Abstract:
It has been shown that solketal can be synthesized from glycerol and acetone irradiation in the presence of montmorillonite (MM) modified with an aqueous solution of 0.25 mol/L of HCl (0.25M HCl/MM). The reaction has been studied in a methanol solution at an acetone/glycerol molar ratio of 2.45–7.53, a catalyst concentration of 1.2–2.8 wt % (based on glycerol weight), and 30–56°C. It has been shown that solketal is the major product with a selectivity of 96.1–99.2%. The maximum solketal yield of 91.3% with a 98.6% selectivity is obtained within 15 min of reaction at an acetone/glycerol molar ratio of 7.53, a catalyst loading of 2.3 wt % (based on glycerol weight), and 56°C. The catalytic properties of 0.25M HCl/MM in the reaction under microwave and thermal heating conditions have been compared. It has been shown that the solketal yield in the reaction under MW irradiation is 2 times higher than that in the process with thermal heating.
