摘要
氟化钾的Pitzer参数适用于质量分数为 10 .4 2 %的氟化钾水溶液 ,当用氟化钾分离有机水溶液时 ,在 30℃时其饱和溶液的质量分数为 51.95% .因此 ,必须研究高浓度下氟化钾Pitzer参数的求解问题 .本文利用丙酮 水 氟化钾体系的相平衡数据以及由Pitzer理论和Wilson方程联合建立的数学模型 ,求解了高浓度下氟化钾的Pitzer参数 ,用丁酮 水 氟化钾体系及四氢呋喃 水
WT5BZ]Pitzer parameter of KF is applied to 10.42% aqueous solution of KF. When KF is used to separate organic/water mixtures, its concentration is up to 51.95% at 30 ℃. For this reason,the evaluation of Pitzer parameter of KF in high concentration solution must be studied. In this paper,using liquid_liquid equilibrium data of acetone_water_KF system and the mathematical model developed by Pitzer theory and Wilson equation, the Pitzer parameter of KF in high concentration is evaluated. The Pitzer parameter is reliable, because the experimental results of butanone_water_KF system and tetrahydrofuran_water_KF system are consistent with the theoretical prediction in permittable error range.
