摘要： 研究杯[4]芳烃的热解过程与性能参数，计算表观活化能，求解主降解过程的热解动力学函数方程。研究表明，空气气氛下杯[4]芳烃发生氧化燃烧，稳定性下降；Kissinger方法和Flynn-Wall-Ozawa（FWO）方法计算表观活化能分别是89.72、101.33 kJ/mol；热解机理函数方程是g(█(α))= [-ln(1-█(α))]2/3，反应级数n=2/3，非等温热解机理为随机成核和随后生长反应。

Abstract: The pyrolysis process and performance parameters of Calix[4]arene in air atmosphere were studied. The apparent activation energy of Calix[4]arene was calculated. The pyrolysis kinetic function equation of main degradation process was solved . The results showed that calix[4]arene was oxidized and combusted in air atmosphere, and its stability decreased. The apparent activation energies of Calix[4]arene are 89.72 kJ/mol and 101.33 kJ/mol by using the Kissinger method and Flynn-wall-Ozawa method, respectively. The pyrolysis mechanism function equation is g (█(α)) = [-ln(1-█(α))]2/3, the reaction order is n=2/3. The non-isothermal pyrolysis mechanism is random nucleation and subsequent growth reaction.
