  • Patent number: 4238415
    Abstract: An improved process for the preparation of cycloalkanols and cycloalkanones by the liquid phase oxidation of a cycloalkane having from 5 to 12 carbon atoms in the ring by means of a gas containing molecular oxygen to obtain an oxidation mixture containing cycloalkyl hydroperoxide and acids, and the subsequent decomposition of such cycloalkyl hydroperoxide to cycloalkanols and cycloalkanones. The decomposition is carried out by means of a metal salt in the presence of an aqueous solution of an alkali metal hydroxide. The improvement comprises a neutralization step wherein the acids contained in the oxidation mixture are first neutralized, forming a neutralized organic phase containing the cycloalkyl hydroperoxide, whereafter the neutralized organic phase is treated with a metal salt in the presence of an aqueous solution of an alkali metal hydroxide to decompose the cycloalkyl hydroperoxide and form an organic phase containing cycloalkanols and cycloalkanones.
