摘要
测定了甲乙酮 -水 -氟化钾体系在 40℃时的液 -液相平衡数据 ,用Pitzer理论和NRTL方程对液 -液相平衡数据进行了关联计算 ,计算值与实验值符合良好。采用氟化钾分离甲乙酮 -水体系 ,氟化钾的脱水率高达98.6 6 %
The liquid-liquid equilibrium data of methyl ethyl ketone-water-KF system were measured at 40℃. Using Pizer theory and NRTL equation, the above-mentioned data were correlated and calculated,and the results fit the experimental results well. The dehydration rate of KF is up to 98.66% using KF to separate the methyl ethyl ketone-water mixture.
