From furfural by nitrification, esterification. Add the acetic anhydride into the reaction pot, cool down to -5℃, drop 1/5 of the added amount of mixed acid (nitric acid and sulfuric acid), then drop the mixture of nitric acid and furfural (1:2 volume) at the same time, control the temperature at 0℃ left Chemicalbook right, add about 5-6h, continue to drop a part of furfural. Then, stir it for 1h, add water and sodium carbonate solution, raise the temperature to 55-62℃, and keep it warm for 1h. Cooled to 15℃, filtered, washed with water, and then dried, the finished product was obtained with yield of 85%. Used as pharmaceutical intermediates, used in the preparation of furan anti-infective drugs, such as Lilitralin, furacillin, furantine, etc.
