摘要
Abstract
With the help of the initial temperature( To ), at which DSC curves deviate from the basline, the onset temperature( Te)and maximum peak temperature(Tp) from the non-isothermal DSC curves at different heating rates(β), the thermal decomposition activation energy( EK and EO ) and pre-exponential constant( AK ) obtained by Kissinger's method and Ozawa's method, the value of beo（orpo) from Hu-Zhao-Gao's equation and the value of ae0(0r po) from Zhao-Hu-Gao's equation, the values of specific heat capacity(Cp) obtained by microcalorimetry, density(p) and thermal conductivity(λ), the decomposition heat( Qd, taking half-explosion heat), Zhang-Hu-Xie-Li's formula, Hu-Yang-Liang-Xie's formula, Hu-Zhao-Gao's formula, Zhao-Hu-Gao's formula,thermodynamic relation formulae, Smith's equation, Friedman's formula, Bruckman-Guillet's formula, Frank-Kamenetskii's formula, Wang-Du's formulas and Yoshida's formulas, the values( Too, Teo and Tpo) of To, Te and Tp corresponding toβ→0, thermodynamic parameters of activation reaction( AG≠ 、AH≠ 、AS≠ ), thermal explosion temperature( Tbe0 and Tbp0 ) , adiabatic time-to-explosion( tTiad ) , 50％ drop height( H50 ) of impact sensitivity, critical temperature of hot-spot initiation( Tcr. hot-spot), critical ambient temperature of thermal explosion ( Tacr ) , safety degree ( Sd ) , thermal explosion probability ( PTE ), explosion potential ( Ep ) and shock sensitivity relative to m-dinitrobenzene ( Ss ) of 1 , 1＇-Dimethyl-5,5＇-azotetrazole monohydrate ( 1, 1 ＇-DMATZ) and 2,2＇Dimethyl-5,5＇-azotetrazole(2, 2＇-DMATZ) are calculated. The results show that( 1 ) 1, 1 ＇-DMATZ is thermally stable; (2) the heat-resistance ability of 1 , 1 ＇-DMATZ is better than that of 2, 2＇-DMATZ; (3) the different positions of the methyl group in the molecules are the principal factor affecting the thermal safety.关键词
