• 製造方法

  Synthesis of 3-methyl-1-nitrobutane: Isopentyl bromide (120.84 g, 0.80 mol) was added dropwise to a mechanical stirred solution of sodium nitrite (110.39g, 1.60 mol) in DMF (500 mL) at 0°C. The reaction mixture was mechanically stirred overnight at room temperature. Water (1 L) was added to the mixture. The mixture was extracted with pet. ether (4 x 150 mL). The combined organic phases were washed with water (2 x 150 mL). The organic phase was dried with Na2SO4 then the solvent was evaporated under reduced pressure. Distillation under vacuum gave 30.2g (32%) of the colorless nitroalkane 3-methyl-1-nitrobutane (b.p. 58 - 60°C 21 mmHg)
