用热分析(TG/DTG)技术研究了固态水杨酸钙(Ca(H_4C_6OHCOO)_2·2H_2O)在空气中的热分解过程.热分析结果表明,Ca(H_4C_6OHCOO)_2·2H_2O在空气中分4步分解.用Friedman法、Flynn-Wall-Ozawa(FWO)法和ASTM E698法求取了Ca(H_4C_6OHCOO)_2·2H_2O(s)失水过程的活化能E,并通过多元线性回归法给出了可能的机理函数.
The thermal decomposition of calcium salicylate (Ca (H_4C_6OHCOO) 2 · 2H_2O) in air was investigated by TG / DTG method. The thermal analysis showed that Ca (H_4C_6OHCOO) _2 · 2H_2O was separated into 4 Step decomposition.The activation energy E of water loss of Ca (H_4C_6OHCOO) _2 · 2H_2O (s) was obtained by Friedman method, Flynn-Wall-Ozawa (FWO) method and ASTM E698 method, and was given by multivariate linear regression Possible mechanism functions.
