The possibility of using hydrodynamic cavitation to intensify solketal synthesis from glycerol and acetone in the presence of a zeolite has been first shown. The reaction in the presence of zeolite faujasite (FAU, SiO2/Al2O3 = 14.9) has been studied. It has been found that the use of hydrodynamic cavitation contributes to an increase in glycerol conversion from 35.2 to 66.8% within 30 min of reaction without changing the solketal selectivity at an acetone/glycerol molar ratio of 2.5, a catalyst loading of 1.6 wt % (in terms of the weight of loaded glycerol), and 25°C. The results have shown that the cavitation mode can be thought of as a promising method for intensifying glycerol ketal and acetal synthesis reactions.
