D-(-)-Fructose → 5-(Hydroxymethyl)furfural

Participants

Reaction Conditions

Reaction Steps

14.3 g of high-fructose maize syrup (containing 10 g of carbohydrate, wherein fructose is 9 g, 50 mmol) was put into a 250 mL round-bottom flask, and 10 g of Amberlyst 15 resin was added therein. Next, 100 mL of dioxane was put into the reactor, and stirred for 3 hours at 100° C. After the reaction, Amberlyst 15 was filtered, and then the reactant was washed and reactivated by processing with acetone for 3 times, with distilled water for 3 times, with 2N NaOH for 2 times, with distilled water for 2 times, with 3N HCl for 2 times, with distilled water for 2 times, and with acetonitrile for 2 times. Then, the reactant was dried and reused for the next reaction. As a result of the HPLC analysis on the yield rates of 5-hydroxymethyl-2-furfural obtained by reusing Amberlyst 15 resin, it could be seen that the activity of Amberlyst 15 was sustainable.
