摘　　要：在298.150 K下,利用具有恒温环境的溶解反应热量计测定了不同浓度的InC l3摩尔溶解热(ΔsHm),根据P itzer理论得到了InC l3的无限稀释摩尔溶解热(ΔsHm∞),和P itzer焓参数(βM0X)L及β(M1)XL,计算了溶质的偏摩尔焓.讨论了离子和溶剂之间的相互作用.利用文献中的InC l3的晶格能和氯离子的水化热数据,得到了InC l3和铟离子的水化热.The molar solution enthalpies of scattered metal compound InCl3 with various molalities were determined at 298. 150 K in water by the solution reaction isoperibol calorimeter. According to Pitzer＇s electrolyte solution theory, the molar solution enthalpy of InCl3 at infinite dilution, △sHm^∞, and Pitzer＇s parameters βMX^（0）L and βMX^（1）L were obtained. Then the values of apparent relative molar enthalpy Фr, hydration heat and relative partial molar enthalpy of solute（ InCl3 ）, L2, were calculated, respectively. At last, the interaction of InCl3 with water was discussed. In terms of the crystal lattice energy of InCl3 and the hydration heat of Cl^-, the values of the hydration heat of InCl3 and In^3＋ were obtained.
