EPA chemical substance information information provided by: ofmpeb.epa.gov (external link)
Use used as a pharmaceutical intermediate for preparation of furazolidone anti-infective drugs furazolidone, furacilin, furacilin,
was used for nitrofurazone production.
production method furfural is obtained by nitration and esterification. Add acetic anhydride to the reaction Pan, cool down to -5 ℃, add Dropwise mixed acid (nitric acid and sulfuric acid) of 1/5 of the amount of material, and then add Dropwise nitric acid and furfural (1:2 volume) at the same time the temperature of the mixed solution was controlled at about 0 ° C., the mixture was added for about 5-6h, and a portion of furfural was added dropwise. Then, the mixture was stirred for 1H, water and sodium carbonate solution were added, and the temperature was raised to 55-62 ° C. For 1H. The product was cooled to 15 °c, filtered, washed with water, and spin-dried to yield 85%.
