EXCESS VOLUMES AND VISCOSITIES OF BINARY-MIXTURES OF TRICHLOROETHYLENE WITH BRANCHED ALCOHOLS

Excess volumes (V-E) and viscosities (eta) of binary liquid mixtures o f trichloroethylene with branched alcohols have been measured as a fun ction of composition at 303.15 K. The branched alcohols include 2-prop anol, 2-methyl-1-propanol, 3-methyl-1-butanol, 2-butanol and 2-methyl- 2-propanol. Further, the deviation in viscosities (Delta ln eta) have been computed from viscosity data. The V-E values are positive in mixt ures of trichloroethylene with 2-propanol, 2-butanol, 2-methyl-2-propa nol and an inversion of sign from negative to positive is observed in the mixtures of trichloroethylene with 2-methyl-1-propanol and 3-methy l-1-butanol. The values of Delta ln eta are negative in all the mixtur es except at lower mole fraction of trichloroethylene in the system tr ichloroethylene with 3-methyl-1-butanol.
