Viscosities of mixtures of chloroform + triethylamine: analysis in terms of three components (A, B, and AB)
Viscosities and densities of highly non-ideal mixtures of chloroform (A) + triethylamine (B) have been measured at 25 °C. It has been shown that the Grunberg equation (one adjustable parameter) can account for these viscosities over the whole range of compositions. It has also been shown that a new combination of the ideal associated solution model, based on consideration of an equilibrium of the type A + B = AB, with an ideal viscosity equation (also one adjustable parameter) accounts more accurately for all of the viscosities. This latter treatment also has the advantage of offering a clear pictorial model of the mixtures. Keywords: viscosity of solution, complex formation in solution, chloroform + triethylamine, triethylamine + chloroform.
