Abstract:Densities and viscosities of the binary mixtures of m-cresol with 1,2-dichloroethane, 1,1,1-trichloroethane, 1,1,2,2-tetrachloroethane and tetrachloroethylene were measured at 303.15, 313.15 and 323.15 K. The measured results are used to compute the excess volumes (VE), deviations in viscosity (Δη) and excess Gibbs energy for activation of flow (ΔGE). The excess volumes, deviations in viscosity, and Gibbs energies for activation of flow are fitted to a polynomial-type equation suggested by Scharlin et al. J. Chem. Thermodyn. 34, 927 (2002)] and are discussed in general terms.
Keywords:Excess volume  viscosity deviation  Gibbs energy for activation of flow  m-cresol  chlorohydrocarbons  binary mixtures
