摘    要:用改进的Rose釜测定了101.325 kPa下的醋酸-水-醋酸异丙酯、醋酸-水-醋酸异丁酯体系的汽液相平衡数据,并用UNIQUAC活度系数模型进行了关联研究。结果表明用UNIQUAC模型进行关联所得到的计算值均与实验值吻合较好。

关 键 词:醋酸  醋酸异丙酯  醋酸异丁酯  汽液平衡  UNIQUAC模型

Abstract:The VLE data of acetic acid-water-isopropyl acetate and acetic acid-waterisobutyl acetate systems were measured at 101.33 kPa with an improved Rose stilling, then UNIQAC model were used to correlate and predict these data by a Matlab functional program. It was observed that both the correlation and predictions by UNIQAC model were in good agreement with the experimental results.
Keywords:acetic acid   isopropyl acetate   isobutyl acetate   vapor-liquid equilibrium   UNIQUAC model  correlation
