  7. Abstract:
  8. In this study, density, viscosity and surface tension of aqueous solution of Sulfolane, ( TEA+TMS+H2O) and (DIPA+TMS+H2O) systems were measured . Density, viscosity and surface tension were measured using pycnometer, Cannon – Fenske viscometer and Capillary rise method, respectively. Surface tension measurements of (DIPA+TMS+water) were carried out by the ring method using a LAUDR TD3 tensiometer,. The experiments were carried out in low concentrations and atmospheric pressure in the temperature range (70 - 30) . The obtained Data was modeled using empirical and thermodynamic models. Density calculation was done using the Setchenov and Redlich – Kister models.and the results indicated that the Relich – Kister predictions are in good agreement with experimental data. Viscosity behavior was investigated on the basis of the activation properties proposed by Eyring and co-workers and equation of Setchenov. Also viscosity data was investigated using the Grunberg - Nissan model. Models used for surface tension are as follows: Setchenov model,chemical and Wang – Fu models, Li – Lu model and macleod – sudgen and Wilson.results show that these models can accurately correlate the surface tension data obtained in this study.Comparison of these models indicates that the Wilson model correlate the surface tension data accurately
