Thin-layer chromatog. is applied to ascertain changes in composition of explosive stabilizers such as Ph2NH occurring during storage. Ph2NH can undergo nitration, the NO2 groups coming from the slow decomposition of explosives, such as nitroglycerine (I) and (or) nitrocellulose. The explosive is chromatographed on a SiO2 gel column followed by elution with a 5:3:2 by volume mixture of C6H6, CCl4, and 1,2-dichloroethane. The Rf values of many NO2 derivatives of Ph2NH are given. Identification of the eluted compounds can be accomplished by color, reaction with color-producing reagents, and by characteristics fluorescence in uv light. It is also possible to extract selectively from the explosive the Ph2NH derivatives only by using CH2Cl2 as solvent. Thin-layer chromatog. can be successfully used to determine the presence of other explosive-powder stabilizers, such as Akardit I and II, Centralite I and II, and Et phenylurethane. In such analysis, a 30:70 mixture of iso-Pr2O and petroleum ether is used as eluant. The same solvents must be used to detect dinitrotoluene (II) in the presence of I and Ph2NH. During elution with the above solvent mixture, I hardly moves, in contrast to Ph2NH and II. Intensive decomposition of a stabilizer can originate from poor compatability between the explosive and the storage material. Also for such cases, thin-layer chromatog. is applicable. The chromatog. method can be extended for obtaining quant. results through reference curves shown in the original and obtained by plotting extinctions vs. concentrations of substances such as Ph2NH and its derivatives 26 references.
