【摘要】 应用连续热力学方法，对实验测定的糖醛－提余油，糠醛－抽出油，Ｎ－甲基－２－吡咯烷酮－提余油，Ｎ－甲基－２－吡咯烷酮－抽出油在常压下的汽液平衡数据进行了关联。其中连续组分的分布函数Ｆ（Ｉ）采用Γ函数和样条函数，连续组分间的相互作用参数及离散组分（溶剂）和连续组分之间的相互作用参数作为常数处理，取得了满意的结果。并将连续热力学法与虚拟组分法作了比较，结果表明，前者不仅计算准确度高，而且计算效率大大提高。更多还原

【Abstract】 The VLE data determined at normal pressure for four systems of furfural-raffinate oil, furfural-extract oil,N-methyl-2-pyrrolidone-raffinate oil, N-methyl-2-pyrroli-done-extract oil were correlated by continuous thermodynamics method. The distribution functions for continuous component used a Γ function and a cubic spline function ,in this paper.And the interaction parameters between discrete component-continous component,and continuous component-continuous component are assumed to be constant.The results are satisfactory.By compared the continuous thermodynamics method with pseudo-component method ,we get the results that the former was not only more accurale in calculation,but also the efficient of calculation was highly raised.更多还原
