The Study of Vapor-Liquid Equilibrium of Binary System of Tert-Butylamine – Water and Its Thermodynamic Analysis at 84.2 kPa Pressure

To study vapor liquid equilibria of binary system of tert-butylamine – water, anebulliometer was designed in the physical chemistry laboratory of Damghan University.Composition determination was done by using a DR301-95 refractometer the accuracy inrefractive index was 0.0001. Resulted fitting x=f (nD) diagrams were used to determine vaporliquid composition in VLE studies. VLE studies were carried out over tert-butylamine – waterbinary system .Wilson equation was used to correlate data and calculate GE و SE و HE.

In addition, thethermodynamic functions of this system were calculated with the help of the Wilson equation.
