Effect of Air in the Thermal Decomposition of 50 wt.% Hydroxylamine/water

Abstract

This paper presents experimental measurements of the thermal decomposition reaction of 50 wt% hydroxylamine/water (HA) in an oxygen-free environment using an APTAC calorimeter. Overall kinetics, onset temperatures, heats of reaction, and energy release rates vs. temperature are presented. These results are compared with the corresponding data for HA decomposition reaction in air. This information is especially valuable for the design of HA storage facilities. Presented also are the gas-phase decomposition products measured by spectrophotometry for the HA decomposition reaction in air and a discussion of the HA decomposition mechanism.
