用等温热重法和非等温热重法研究了Cu(CH3COO) 2 ·H2 O的脱水反应。等温热重数据由g(α) =A·exp(-E RT)·t和等转化率下的lnt=E RT +ln [g(α) A]进行拟合确定了活化能的大小及可能的动力学方程 ;非等温热重数据通过Coats Redfern法进行拟合 ,结合等温动力学拟合结果得到反应的积分动力学函数g(α) =1- (1-α) 1 3、活化能E =12 0 5kJ mol、指前因子A =1 872× 10 1 3s- 1 、动力学补偿效应方程lnA =0 2 999E - 5 2 5 2。
The dehydration reaction of Cu (CH3COO) 2 · H 2 O was studied by isothermal thermogravimetry and non-isothermal thermogravimetry. Isothermal thermogravimetric data were fitted by fitting g (α) = A · exp (-E RT) · t and lnt = E RT + ln [g (α) A] at equal conversion to determine the magnitude of the activation energy and The possible kinetic equations were obtained. The non-isothermal thermogravimetry data were fitted by the Coats Redfern method. The integral kinetic function of the reaction g (α) = 1- (1-α) 1 3 was obtained by fitting the isotherm kinetics. E = 12 0 5kJ mol, pre-exponential factor A = 1 872 × 10 1 3s-1, kinetic compensation effect equation lnA = 0 2 999E - 5 2 5 2.
