| Abstract: | 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. |
