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。
The kinetic behavior of dehydration process was studied by differential scanning calorimetry (DSC-1 1 1) using chlorite as raw material in Chaerhan Salt Lake in Qinghai Province. The dehydration temperature, activation energy, frequency factor and reaction order of each dehydration reaction are given. These parameters are similar to the dehydration of pure bischofite. However, the dehydration reaction series obtained in this experiment is about 0.5.
