Tetranitroaniline expls

B. Fliirscheim patented the prepn of 2,3,4,6-Tetranitroaniline, one of the most powerful expls. It was used during WWI by the Germans and Japanese (Vol 1 of Encycl, pp A411 to A413)... 

N)3C6H(NH.C2H5)2 mw 299.24, N 23.41% yel crysts mp 142-44° was prepd by heating N-nitro-N-ethyl-2,3,4,6-tetranitroaniline with ethylamine in a tube at 50-60°, or from 3-chloro-2,4,6-trinitrophenol ethylamine in ale. Its expl props were not reported Refs 1) Beil 13, 61 8t (17) 2) J.J.
