OXIDATION OF SULFUR-COMPOUNDS OF PETROLEUM TO SULFONES UNDER FOAM-EMULSION CONDITIONS

A study has been made of the hydrogen peroxide oxidation of sulphur co mpounds in diesel fraction and also a sulphoxide concentrate to sulpho nes under foam-emulsion conditions in the presence of acids. It has be en established that, when a mixture of sulphuric and acetic acids is u sed, the sulphone content of the oxidate is higher than in the presenc e of each of the acids separately. It has been shown that, with the fo am-emulsion oxidation of sulphoxide concentrate, the duration of the r eaction is shortened by a factor of 20 and the viscosity of the sulpho nes produced is lower by comparison with oxidation in a reactor with a mechanical stirrer.
