Silica-supported cerium (IV) sulfate [Ce(SO4)2/SiO2] solid acid catalyst was prepared by sol-gel and impregnation methods. The catalytic activities for condensation of Et acetoacetate with 1,3-butandiol were evaluated with the same condition. The effects of the calcination temperature of the catalyst, mass fraction of cerium (IV) sulfate, molar ratio of Et acetoacetate to 1,3-butandiol, mass fraction of Ce(SO4)2/SiO2 and reaction time were discussed in detail. It showed that Ce(SO4)2/SiO2 solid acid was more active than cerium (IV) sulfate tetrahydrate. The yield of fructone was more than 95.5% under the condensation conditions of calcination temperature of catalyst 500 degree, mass fraction of cerium (IV) sulfate 15.0%, molar ratio of Et acetoacetate to 1,3-butandiol 1:1.2, mass fraction of Ce(SO4)2/SiO2 in Et acetoacetate 7.5% and reaction time 120 min. The experiments also revealed that the Ce(SO4)2/SiO2 catalyst had good repetitious and reproducible stability. This study involved multiple reactions and reactants, such as Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate (cas: 6413-10-1Reference of 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. 1,3-Benzodioxole can be synthesized from catechol with disubstituted halomethanes.Reference of 6413-10-1
