Gas phase safety-control conditions for epoxidation of allyl chloride with hydrogen peroxide catalysed by TS-1

The explosion limits of allyl chloride in different oxygen-nitrogen mixtures were investigated, and the operating margin of oxygen content in the gaseous phase of a reactor was discussed. The results of reaction temperature and oxygen content trials in the gas phase of the epoxidation of allyl chloride with hydrogen peroxide over a titanium silicate (TS-1) catalyst are presented. The trials were carried out under atmospheric pressure and in the presence of methanol as a solvent. The influence of the following technological conditions and parameters on the course of epoxidation was examined: catalyst concentration, molar ratio of ALC/H2O2, solvent concentration, and feeding method. The conditions and parameters at which the functions describing the process reached the optimal and safe values were determined.
