Abstract

 A solvent that creates less hazards to human, animals and environment is called a green solvent. The
separation of Benzene/Acetonitrile mixture is carried out using Dimethyl sulphoxide as an entrainer. Dimethyl sulfoxide
can be replaced by a greener solvent, 2,2,4-trimethylpentane, also known as iso-Octane. The vapour-liquid phase
equilibrium data that are required for the design of separation system for the iso-Octane / Benzene mixture are not
available in the literature. The experimental measurement of phase equilibrium data for vapour and liquid is a timeconsuming and a costly affair. Instead, group contribution method such as modified UNIFAC Dortmund method can be
used to predict the vapour-liquid equilibrium data. These data can be used for the design purpose. However, these data
can be used for only preliminary design and for the final design of separation system, experimental data are
indispensable.
