示差扫描量热法研究水氯镁石脱水过程的动力学

Study of Kinetics of the Dehydration Process of Bischofite by DSC

以青海察尔汗盐湖湖产水氯镁石为原料 ,利用示差扫描量热仪DSC -1 1 1研究了其脱水过程的动力学行为。给出了各脱水反应的脱水温度、活化能、频率因子以及反应级数。这些参数与纯水氯镁石脱水过程相近。但是 ,本试验所得的脱水反应级数约为 0 .5左右。

Using bischofite produced from Qinghai Chaerhan Salt Lake as the experimental material,we have studied its kinetics behaviors by DSC during the dehydration process.The kinetics parameters of each dehydration reaction,such as dehydration temperature,active energy,frequency factor and reaction order are examined.These parameters are close to the parameters of pure bischofite.But the reaction orders obtained in this experiment are about 0.5.
