実験手順

Ml. 11.3 of fuming nitric acid (0.275 mole) in 96% H2SO4 (50 ml) was dropwise added under stirring at room temperature to 48 g of 1,3-dichloro-4-nitrobenzene (0.25 mole) in 96% H2SO4 (350 ml). The mixture was stirred for two hours, then poured into crushed ice. The separated solid was washed with cold water to neutrality, dried under vacuum and crystallized from ethanol (170 ml) to give the dinitro compound (A), 45.5 g, yield 76.8%, as yellow prisms.
