摘要
对α-萘乙酸(C_(12)H_(10)O_2)的热分解机理进行了研究,采用TG曲线确定了它的热分解过程,并通过四种方程对其热分解过程的活化能En进行了计算,利用41种不同的机理方程af)((微分机理方程)和G(α)(积分机理方程),对其热分解过程的非等温动力学数据进行了线性回归处理,并推断出其热分解机理为n=1/4的化学反应机理,最可几函数为4/3af-=)1(4)(a,并建立了其动力学方程。
The thermal decomposition mechanism of α-naphthylacetic acid（C_（12）H_（10）O_2）was studied. The thermal decomposition process was identified by TG-DTG technique. The activity energy Ea in thermal decomposition process was calculated by four kinds of equations. 41 Kinds of different mechanism equations including af）（（differential mechanism equation） and G（α）（integral mechanism equation） were used to treat the non-isothermal kinetic data in the thermal decomposition process with linear regression. The thermal decomposition mechanism was inferred as n = 1/4 chemical reaction mechanism. The most probable function was 4/3af established.
