• 外観

  白色～ほとんど白色粉末～結晶

• 説明

  2,3-Dimethyl-2,3-dinitrobutane (DMNB), a nitroalkane compound used as a propellant, foaming agent and explosives detector, is an important additive component in the manufacture of explosives, and the product has been used to develop a rapid square-wave voltammetry measurement protocol for tagging on unmodified carbon fibre electrodes (DMNB Explosives).

• 化学的特性

  white to off-white crystals or cryst. powder

• 物理的性質

  sublimes at room temperature

• 使用

  2,3-Dimethyl-2,3-dinitrobutane (DMNB) is an additive required for commercial plastic explosives. The product has been used to develop a fast, square-wave voltammetric measurement protocol of taggant (DMNB explosive) at an unmodified carbon fiber electrode. This protocol used a phosphate buffer solution at pH 7.0.

• 合成

  The synthesis of 2,3-dimethyl-2,3-dinitrobutane is as follows:

  Add 4.5 g (0.05 mol) of 2-nitropropane and 9 mL of a 6 mol/L sodium hydroxide solution to a 100 mL three-necked flask. The reaction was stirred magnetically for 0.5 h in an ice-water bath, and 4 g (0.025 mol) of liquid bromine was added dropwise to the flask using a constant pressure dropping funnel. After the dropwise addition was completed, 15 mL of absolute ethanol was added to thereto, and stirring was continued in an ice bath for 0.5 h. Then the ice bath was removed, the temperature was raised to 90℃, and the reaction was refluxed for 2 hours to stop the reaction. After the reaction liquid was naturally cooled to room temperature, a large amount of white solid precipitated, filtered, washed several times with absolute ethanol and distilled water, and dried under vacuum to obtain 40.13 g of white flake crystals. The yield was 91.2%.
