Studies on associated solutions. Part II. Physicochemical properties of acetonitrile-propan-2-ol mixtures

The H-1-NMR spectra of liquid binary mixtures of acetonitrile and propan-2- ol, were recorded at 298 K over almost the whole range of the mixed solvent compositions. From these data were found the values of the spectral parame ter, Delta delta>(*) over bar * (ACN-PrOH-2). The densities (d(12)) and rel ative permittivities (epsilon (12)) Of the mixed solvent were measured at 2 88.15 K, 293.15 K, 298.15 K, 303.15 K and 308.15 K, as well as refractive i ndices at 298.15 K. From all these data, the molar volumes (V-m), temperatu re coefficients of relative permittivities (alpha (12)) and their deviation s from ideality were calculated. Additionally, the Kirkwood's correlation f actors (g(K)) were found. The values of these properties are discussed in t erms of interactions of acetonitrile with propan-2-ol.
