Abstract:
The compatibility of nitronium perchlorate with various organic materials, including a solid propellant binder system, has been investigated. Infrared and electron paramagnetic resonance spectroscopy were employed to measure reactivity. The results indicate compatibility between raw NP and the system to be less than satisfactory. Studies of simple hydrocarbons gave the following results. Hexane, n-pentane and isooctane react slowly with NP, at ambient temperatures HNO3, NO2Cl, N2O and CO2 are major reaction products. Methane does not appear to react. Ethane, propane and neopentane are not detectively consumed by NP, but nitric acid is generated in small quantities along with perchloric acid. It has been tentatively concluded that the latter substances react very slowly with NP. Chlorine dioxide is inherently present at low concentrations in dry, commercial NP. Concentrations are slightly higher in undried NP. Addition of NP to water, NOClO4, HNO3, H3OClO4, and all tested organic substances except methane resulted in increased ClO2 concentrations. Two samples of Reta-coated NP contained higher than normal concentrations of ClO2. One concludes generally that NP is slightly unstable at ambient temperatures, that substances inherent in NP enhance the instability, and that added foreign substances promote ClO2 formation. The formation of ClO2 can be used as a qualitative measure of the reactivity of organic materials. Author
