Reaction Conditions

Reaction Steps

61 g of benzoic acid were suspended in 200 ml of 1,2-dichloroethane. The suspension was heated to 40° C. following the addition of 38.6 g (0.60 mol) of 98% nitric acid. 63.5 g of 100% sulphuric acid were then added dropwise over a period of 2 hours at that temperature, followed by stirring for another 3 hours. After cooling to 20° C., the deposit was filtered off. The filter residue was washed four times with 4 × 25 ml of 1,2-dichloroethane and then with water, followed by drying at 90° C. 32.6 g (39% of the theoretical yield) of 3-nitrobenzoic acid were obtained in this way.
