Abstract

The reaction of liquid phase oxidation of isopropylbenzene in the presence of nitrogen-containing catalysts at 110–130 °C has been studied. It was found that with the use of N-hydroxyphthalimid and its 3- and 4-methyl-substituted analogs, there is achievement of the conversion of isopropylbenzene 40–50 % with selectivity of hydroperoxide isopropylbenzene formation ≥ 90 % within 2–2,5 hours. Taking into account the amounts of phenol production, the solution of the problem of isopropylbenzene oxidation with usage of N-hydroxyphthalimid by means of increase of the reaction speed and conversion of hydrocarbon together with keeping high selectivity of hydroperoxide, can considerably influence the economic indices of the process.
