SO3H-functionalized Bronsted acidic ionic liquids (BAILs) were synthesized and utilized as highly efficient catalysts for the production of fructone via the acetalization reaction of Et acetoacetate with ethylene glycol. In comparison with conventional H2SO4 and cation exchange resins, the BAILs such as triethyl(4-sulfobutyl)ammonium hydrogen sulfate ([BSEt3N][HSO4]) of strong acidity exhibited excellent catalytic activity. The effects of various parameters such as different BAILs, reaction temperature, catalyst dosage, and molar ratio of the reactants on the conversion of Et acetoacetate were investigated in detail. The exptl. results indicated that the catalytic performance of BAILs were closely related to their Hammett acidities. Moreover, it was found that [BSEt3N][HSO4] could be also recovered easily and used repetitively six times without obvious decline in activity and quantity. This study involved multiple reactions and reactants, such as Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate (cas: 6413-10-1Electric Literature of C8H14O4).
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.Electric Literature of C8H14O4
