无水醋酸锌与无水草酸固相反应动力学的研究
The kinetics of the solid state reaction between Zn(CH3COO)2 and H2C2O4
摘要
Abstract
The solid state reaction between Zn(CH3COO)2 andH2C2O4 underisothermal condition was studied by TG. The reaction was described by two steps. Their kinetic expressions were obtained by treating the fraction α of conversion with different mechanism functions g(α ). The first step was carried out with a small α , its kinetic expression is (1－ α )－1/2=Ae－E/RTt where E=70.72 kJ/mol and A=4.43× 108 min－1; the second step was carried out with a large α , its kinetic expression is (1－2α/3)－ (1－α )2/3=Ae－E/RTt where E=122.7 kJ/mol and A=9.81× 1014 min－1.关键词
