用氧化镁氯化镁水溶液制备了8水合氯氧化镁[nMg(OH)2·MgCl2·8H2O], 并测定了其在盐酸中的溶解热, 实验结果表明, 氯氧化镁溶解热与n值呈线性关系, 根据溶解热求出5Mg(OH)2·MgCl2·8H2O和3Mg(OH)2·MgCl2·8H2O的生成热分别为-7727.1和5888.1kJ·mol^1^-。

The heat of solution was determine by the Setaram C80 microcalorimeter. The heats of solution of 5Mg(OH)2.MgCl2.8H2O and 3Mg(OH)2.MgCl2.8H2O are derived from the linear relationship between molar ratio of MgO and MgCl2 and heat of solution; the heats of formation are calculated

Key words: STRUCTURAL ANALYSIS, MAGNESIUM OXIDE, SOLUTION HEAT, FORMATION HEAT, MAGNESIUM CHLORIDE
