Preparation of 4-nitroacetanilide
100 g of acetanilide are dissolved in 167 ml of sulfuric acid contained in a round flask, the temperature not being allowed to rise above 40° C. The solution is cooled to 5-10° C with ice-water, and the cooled mixture of 44 ml of nitric acid with 28 ml of sulfuric acid is added very slowly. During the addition the reaction mixture is stirred and cooled in the ice-water, the temperature being kept below 15° C. After standing a short time, the nitration mixture is poured into about 10 liters of water containing several lumps of ice, when the 4-nitroacetanilide separates out, and is filtered, washed properly from acids, and dried. 4-Nitroacetanilide is further purified by crystallization from ethanol yielding 110-120 g of almost colorless needles with melting point 207° C. The side product 2-nitroacetanilide is removed by extracting with chloroform, in which the 2-nitroacetanilide is soluble.
