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%.
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% .
