Excess molar volumes and viscosities of mixtures of some n-alkoxyethanols with dialkyl carbonates at 298.15 K

Excess molar volumes VmE and viscosities η have been measured as a function of composition at atmospheric pressure and 298.15 K for nine {an alkoxyethanol+dimethyl carbonate (C3H6O3), diethyl carbonate (C5H10O3), or propylene carbonate (C4H6O3)} mixtures. The alkoxyethanols were 2-methoxyethanol (CH3OCH2CH2OH), 2-(2-methoxyethoxy)ethanol {CH3(OCH2CH2)2OH}, and 2-{2-(2-methoxyethoxy)ethoxy}ethanol {CH3(OCH2CH2)3OH}. The VmE for each of the carbonate mixtures studied decrease in magnitude as the polar head group of the alkoxyethanol increases. From the experimental results, deviation in the viscosity (Δlnη) have been calculated. The experimental results have been correlated using the Redlich–Kister equation to estimate the coefficients and standard errors. The experimental and calculated quantities are used to discuss the mixing behaviour of the components.
