ABSTRACT
Activity coefficients at infinite dilution values are of great importance when designing separation processes like distillation, liquid liquid extraction and gas stripping. In this study the dilution values were determined for four compounds in water that are present in bio-oil. Henry s law constants (H), Partial molar excess enthalpies at infinite dilution HE;1 i and air water partition coefficients (Kaw) are also reported. The measurements were performed using inert gas stripping equipment (dilutor) in the 298 340 K temperature range. Mass transfer study was also performed to investigate the equilibrium between the solution and the gas leaving the cell.
