salt is used as a catalyst and the reaction is carried out in the absence of a boric acid derivative. The water concentration of the cycloalkane to be oxidised is reduced before the latter is introduced into the oxidation reactor. Unconverted cycloalkane is removed from the reaction mixture and recirculated into the oxidation stage. The new process reduces the soiling of the reaction vessels and counteracts the occurrence of oxygen strikethrough.
