DETERMINATION OF THE THERMOLYSIS KINETIC PARAMETER OF THE COMPLEX OF β-ALKOXYCARBONYLETHYTIN TRICHLORIDES WITH THE SINGLET NON-ISOTHERMAL DSC CURVE
【摘要】 利用国产CDR - 4P型差动热分析仪测得DSC曲线 ,利用积分法和微分法逻辑选择确定了β_烷氧羰基乙基三氯化锡配合物热分解的最可几数学机理函数F(a) =[-ln(1-a) ]2 / 3 ;f(a) =3/ 2 (1-a) [-ln(1-a) ]1/ 3 ,从而计算出指前因子和活化能分别为logA =2 5 .6和E =2 83.4kJ/mol,logA =2 4 .7和E =2 78.6kJ/mol.
【Abstract】 The DSC curves were determined by the differential scanning calorimeter with the type of CDR4P.Choose logically with the integral method and differential method to determine the most probable mechanism function:F(a)=[- ln (1-a)] 2/3 ,f(a)=3/2(1-a)[- ln (1-a)] 1/3 .The preexponential factor and the activation energy were separately calculated: log A =25.6, E =283.4 kJ/mol;log A =24.7, E =278.6 kJ/mol.
