摘　　要：采用ＴＧ－ＤＴＡ技术，在Ｃｏａｔｓ－Ｒｅｄｆｅｒｎ积分式和Ｏｚａｗａ公式基础上，运用双外推法对固态草酸钴（Ⅱ）二水合物脱水过程进行分段处理，确定了各段最可能机理。Dehydration process of cobalt(Ⅱ) oxalate dihydrate in solid state was studied by double extrapolation method based on Coats Redferns integral equation and Ozawas equation. The dehydration of CoC 2O 4\52H 2O was described by two steps. The probable mechanisms of each step were determined. Furthermore, the corresponding kinetic parameters were obtained.
