摘要
通过碳酸化反应对Ｍｇ（ＯＨ）２中残余氯的溶出动力学进行了研究，得到两种显著不同的表观活化能，可定量、简便地确定杂质氯的存在形式，为氯化镁溶液通氨法生产试剂级Ｍｇ（ＯＨ）２工艺条件的选择提供了理论依据。
The dissolution kinetics of residual chlorine in Mg (OH)2 was studied by carbonation reaction and two different kinds of apparent activation energy were obtained. It can determine the state of impurity chlorine quantitatively and simply, thus providing a theoretical basis for the selection of technological conditions to manufacture reagent grade Mg (OH)2 by passing ammonia through magnesium chloride solution.
