摘要
由１，３─丁二烯／ＤＭＦ和１─丁烯／ＤＭＦ二元物系汽液平衡数据，修订了ＣＨ＿２／ＤＭＦ和Ｃ＝Ｃ／ＤＭＦ两对ＵＮＩＦＡｃ基团交互作用参数值，并以此关联了Ｃ＿４─ＤＭＦ物系的全部Ｗｉｌｓｏｎ方程参数。经应用于丁二烯萃取精馏装置全流程模拟，证明所修订参数的准确度高，通用性强。
Based on the experimental vapor-liquid equilibrium data of 1,3-butadiene-DMF and 1-butene-DMF, the UNIFAC group interaction parameters for two pairs of group including CH_2/DWF and C=C/DMF are revised. On this basis, all parameters of Wilson equation for C_4-DMF system are correlat-ed. Larger range of applicabllity and higher accuracy of the parameters are proved by simulation re-sults for a butadiene plant.
