N-Methyl-2,4-dinitroaniline

In this synthesis aminomethane is treated with dinitrochlorobenzene to form N-methyl-2,4-dinitroaniline, which on nitration yields N-methyl-N, 2,4,6-tetranitroaniIine (tetryl) V (Refs 4,5 7). During WW II millions of pounds of tetryl were manufd by this process... 

Was prepd by nitrating N-methyl-N-phenyl-2,4-dinitroaniline with nitric acid (dl.49) (Refs 1 2). Its expl props are power by Trauzl Test 87% PA and FI (figure of insensitiveness) 92% PA (Ref 4). Hantzseh Opolski (Ref 3) also prepd the compd as well as its aci isomer, (OjNJjCgHj.N Hj-(NOj)a N.O.OCH3l violet crysts, mp 140-1° with decompn...

N,N DIPROP YL-4-TRIFLUORO-METHYL-2,6-DINITROANILINE (1582-09-8) Ci3HjsF3N304 Combustible solid (flash point >185 F/>85°C oc Fire rating 1). May react violently with barium, potassium, sodium. Incompatible with organic anhydrides, acrylates, alcohols, aldehydes, alkylene oxides, substituted allyls, cellulose nitrate, cresols, caprolactam solution, epichlorohydrin, ethylene dichloride, isocyanates, ketones, glycols, nitrates, phenols, vinyl acetate. Exothermic decomposition with maleic anhydride. May increase the explosive sensitivity of nitromethane. Reacts with nitroalkanes, forming explosive products. As a dinitroaniline derivative, the extremes of heat (do not store above 90°F/32°C), mechanical shock, and fnction might be... 

Direct PT-catalyzed methylation of 2-nitroanilines gives selectively N-monomethylated products. Methylation of 2,4-dinitroanilines and 4-nitroanilines does not proceed under these conditions as selective monomethylation (eq. 30). 

N,4-DinitrO N-methylaniline, bright yellow needles from benz, mp 142.5° (Ref 2) CA Registry No 16698-03-6. It is prepu by the alkylation of N,p-dinitroaniline with methyl iodide in alk soln (Refs 8 9). It is one compd isolated from aged NC propints stabilized with N-methyl-p-nitroaniline. Hollingsworth at ERDE examined the reaction of nitrogen dioxide with this stabilizer in order to elucidate the mechanism of the formation of the compds isolated. He found that after 7 days at 35°,. a good yield of N,4-dinitro-N-methylaniline was obtd and postulated that it arose from the oxidn of N-nitroso-4-nitroaniline (Ref 16)... 

Materials. 2, 3-dinitroaniline (8), -methyl-N, N-dimethyl-aniline (9), p-chloro-N, N-dimethylaniline (9), p-nitro-N, N-dimethylaniline (1 ), N-methyl-p-toluidine (11), p-chloro-N-methylaniline (11), N, 2, 4-trinitroaniline (12), 2, 4-dinitro-N-methylaniline (13), 2, 4-dinitro-N, N-dimethylaniline (13) and N, 2, 4-trinitro-N-methylaniline (14) were prepared by known methods. Spectroscopic grade nitromethane and methylene chloride were dried using a molecular sieve. The other substrates were either available from related studies or were purchased and purified by standard methods.
