Poyet, J. M. published the artcileAnalysis of stabilizers, plasticizers and impurities in explosives by liquid chromatography, SDS of cas: 1821-27-8, the publication is Symposium on Chemical Problems Connected with the Stability of Explosives, [Proceedings] (1977), 109-20, database is CAplus.
High-pressure liquid chromatog. (HPLC) has been used to determine nitroso and nitro derivatives of diphenylamine [122-39-4] and 2-nitrodiphenylamine [119-75-5] stabilizers in nitrocellulose [9004-70-0] and poly(vinyl nitrate) [26355-31-7] explosive powders. In the determination of diphenylamine derivatives, Microporasil was used as column packing and cyclohexane-1,2-dichloroethqne mixture as eluant. 2-Nitrodiphenylamine derivatives were estimated by inverse phase chromatog. on a Microbondapak C-18 1/4 column with MeOH-H2O (67.5:32.5) as eluant and (PhO)3PO as internal standard Trace amounts (0.01%) of RDX [121-82-4] in HMX [2691-41-0] also could be estimated on the Microporasil column with cyclohexane-dioxane-MeCN (63:34:3) as eluant.
