用精密自动绝热热量计测定了配合物Zn(Val)SO4·H2O在78～373K温区的摩尔热容,通过热容曲线的解析得到该配合物起始脱水温度为327.05K.将该温区的摩尔热容实验值用最小二乘法拟合得到摩尔热容(Cp,m)对温度(T)的多项式方程,并计算了它的各种热力学函数.此外,用惰性气氛下的TG DTG及DSC对该配合物的热分解过程进行了研究.
The molar calorific value of complex Zn (Val) SO4 · H2O in the temperature range of 78 ~ 373K was determined by a precision automatic adiabatic calorimeter. The initial dehydration temperature of the complex was 327.05K by the analysis of the heat capacity curve. , The polynomial equation of molar heat capacity (Cp, m) versus temperature (T) was fitted by the least squares method and its various thermodynamic functions were calculated.In addition, TG DTG and The thermal decomposition of the complex was studied by DSC.
