Excess molar volumes and deviations of refractive indices at 298.15 K for binary and ternary mixtures with pyridine or aniline or quinoline

Excess molar volume (VE) at 298.15 K are reported for the binary systems of heterocyclic nitric compounds: {ethanol + pyridine}, {ethanol + aniline}, {ethanol + quinoline}, {pyridine + aniline}, {pyridine + quinoline}, {aniline + quinoline}, {N-methylformamide (NMF) + pyridine}, {NMF + aniline}, {NMF + quinoline}, {N,N-dimethylformamide (DMF) + pyridine}, {DMF + aniline} and {DMF + quinoline}. The deviations in molar refractivity (ΔR) at 298.15 K are also reported for binary systems: {ethanol + pyridine}, {ethanol + aniline}, {NMF + pyridine}, {NMF + aniline}, {DMF + pyridine}, {DMF + aniline} and {pyridine + aniline}. The determined VE and ΔR were correlated with the Redlich–Kister equation. In addition, the ternary VE data at 298.15 K were predicted with correlated binary parameters for the systems: {ethanol + pyridine + aniline}, {ethanol + pyridine + quinoline}, {ethanol + aniline + quinoline}, {NMF + pyridine + aniline}, {NMF + pyridine + quinoline}, {NMF + aniline + quinoline}, {DMF + pyridine + aniline}, {DMF + pyridine + quinoline} and {DMF + aniline + quinoline}. The ternary ΔR data at 298.15 K are also predicted for the systems: {ethanol + pyridine + aniline}, {NMF+ pyridine + aniline} and {DMF + pyridine + aniline}.
