Reverse phase high performance liquid chromatography (HPLC) employing an acctonitrile/methanol/water (45/10/45) mobile phase has been used to separate and quantitate the stabilizaers para‐nitro‐N‐methylaniline, (pNMA) and 2‐nitrodiphenylamine, (2NDPA) and their derivatives in a mixed‐stabilizer cast double hase rocket propellant composition undergiong acceterated aging at 80°C adn 90°C. Quantitative measurements show that pNMA is converted almost cntirely into N‐nitroso‐pNMA during the carly stages of aging and that this derivative persists for the remainder of the aging period. 2NDPA, on the other hand, reacts more slowly to give both N‐nitroso and C‐nitro derivatives.
Die Adhision zwischen Explosivstoff und Binder und die AblBsung in energiereichen Materialien mit Nitramin-FullstoffenEs wird eine Review zur Problematik der schlechten Adhasion zwischen Explosivstoff und Binder bei energetischen Materialien mit Nitramin-Fullstoffen durchgefiihrt. Das Phanomen der Ablosung (dewetting) und seine Folgen wird diskutiert; ein Literaturbericht iiber spezifische Adhasionsverstarker fur Systeme mit RDX-Fullstoff wird gegeben.
L'adhCrence entre substance explosive et liant et les problkmes de dko-hCsion dans les compositions a base de nitraminesOn passe en revue les problkmes que pose I'adhCrence entre I'explosif et le liant dans les compositions contenant des nitramines. On discute le phCnom&ne de la dtcoh&sion et ses consCquences. Une Ctude bibliographique examine les agents susceptibles d'augmenter l'adhkrence dans les compositions contenant de l'hexoghe.
SummaryThe problems associated with poor explosive-binder adhesion in nitramine-filled energetic materials are reviewed. The phenomenon of dewetting and its consequences are discussed and a survey of the literature relating to specific adhesion promoters for RDX-filled systems is presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
