摘要: 用改进的Rose釜测定了水-N,N-二甲基甲酰胺(DMF)在101.33kPa、13.33kPa下的二元及水──DMF──甲酸在101.33kPa下的三元等压汽液相平衡数据.并对水──DMF汽液相平衡数据进行了关联,得出了相应的UNIQUAC,NRTL和Wilson模型参数.用Wilson模型推算了所测的三元汽液相平衡实验数据.结果令人满意.

Abstract: The vapor-liquid equilbria(VLE) data for a water-DMF binary system at 101.33 kPa、13.33 kPa and a Water-DMF-formic acid ternary system were measured by using an improved Roseequilibria cell. UNIQUAC,NRTL and Willson equation were used to correlate the water-DMF VLEdata.VLE data for water-DMF-formic acid system has been estimated by using Wilson equation.Theevaluation results all agreed well with experimental data.
