Use of Hydrodynamic Cavitation to Intensify Solketal Synthesis from Glycerol and Acetone
摘要
Abstract
The possibility of using hydrodynamic cavitation to intensify solketal synthesis from glycerol and acetone in the presence of a zeolite has been shown for the first time. The reaction in the presence of faujasite zeolite (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 % (per loaded glycerol weight), and 25°C. The results show that the cavitation mode can be thought of as a promising method for intensifying glycerol ketal and acetal synthesis reactions.
