DENSITIES AND VISCOSITIES OF 1,1,1-TRICHLOROETHANE WITH 13 DIFFERENT SOLVENTS AT 298.15 K

The aim of this investigation is to study the behavior of 1,1,1-trichl oroethane as a component of binary mixtures. Density and kinematic vis cosity were measured at 298.15 K and atmospheric pressure with a vibra ting tube densimeter and an Ubbelohde capillary viscometer, respective ly, for binary mixtures of 1,1,1-trichloroethane with 13 solvents of d ifferent chemical nature: methyl and ethyl acetate, acetone, butanone, cyclohexanone, 2-methyltetrahydrofuran, dipropyl ether, 1,4-dioxane, nitromethane, 1-hexanol, 1-methoxy-2-propanol, alpha,alpha,alpha-trich lorotoluene and alpha,alpha,alpha-trifluorotoluene. The dynamic viscos ity, excess volume, and viscosity deviation function were obtained fro m the experimental results. A polynomial expression was employed to co rrelate excess volume data, and the Cao et al. model (UNIMOD) was used to correlate mixture viscosity. Parameters for these models are repor ted.
