Abstract : The rates of decomposition of hexanitroethane were determined in a number of solvents and as the pure solid in the temperature range of 60 to 100C. The products of reaction from the thermal decomposition of the solid are best represented by the equation: (NO2)3C-C(NO2)3 yields 3NO2 + NO + N2O + 2CO2. Decomposition of hexanitroethane (HNE) for the pure solid and in CCl4 proceeds by a first-order reaction; the specific firstorder rate constants are, for solid HNE, k = 10 to the 18.6 power exp(-38,9000/RT)/sec., and for HNE in CCl4, k = 10 to the 18.5 power exp(-37,800/RT)/sec. The rate of decomposition of hexanitroethane in n-haptane is 11.5 times faster, and in cyclohexane it is 23 times faster, than that of the pure solid at 85C. Based on the kinetic data and products of reaction, a mechanism for the decomposition process is proposed. (Author)
