During the reaction a temperature of 70°C is maintained. After all the tetranitro-diphenylamine has been added, the reaction mixture is heated to 90°C, kept at this temperature for one hour, cooled down to room temperature and filtered on a vacuum filter. A yellow crystalline, easily filterable product is obtained. The spent acid is approximately of the following composition ...

Can be prepd by heating 2,2, 4 -trinitro-4-methyl-diphenylamine on a steam bath with coned HNOsCdl.42) (Ref 2). Its expl props were not examined... 

Differential pulse polarograms for a number of nitroso and nitro diphenylamine derivatives are shown in Fig. 18. Each nitroso and nitro group will give one peak, and derivatives with several groups will give one peak per separate group. Even 2,4,4 ,6-tetranitro diphenylamine will give four well defined separate peaks.
