热分析法测定化学反应热效应

The Study of CaC_2O_4·H_2O Heat Decomposition Process

摘要: 在不同气氛(He、O2)条件下,测定了草酸钙(CaC2O4.H2O)的热分解过程.用DSC峰面积确定了反应CO+1/2O2→CO2的热效应,与文献值比较,相对误差δ=-2.17%.

Abstract: The Calcium oxalate(CaC2O4 ·H2O)heat decomposition process is determined under various atmosphere(He,O2)and at raising temperature β= 10 ℃ ·min-1.The heat effect of the reaction CO+1/2O2 →CO2 is calculated based on its DSC top area with an error is-2.17%.
