Abstract

The catalytic action of platinum in the oxidation of cumene to cumene hydroperoxide has been studied at a temperature of 110–120 °C, a flow rate of the oxidizing air of 1.6 × 10 −2 m 3/kg s, a contact time of 60 to 360 min, and an initial content of the initiator (cumene hydroperoxide) from 2 to 5%. It has been established that platinum has a catalytic effect upon the process, which is markedly displayed at high temperature and for a long treatment of the raw material. The homogeneous initiator (cumene hydroperoxide) has a weaker effect upon the cumene oxidation in the presence of platinum than in the absence of a catalyst.
