The results of the epoxidation of methallyl chloride (MAC) have been presented. The epoxidation was carried out in the autoclave with 30 wt % hydrogen peroxide in the presence of methanol as the solvent. Titanium silicalite Ti-Beta was used as the catalyst. The influence of the following parameters: temperature (20 - 120°C), the molar ratio of MAC/H2O2 (1:1-5:1 mol/mol), solvent concentration (methanol 5-90 wt %), catalyst concentration (0.1 - 5.0 wt %) and the reaction time ( 0.5 - 5 h ) on the yield and the selectivity of transformation to 2-methylepichlorohydrine and methallyl chloride conversion was investigated. The main product of the epoxidation was 2-methylepichlorohydrine, whereas 1-chloro-2-methyl-2,3-propanodiol was formed as a by-product.
