摘要 测定了常压下25℃时水-醋酸-甲基叔丁基醚-氯化钠体系液液相平衡数据.结果表明,加盐可以改善体系的液液平衡,有利于提高溶剂的选择性.分别采用Othmer-Tobias和Bachman方程对实验数据进行了关联,相关性系数均大于0.991,数据结果可靠. Liquid-liquid equilibrium data for the quaternary system water - acetic acid - methyl tertbutyl ether（MTBE）- NaCl at 25 ℃ have been measured under atmospheric pressure. The results show that adding salt to the system is beneficial to increase the selectivity of solvent. The experimental data were correlated by the equals of Othmer-Tobias and Bachman, respectively. All the linear correlation coefficients are higher than 0. 991.
