摘要

Abstract

The influence of nitric acid on the thermal stability of nitrobenzene was studied.The thermal behavior and chemical thermodynamic parameters of pure nitrobenzene and its mixtures with nitric acid were analyzed by utilizing a CALVET heat flux calorimeter

C80.The kinetic parameters of chemical reaction

such as activation energy

frequency factor and heat of reaction

were calculated based on the experimental data of C80.Based on these parameters and the Semenov thermal explosion theory

the self-accelerating decomposition temperature of samples was calculated and compared.A GCT gas chromatography-time of flight mass spectrography was used to analyze the thermal decomposition of pure nitrobenzene at high temperature.The thermal decomposition mechanism of nitrobenzene and its mixture with nitric acid was proposed.
