Abstract:
A process for oxidizing a cycloalkane, comprising:at the beginning of the oxidation, reacting (i) a cycloalkane having 9 to 16 carbon atoms, (ii) 0.2 to 5% by weight of boric acid, based on the amount of cycloalkane, and (iii) 0.05 to 5% by weight of cobalt (II), based on the amount of cycloalkane, with an oxygen-containing gas to oxidize the cycloalkane; adding additional boric acid to the reactants to complete the addition of boric acid during the oxidization reaction which occurs so that in the termination phase of the oxidation reaction the molar ratio of cyclic alcohol product to boric acid in the product mixture obtained ranges from 1:0.6 to 1:1.7; and obtaining a product mixture containing cyclic alcohol product.
