Abstract
Viscosities and refractive indexes were experimentally measured for binary mixtures of terpinolene with o-, m- and p-cresol for entire composition range at 303.15, 308.15 and 313.15 K and at atmospheric pressure. Deviation in viscosity , excess Gibbs energy of activation for viscous flow , enthalpy and entropy of viscous flow, deviation in refractive index , molar refraction and deviation in molar refraction were also calculated. Various theoretical viscosity relations such as Dolezalek-Schulze ( , Grunberg-Nissan , Tamura-Kurata Katti-Chaudhri ( , McAllister relation ( and ), Kendall-Munroe relation, Bingham relation and Arrhenius-Eyring relation were calculated. Similarly, nine theoretical refractive index relations such as Arago-Biot (A-B), Dale-Glastone (D-G), Lorentz-Lorentz (L-L), Eykman (Eyk), Weiner (WR), Heller (Hr), Newton (Nw), Oster (Os) and Eyring-John (E-J) were also calculated with their standard deviation values. Results were discussed in terms of the presence of intermolecular interactions between the components of binary mixtures.
