Abstract

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.

## Abstract The HPLC determination of the stabilizers para‐Nitro‐N‐methylaniline (pNMA) and 2‐Nitrodiphenylamine (2NDPA) and their derivatives in two mixed‐stabilizer cast double base rocket propellants undergoing accelerated aging at 80°C and 90°C has led to the conclusion that N‐nitroso derivativ
