Methyl picrate = trinitroanisol

Introduction of Obermiiller Stability Test which consists of heating 1 to 2g NC in a small tube under vacuum at 135—140° and measuring the pressure of evolved gas by vacuum manometer (Ref 38a, pp 87—88) 1904—1905. 2,4,6-Trinitroanisole or Methyl Picrate was patented for use in smokeless proplnts in mixt with an equal amt of Pyrocellulose (Vol...

Trinitroanisol may also be prepared by the interaction of methyl iodide and silver picrate, and by the nitration of anisic acid, during which the carboxyl group is lost, but the most convenient method appears to be that of Jackson70 and his collaborators by which a methoxy group is substituted for chlorine in a nucleus already nitrated. A methyl alcohol solution of picryl... 

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...
