Kinetics and Mechanism of Thermolysis of Mixtures of Ammonium Nitrate with Polynitro Compounds

摘要

Kinetics of heat release in thermolysis of mixtures of ammonium nitrate with bis(2,2,2-trinitro-ethyl)succinate,tetrakis(2,2,2-trinitroethyl)orthocarbonate,technical-grade trinitrotoluene and of the individual polynitro compounds was studied.The temperature dependences of the initial rates of the processes and the time required to attain the maximal rate were determined.A thermolysis mechanism of these mixtures was suggested and the dependence of the thermolysis rate on the properties of the polynitro compounds was accounted for.
