Abstract:
A study is performed of the effect acid activation with 0.125–0.5 M Н2SO4, HCl, and HNO3 has on the physicochemical properties and catalytic performance of natural clay (the Mukhartalinskii deposit) containing 95% montmorillonite (MM). The rate and selectivity of the synthesis of solketal [(2,2-dimethyl-1,3-dioxolan-4-yl)methanol] from glycerol and acetone are shown to depend on the type of acid and its concentration. The yield of solketal and the increased rate of the reaction grow along with the concentration of acid, which correlates with the increase in the number of Brønsted acid sites. The effectiveness of the system diminishes in the order MM/HCl > MM/HNO3 > MM/H2SO4 as the surface acidity rises
