The synthesis of fructone from Et acetoacetate and ethylene glycol using fly ash modified by ammonium persulfate as solid acid catalyst was investigated. Various reaction parameters such as reaction time, ratio of Et acetoacetate to ethylene glycol, catalyst amount and water-carrying reagent amount were studied. The optimum reaction conditions were as follows: the molar ratio of Et acetoacetate to ethylene glycol 1:1.8, the quantity of catalyst 1.5 weight% by weight of Et acetoacetate, amount of cyclohexane 15 mL, and the reaction time 3 h. Under this optimum condition, the yield of fructone reaches 95.9%. The exptl. results showed that fly ash modified by ammonium persulfate was an excellent catalyst for synthesis of fructone. Compared with other acid catalysts, the sulfonated activated carbon has higher activity, less used quantity and reusability. This study involved multiple reactions and reactants, such as Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate (cas: 6413-10-1Category: dioxole).
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. Dioxole functionalized metal-organic frameworks have also been recently reported.Category: dioxole
