“…Although amine-type chemical sensitizers are infrequent in emulsions, one which has been used in some formulations is ethylenediamine dinitrate. Formation of a complex with zinc permits determination of ethylenediamine by IC at levels of about 1 ppm without interference from other monovalent cations and amines [24].…”

With advantages in cost, safety and ease of use, water gel/slurry and emulsion explosives are rapidly replacing traditional explosives. As a result, cap sensitive versions of each are increasingly encountered in criminal activity and a strategy for their identification and characterization is needed. A water gel/slurry explosive is essentially an aqueous solution of an inorganic oxidizer gelled with a carbonaceous gelling agent. Dispersion of fuel or additional oxidizer in the gel produces a slurry, the "water gel explosive" of co=erce. Added sensitizers enhance intiation to a detonator with particular compounds protected by patent and specific to a producer. When intact material is available for examination, sensitizer and other component identification characterizes the explosive type. Emulsion explosives, more efficient than gels, differ in that, emulsifying agents suspend droplets of aqueous oxidizer solution in an oil phase. Chemical sensitizers may be used in emulsion explosives but are less co=on than in slurry types. Most emulsions are sensitized by microspheres, tiny glass bubbles which both control density and provide "hot spot" initiation. Physical characteristics and composition of typical slurries and emulsions, combined with a systematic analytical approach, are used for the characterization and discrimination of intact gel/slurry and emulsion explosives.

“…Carboxylic acids and their salts may be determined by a spectrophotometric procedure after reaction with chloranil 0003-2700/84/0356-63R$01.50/0 © 1984 American Chemical Society in a dimethylformamide-methyl ethyl ketone solvent. Relative standard deviations for 12 monobasic and 4 dibasic carboxylic acids were 0.007-0.035 (89). Carboxylic acids have been determined by a gas chromatographic-mass spectrometric method after their conversion to the tert-butyldimethylsilyl derivative.…”
