Excess molar volumes and Viscosities for binary mixtures of 2-propoxyethanol and of 2-isopropoxyethanol with 2-pyrrolidinone, N-methyl-2-pyrrolidinone, N,N-dimethylformamide, and N,N-dimethylacetamide at 298.15 K

Excess molar volumes V-m(E) and viscosities eta have been measured as a function of composition for binary mixtures of 2-propoxyethanol and of 2-isopropoxyethanol with 2-pyrrolidinone, N-methyl-2-pyrrolidinone, N,N-dimethylformamide, and N,N-dimethylacetamide at 298.15 K. In all mixtures, the excess molar volumes are negative over the whole mole fraction range. From the experimental data, deviations in the viscosity Delta In eta had been calculated. The excess volumes and viscosity deviations have been correlated using the Redlich-Kister polynomial equation by the method of least-squares for the estimation of the adjustable parameters and the standard errors. The viscosity data have been correlated with the equations of McAllister, Heric, and Auslaender.
