Thermal Analysis Kinetics and Thermodynamics of 1,3-diglycidycalix [4] arenes

用热重TG和DSC对—叔丁基杯[6]的热分解过程进行了研究,用“DSC—TG”结合法推断出了对—叔丁基杯[6]热分解的可能过程,求出了其热分解反应动力学方程及热分析动力学参数;其最概然机理函数为21号,为一级反应过程。表观活化能为101.79 KJ.mol-1,指前因子的对数为51.64 S-1。

After a study of the thermal decomposition of calizarene by TG and DSC, the reasonable decomposition process is deduced by ＂DSC -TG＂ methods, and the possible decomposition kinetic equation and thermal analytical kinetic （parameters） are deduced as well. The most probable mechanism function is the 1th - type function, whose activation energy is 101.79 KJ. mol^-1 and whose pre- exponential factor is 51.64S^-1 .
