摘要
在常压下测定了 H2O-DMF-HCOOH体系的汽液平衡数据并进行了热 力学关联计算,测定了三组二元体系和一组三元体系的汽液相平衡数据。用 Wilson方程和缔合模型进行了热力学关联,求得H2O,DMF,HCOOH之间 的 Wilson方程配偶参数。由二元配偶参数推算了 H2O-DMF-HCOOH三元体 系汽液相平衡数据,并与实验数据进行比较;其结果令人满意。
The authors have made the measurements of data of isobaric vapor-liquid equilibrium and thermodynamic correlative calculations for H2O-DMF-HCOOH system. Data of vapor-liquid equilibrium for three pairs of binary systems and a set of ternary system are measured. The correlations of interaction parameters of Wilson equation are given. Association effect is taken into account for the systems containing the formic acid.
