12-Tungstophosphoric acid was supported on SBA-15 and amine-modified SBA-15 by impregnation. The structure and properties of the catalyst were characterized by FT-IR spectroscopy, X-ray diffraction, N2 adsorption-desorption, TEM, Raman spectra and NH3-TPD technol. The result confirmed the mesostructure for SBA-15 and the Keggin structure of the heteropolyanions was preserved. However, aggregation occurred in the high loading, and because of the pore blockage, the BET surface area, pore volume and pore diameter decreased obviously. The tungstophosphoric acid can disperse in the pore of the support SBA-15/NH2, but the acidity of the catalyst reduced. The catalytic activities of the catalysts were evaluated for the esterification reaction of Et acetoacetate and ethylene glycol and the catalysts supported on amine-modified SBA-15 show excellent reusability and selectivity. This study involved multiple reactions and reactants, such as Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate (cas: 6413-10-1Synthetic Route 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. Although benzodioxole is not particularly important, many related compounds containing the methylenedioxyphenyl group are bioactive, and thus are found in pesticides and pharmaceuticals.Synthetic Route of C8H14O4
