摘　　要：从三正丁胺粗品中浓缩提取了杂质N-异丁基-N,N-二正丁基胺(简称IDA),研究了在不同真空度下三正丁胺和IDA的二元气液平衡数据,并且用Wilson方程、NRTL方程、UNIQUAC方程对气液平衡数据进行了拟合计算,得出NRTL方程的关联效果最好,平均相对偏差(AAD)为11.9%。N-isobutyl-N,N-dibutyl amine as an impurity was extracted form crude tri-n-butylamine. The vaporliquid equilibrium data between tri-n-butylamine and N-isobutyl-N,N-dibutyl amine was studied under different degree of vacuum. The vapor-liquid equilibrium data were fitted to calculate by using Wilson equation,NRTL equation and UNIQUAC equation. The result of calculate showed that NRTL equation had the best correlation effect,and the average relative deviation was 11. 9%.
