Assay of 1-ammonium-3,5-dinitro-1,2,4-triazole and its determination in mixtures with ammonium nitrate. [Titrant - cetylpyridinium chloride]
Work is in progress at this Laboratory on the detonation calorimetry of ammonium dinitrotriazole (ADNT) and mixtures of ADNT and ammonium nitrate (AN). Our analytical requirements were therefore, twofold: (1) the assay of ADNT, and (2) the determination of ADNT in admixture with AN. The first requirement was straightforward and was accomplished by nonaqueous titration of ADNT, either as an acid or as a base. The second requirement, however, proved more difficult. It was accomplished by using cetypyridinium chloride (CPC), a new titrant recently introduced at this Laboratory to determine the ADNT in the mixture. Various liquid-membrane electrodes such as the fluoroborate, perchlorate, and nitrate ion-selective electrodes (ISE's) may be used as endpoint sensors. We have found that the solid-state cyanide (or iodide) ISE also senses the endpoint of this titration, although considerably smaller endpoint breaks are obtained. Nevertheless, the mean values obtained using the fluoroborate and cyanide ISE's differed by only 0.09%. The method can also be used for the assay of some ammonium salts of other nitroheterocycles. It cannot differentiate, however, between the various compounds.
