摘要

对甲醇／乙醇/水／NH_4NO_3四元体系中的有关含盐二元汽液相平衡数据进行了测定及关联．提出用化学滴定──色谱分析联合法确定含盐液相组成．关联所得的最佳参数用于该体系三元及四元汽液相平衡数据的预测，并与实验值作了比较．结果表明，预测值与实验值符合良好．

Abstract

The VLE data for salt-containing binary systems of ethanol／NH_4NO_3 and water/NH_4NO_3 were determined

and were correlated in order to get optimal binary parameters in NRTL model.It is proposed that the titration analysis-gas chromatographic analysis combination method can be used to determine the components in liquid phase for multicomponent salt-containing systems.Salt-containing VLE data for the temary systems of methanol／water／NH_4NO_3

ethanol/water/NH_4NO_3

and for the quaternary system of methanol/ethanol/water／NH_4NO_3 were detenrmined.The optimal binary parameters were used to predict the VLE data for the above-mentioned multicomponent salt-containing systems by Salt-Containing Local Composition Model

and the experimental VLE data were compared with the predicted results.The results shows that the VLE data agreed well with predicted data

and the SaltContaining Local Composition Model was suitable for predicting the VLE of salt-containing quaternarysystems.
