With the help of the condensed formula CaHbNcOd,formula mass(M), initial density (ρ), standard molar enthalpy offormation (ΔfHθm), specificheat capacity (Cp), autoignition temperature (Tig), critical temperature ofthermal explosion (Tb), detonation decomposition reaction equation, expressionsdescribing the number of moles of gaseous detonation products per gram ofexplosive (N), the average mass of these gases (Mg) and the chemical energy ofthe detonation reaction per gram of explosive (ie heat of detonation)(Qd=-ΔdHθm), Kamlet-Jacobs equations ofcalculating the detonation velocity (D) and detonation pressure (P), andformulae of calculating the standard internal energy of formation ΔfEθ,ignition enthalpy(Hi), detonation reaction energy ΔdUθm, polytropic exponent k and particle velocity of detonationproducts (up,d), the values of the parameters Qd, ΔfEθ, Hig, ΔdUθm, D, P, k and up,d of evaluating the energy and damage effect ofexplosives were obtained.
