Excess volumes and viscosities of binary mixtures of trichloroethylene with branched alcohols

Excess volumes (VE) and viscosities (η) of binary liquid mixtures of trichloroethylene with branched alcohols have been measured as a function of composition at 303.15 K. The branched alcohols include 2-propanol, 2-methyl-1-propanol, 3-methyl-1-butanol, 2-butanol and 2-methyl-2-propanol. Further, the deviation in viscosities (Δlnη) have been computed from viscosity data. The VE values are positive in mixtures of trichloroethylene with 2-propanol, 2-butanol, 2-methyl-2-propanol and an inversion of sign from negative to positive is observed in the mixtures of trichloroethylene with 2-methyl-1-propanol and 3-methyl-1-butanol. The values of Δlnη are negative in all the mixtures except at lower mole fraction of trichloroethylene in the system trichloroethylene with 3-methyl-1-butanol.
