Reaction Steps
Netherlands Appln. No. 66-01366 (Chemical Abstract, Vol. 68 95548A) discloses a process for the preparation of 3-nitrobenzoic by adding anhydrous nitric acid to a mixture of benzoic acid and sulfur trioxide. After the addition is completed, the sulfor trioxide is evaporated to obtain a white solid which is recrystallized from a mixture of alcohol and water to obtain pure 3-nitrobenzoic acid, m.p. 141° C.
