Abstract

Varying proportions of binary mixed solvents of tetrahydrofuran (THF) and propylene carbonate (PC) were prepared and some of their solvent properties investigated. These properties include, excess viscosity, excess volume and Grunberg and Nissan ‘d’ interaction parameter. Investigations were carried out at 25°C. Positive excess volume was observed in the system. Excess viscosities were positive in some fractions and negative in some. The results of the ‘d’ parameter reveals the non-ideality of the mixture formed. Excess Gibb’s free energy (G*^E) of activation is positive in all the fractions investigated.
