1-Methyl-3-butylimidazolium decatungstate ([C8H15N2]4W10O23, [Bmim]4W10O23) was prepared from 1-butyl-3-methylimidazolium bromide and sodium tungstate in hydrochloric acid solution. With the use of [Bmim]4W10O23 as the catalyst and 50% H2O2 as the oxidant, 3,4-dinitrofurazan (, DNF) was synthesized from 3,4-diaminofurazan (, DAF) in concentrated H2SO4. At a temperature of 35 °C, this process significantly increased the DNF yield from 39% to 58%, when compared with that with the conventional Na2WO4·2H2O catalyst under the same conditions. The effects of catalyst, reaction time, and temperature were investigated. A maximum DNF yield of 58% was obtained under optimal reaction conditions: 0.03 g of [Bmim]4W10O23, H2O2/H2SO4 molar ratio of 1.5:1, temperature and reaction time of 35 °C and 210 min, respectively.
