Ethyl picrate

Trinitro-N-methylaniline (N-methyl picra-mide), yellow needles from EtOH contg acid, mp /l4.8° (Refs 4 7) the UV spectrum has a peak at 340 and a shoulder at 410—20m (Ref 19) CA Registry No 1022-07-7. It is prepd by the hydrolysis of the N nitroso compd (see below) at 70—80° (Ref 5) by the action of coned sulfuric acid (Ref 8) or UV light (Ref 12) on Tetryl by the action of methyl amine on Ethyl Picrate (Ref 18) or Tetryl (Ref 7) or by the action of nitric acid (d 1.42g/cc) at 0° on N,N-dimethylaniline (Ref 10). It is present in crude Tetryl and is the active der-matitic agent in the latter (Ref 12). It can be isolated from crude Tetryl and identified by thin layer chromatography (Ref 21)... [Pg.119]

There is a great deal of evidence for the mechanism we shall discuss only some of it.2 Probably the most convincing evidence was the isolation, as long ago as 1902. of the intermediate 2 in the reaction between ethyl picrate and methoxide ion.4 Intermediates of this... [Pg.642]

Trinitrophenetol or ethyl picrate, m.p. 78°, is prepared by the same methods as trinitroanisol. The explosive properties of the two substances have been studied by Desparmets and Calinaud, and by Desvergnes,72 who has reported the results of the earlier workers together with data of his own and discussions of methods of manufacture and of the explosive properties of mixtures with picric acid, ammonium nitrate, etc. Drop test with a 5-kilogram weight were as follows ...

Gazzolo (1900) thought that the intense colours produced from alkyl picrates and alkoxides could be best described by the quinonoid structure 1 (R = R = alkyl). The first strong chemical evidence that this was indeed the case was provided by Meisenheimer (1902). He obtained identical compounds by the addition of potassium methoxide to 2,4,6-trinitrophenetole and potassium ethoxide to 2,4,6-trinitroanisole. Acidification produced in each case a mixture of methyl and ethyl picrates. This led Meisenheimer to the conclusion that these compounds... [Pg.212]
