摘要
通过对N甲酰吗啉(NFM)官能团的分析,将其划分为CH2,CNH2,CHO和CH2OCH2四个官能团,根据N甲酰吗啉溶液体系的实验数据对官能团的相互作用参数进行了拟合,并预测了含NFM的三元体系的汽液平衡数据及四种烃类在NFM中的无限稀释活度系数,并将其与已公开发表的三种划分方法预测数据进行比较。结果表明,划分方法较为合理,且应用UNIFAC基团相互作用参数拟合的误差结果较为满意。
Based on analysis of N-formylmorpholine(NFM) groups which is divided into four groups: CH_ 2, CNH_ 2, CHO and CH_ 2OCH_ 2. The interaction parameters of UNIFAC model are fitted and the vapor-liquid equilibrium(VLE) data of the ternary systems including NFM and the infinite dilution activity coefficients of four hydrocarbons in NFM are predicted. Comparison of the prediction results of other three published methods of group division for NFM indicated more satisfying results with the interaction parameters and division method.
