Title: A new method to predict activation energies of nitroparaffins
Authors: Keshavarz, M H
Issue Date: Dec-2009
Publisher: CSIR
Abstract: A novel relationship has been derived to predict the activation energies (Ea) of low-temperature non-autocatalyzed thermolysis of nitroparaffins through suitable combination of elemental composition. The new correlation of Ea is based on the experimental data using the isothermal monomethric method, which is useful method to examine the kinetics of thermolysis of energetic materials in vacuum. The new method uses the optimized number of carbon, hydrogen and oxygen divided by molecular weight of nitroparaffins to obtain a reliable correlation. The new correlation is a general relationship because it can be applied for various nitroparafifins as compared to previous method which uses oxygen balance for some specific groups of mentioned compounds. R-squared value or the coefficient of determination of the new correlation is 0.954.
