Versuchsvorschrift

Once the total amount of 2,4-dinitroaniline and the corresponding amount of chlorine gas--an equimolar amount and c. 10 % excess of this latter--have been added to the hydrochloric acid, the batch is allowed to react for half an hour to 1 hour and then excess chlorine is expelled with nitrogen. The product is isolated by filtration, washed until neutral and dried. The 2-chloro-4,6-dinitroaniline is obtained by this process in a yield of 95 % with a content of less than 0.5 % by weight of unreacted starting material (dinitroaniline).
