摘要：
The influence of the technological parameters on the course of the epoxidation of methallyl alcohol (MAA) with 30 wt.% hydrogen peroxide over titanium silicalite catalyst Ti-MWW has been investigated. Experiments were performed under atmospheric pressure, and in the presence of methanol as a solvent. The effect of the parameters such as: temperature (20-60 degrees C), molar ratio of methallyl alcohol to hydrogen peroxide (1:1-5:1), methanol content (5-90 wt.%), catalyst content (0-5.0 wt.%) in reaction mixture, reaction time (5-300 min) and intensity of stirring (0-500 rpm) was determined The course of the process was described by the following functions: the selectivity of transformation to 2-methylglycidol (2MG) in relation to methallyl alcohol consumed, conversion of methallyl alcohol and selectivity of transformation to organic compounds in relation to hydrogen peroxide consumed.
