摘要
用改进的 Dvorak—Boublik 汽液平衡釜测定含甲酸,二甲基甲酰胺(DMF).水物系的 H_2O—HCOOH;HCOOH—DMF;H_2O—DMF 三对二元汽—液平衡数据和 HCOOH—DMF—H_2O 的三元汽—液平衡数据,并用 Wilson 方程和 NRTL 方程进行热力学关联,其中甲酸和缔合效应用双分子缔合模型进行研究,得到满意的结果。
The vapor-liquid equilibrium data for three pairs of two-compo-nent system,formic acid-water(H_2O-HCOOH),N.N-dimethyformamide-for-mic acid (HCOOH-DMF),N.N-dimethylformamide-water(H_2O-DMF)and a three-component system,formic acid-N.N-dimethylformanide-water(HCOOH-DMF-H_2O)are measured by using an improved DVORDK-Boublikequilibrium boiler.These data are interrelated by using Wilson and NRTLequations,in which the association effect of formic acid is studied by usingthe bimolecule model,obtaining satisfactory results.
