title: One-pot synthesis of 5-hydroxymethylfurfural directly from starch over SO(4)(2-)/ZrO2-Al2O3 solid catalyst.
abstract: The synthesis of 5-hydroxymethylfurfural (HMF) directly from starch was studied in dimethyl sulfoxide-water. The effects of catalyst variation, reaction time, water content, catalyst loading and temperature on the reaction were investigated. The SO(4)(2-)/ZrO(2)-Al(2)O(3) catalyst was found to act as a bifunctional catalyst with high activity for both hydrolysis and dehydration of starch. HMF yield of 55% was obtained after 6h at 423K for the reaction of starch (the molar ratio of water to glucose in starch is 44/1) over the SO(4)(2-)/ZrO(2)-Al(2)O(3) catalyst, which bears high acidity and moderate basicity with Zr/Al molar ratio of 1:1.
