Abstract: Pentanitrotoluene is prepared by a method which comprises preparing an amdinitrotoluene from a precursor of either TNT or 2,5-dinitro-3-methylbenzoic acid, nitrating the aminodinitrotoluene to produce a nitramine intermediate, converting the nitramine intermediate to an aminotetranitrotoluene and oxidizing the aminotetranitrotoluene with peroxydisulfuric acid to pentanitrotoluene. Pentanitrotoluene is an explosive.

Abstract: A process is disclosed for converting aromatic thiols to the corresponding nitroso- or nitro-substituted compounds by treating the thiol compounds with an excess of nitric acid having a HNO3 concentration of 90 to 100 percent. Representative starting compounds are benzenethiols and pyridinethiols which, in addition to the thiol group, are substituted with one or more electronwith-drawing groups such, for example, as chloro, nitro or cyano, among others. The nitroso and nitro compounds produced during the reaction have utility as pesticides and are variously effective as herbicides and in the control of fungi and nematodes as well as of parasites infecting warmblooded animals.
