The catalytic properties of the zeolite monolith based on Cs-BEA_nsh in the reaction of obtaining cyclic carbonate from styrene epoxide under CO2 pressure in the flow were studied. It is shown that at a temperature of 100 ℃, a pressure of 20 atm, a ratio of reagent/cat = 0.25 and a flow rate of 0.5 ml/min. It was established that the maximum yield of cyclic carbonate was 9% at 100% selectivity, and increasing the reaction temperature successively to 130 and 150 ℃ leads to an increase in the maximum yield of the target product to 32 and 67%, respectively. At the same time, at a higher temperature, the selectivity decreases to 92%. It was noted that with a further increase in the process temperature to 180 and 200 ℃, an increase in the conversion of styrene epoxide to 95% is observed, but the selectivity for the target product is significantly reduced, which leads to a decrease in yield to 55%.
