Synthesis of 2-chloro-5-nitrobenzenesulfonic acid

Preparation of 2-chloro-5-nitrobenzenesulfonic acid

Preparation of 2-chloro-5-nitrobenzenesulfonic acid

Preparation of 2-chloro-5-nitrobenzenesulfonic acid

To a mixture of 100 grams of p-nitrochlorobenzene and 100 grams of 100 % sulfuric acid is added, with stirring, 280 grams of oleum (25 % sulfur trioxide). The mixture is heated at 100-110° until the nitrochlorobenzene has disappeared, then poured into 300 grams of ice and 300 grams of water and salted out with 200 grams of sodium chloride. After 24 hours, the product is filtered off and pressed out, yielding about 280 grams of moist filter cake which is dried.
