Partial molar volumes of linear hydrocarbons in methanol in the very dilute region. Intermolecular interactions. H-bond effects

Limiting partial molar volumes V-B(infinity) for the linear hydrocarbons, C-5, C-6, C-7, C-8 and C-10 in methanol were determined with a vibrating tube densimeter at 24.994 degreesC (ITS-90). V-B(infinity) and b(V) were discussed in terms of solute-solvent and solute-solute molecular interactions, focusing on H-bond cleavage, hydrocarbon short-range correlations of molecular orbitals and conformational effects. V-B(infinity) (HS)/V-B (HS) values calculated according to Lee's hard-sphere mixtures model are compared with experimental values. A discussion is presented and deviations are interpreted in terms of size, shape, packing densities and H-bond effects.
