    摘要: In continuous preparation of tertiary-butyl hydroperoxide by the direct oxidation of isobutane in dense-phase reaction mixture at a pressure in excess of the critical pressure of the mixture, and under conditions relating to temperature and to oxygen and isobutane content of the mixture, improvement in selectivity to TBHP is realized by a process which comprises conducting a plurality of such oxidation reactions each in one of a series of dense-phase reaction mixtures by continuously introducing isobutane reactant into the first reaction mixture in the series, continuously introducing oxygen reactant into each reaction mixture of the series, and withdrawing a continuous flow from each mixture of the series and introducing this flow into the next mixture of the series, with the provision that the continuous flow withdrawn from the last mixture of the series is taken from the process as a TBHP-containing product mixture characterized by a conversion of the isobutane reactant of between about 3 and 25 percent.

    摘要: In the preparation of tertiary-butyl hydroperoxide by the direct oxidation of isobutane, the production of tertiary-butyl hydroperoxide, expressed as the quantity of the compound prepared per unit of reactor volume per unit of time, is enhanced by conducting the oxidation in a dense, supercritical phase reaction mixture at a temperature in excess of the critical temperature of the mixture, at a pressure in excess of the critical pressure of the mixture, and under conditions relating to composition of the mixture.
