Kinetics and mechanism of thermal decomposition of hydroxylammonium perchlorate and its complex with hydroxylamine

Abstract

1. In its initial stages, the decomposition of hydroxylammonium perchlorate involves dissociation of the salt followed by decomposition of a complex of hydroxylamine with hydroxylammonium perchlorate. At elevated temperatures the reaction involving hydroxylamine molecules not bound into complexes plays an increasing part. 2. As hydroxylammonium perchlorate decomposes, the leading stage changes. The crucial reaction becomes oxidation of NH3OH+ by perchloric acid, leading to autocatalysis of the process.
