SO2-4/TiO2-La2O3, a novel solid superacid, was prepared and its catalytic activities at different synthetic conditions are discussed with esterification of n-butanoic acid and Bu alc. as probing reaction. The optimum conditions have also been found, mole ratio of n(La3+):n(Ti4+) is 1:34, the soaked consistency of H2SO4 is 0.8 mol/L, the soaked time of H2SO4 is 24 h, the calcining temperature is 480 °C, the calcining time is 3 h. Then it was applied in the catalytic synthesis often important ketals and acetals as catalyst and revealed high catalytic activity. Under these conditions on which the molar ratio of aldehyde/ketone to glycol is 1:1.5, the mass ratio of the catalyst used in the reactants is 0.5%, and the reaction time is 1.0 h, the yields of ketals and acetals can reach 41.4%∼95.8%. This study involved multiple reactions and reactants, such as Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate (cas: 6413-10-1SDS of cas: 6413-10-1).
Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate (cas: 6413-10-1) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Although benzodioxole is not particularly important, many related compounds containing the methylenedioxyphenyl group are bioactive, and thus are found in pesticides and pharmaceuticals.SDS of cas: 6413-10-1
