摘要
用改进的Dvorak-Boublik平衡釜测定含甲酸、二甲基甲酰胺(DMF)、水体系的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,其中甲酸的缔合效应用双分子缔合模型进行研究,得到令人满意的结果。
The vapor-Liquid equilibrium data for three binary systems, formic acid-water (HCOOHH_2O), N. N-dimethylformamide-formic acid (DMF-HCOOH). N. N.-dimethylformamide-Water (DMF-H_2O), and a ternary system, formic acid-N. N-dimethylformamide-water (HCOOH-DMFH_2O) were measured by using an improved Dvoak-Boublik equilibrium cell. These data were correlated by using Wilson equation and NRTL equation in which the association effect of formic acid was studied by using the bimolecular model. The results were satisfactory.
