with nitric acid in sulfuric acid;water;

Steps:

EXAMPLE 2 Preparation of N-(4'-nitrobenzoyl)-2,4-dinitroaniline

EXAMPLE 2 Preparation of N-(4'-nitrobenzoyl)-2,4-dinitroaniline 242 parts of N-(4'-nitrobenzoyl)-aniline are dissolved in 2000 parts of 66° Be sulphuric acid, then the solution is cooled to 0° C. Then a solution of 130 parts of nitric acid in 70 parts of 66° Be sulphuric acid is added in a period of 2 hours. The mixture is allowed to react for 1 hour at 10° C. then for 2 hours at 25° C., and this solution is then added slowly to 2000 parts of water and 3000 parts of ice. The product obtained is filtered off and washed with water to remove excess acid, and then dried. 329 parts of a product melting at 195° C. are obtained conforming to the information in the literature, and the yield is 90% by weight.
