YieldReaction ConditionsOperation in experiment
With acetic anhydride; In water; acetic acid; EXAMPLE 3a Preparation of the mononitro-2,4-dimethylacetanilide isomer mixture 300 g (5.0 mols) of glacial acetic acid are initially introduced into a 1 l four-necked flask with a stirrer, condenser, dropping funnel and internal thermometer. 141 g of mononitro-2,4-dimethylaniline isomer mixture (prepared by nitration of 121 g=1.0 mol of 2,4-dimethylaniline) of the following composition: 90.2% by weight of <strong>[2124-47-2]5-nitro-2,4-dimethylaniline</strong>, 9.5% by weight of 3-nitro-2,4-dimethylaniline, and 0.3% by weight of 6-nitro-2,4-dimethylaniline are introduced into the flask at 20 C. 122 g (1.2 mols) of acetic anhydride are added dropwise to the mixture in the course of 1 hour, whilst cooling, and the temperature is not to rise above 55 C. The reaction mixture is then heated to boiling and is heated under reflux for 1 hour. 300 g is glacial acetic acid are then distilled off under normal pressure. The approximately 120 C. hot reaction solution is allowed to run into an initially introduced quantity of 1,500 g of water at 35 C., whilst stirring, and the temperature is not to rise above 60 C. The reaction mixture is cooled to 20 C., whilst stirring, and the precipitated product is filtered, washed with water until free from acetic acid and dried well under suction. Yield about 230 g of moist product with the relative composition given above.
