ABSTRACT

Henry s constants of toluene, ethylbenzene (EtB), 1,2,4-trimethylbenzene (TMB), and hexane in di-2-ethylhexyl phthalate (DEHP), diisoheptyl phthalate (DIHP), and diisononyl phthalate (DINP) were determined experimentally applying a dynamic method, at temperatures ranging from (293.15 to 373.15) K and at 1 atm. The logarithms of Henry s constants were fitted as linear functions of the inverse of absolute temperature (thanks to equations similar to the van t Hoff equation). These equilibrium data were predicted with a mean relative deviation of 11 % by the modified UNIFAC thermodynamic model of solution.
