Pyridine, tetramethyl guanidine, and hexamethylphosphoramide were evaluated as solvents for the microdetermination of two weakly acidic compounds of ordnance interest, 1,3,5-trinitro-1,3,5-triazacyclohexane and 1,3,5,7-tetranitro-1,3,5,7-tetrazacyclooctane. The titrant was tetrabutylammonium hydroxide in methanol/toluene. Endpoints were determined potentiometrically by a glass/modified calomel electrode system or by two polarized platinum electrodes. The largest endpoint break was found in the very basic solvent tetramethylguanidine. Endpoint detection using two polarized platinum electrodes significantly enhanced the precision of the anaysis. 4 figures, 2 tables.
