Chen, Yuefang published the artcileSynergy of Al2(SO4)3 and H3PO4 in co-solvents converts starch to 5-ethoxymethylfurfural, Computed Properties of 539-88-8, the main research area is synergy Al2SO4 H3PO4 solvent starch ethoxymethylfurfural.
Efficient synthesis of promising biofuel 5-ethoxymethylfurfural (EMF) directly from starch was developed over a mixed-acid system composed of Al2(SO4)3 and H3PO4 in ethanol-DMSO co-solvent medium. The reaction proceeds through the depolymerization of starch to form glucose over Bronsted acidic H3PO4, which is then isomerized to fructose by Al2(SO4)3, a Lewis acid catalyst. The mixed-acid system then synergistically catalyzes the formation of EMF. At 170°C, 36.9%, 39.8%, and 34.7% yields of EMF can be captured from corn starch, amylose and amylopectin, resp. Moreover, the conversion of cellobiose and wood pulp cellulose produces 38.5% and 9.5% yields of EMF.
