KCI从水到二氧六环—水混合溶剂迁移焓的研究

本文测定了298.15k时KCl在40.01％,48.38％,55.43％和62.72％二氧六环——水混合溶剂中的标准溶解热,利用KCl在纯水中标准溶解热的文献数据得到了该盐从水到上述各混合溶剂的迁移焓。同时,就这一热力学量作了理论计算,证明用Bom效应修正过的定标粒子理论可以得到满意的结果。

KCl从水到二氧六环—水混合溶剂迁移焓的研究

In This paper, the standard heat of solutions of kcl dissolved in mixture solvent of dioxane—water at 40.01%, 48.38%, 55.43% and 62.72% has been determined at 298k. By using the literature data of the standard heat of solution of kcl in pure water, the transfer enthalpy of this salt from water to the mixture solvent mentioned above has also been obtained. To take theoretical calculation on this thermodynamic quantity, it isverified that the theory of scaled particle mo dified by Born effect may give satisfactory results.
