摘要
使用 RD- 型量热计 -微机数据处理系统测量了 2 98.15 K下 L i Cl在不同组成 C2 H5 OH - H2 O、(CH3) 2 CHOH- H2 O混合溶剂中的溶解热。利用 Debye- Hückel第二极限公式计算了一定醇摩尔分率下的标准溶解热 ΔH∞s 。用 Pitzer(1980 )模型进行了关联。用 Desnoyers提出的公式计算盐在水 -醇中的焓离子对相互作用参数 h1
Heat of solution of LiCl C\-2H\-5OH H\-2O and LiCl (CH\-3)\-2CHOH H\-2O systems have been measured with \{RD I\} conduction calorimeter PC Data Acquisitor system at 298.15 K. The experimental values were correlated using the second Debye Hückel limiting law and the ion interaction model of Pitzer, and the standard molar enthalpies of solution of LiCl for fixed composition of the mixed solvents were obtained; Using the method proposed by Desnoyers, the enthalpy pair interaction coefficient was evaluated for LiCl in water alcohol binary solvents.
