Abstract
The densities, viscosities, sound speeds, and relative permittivities for four binary mixtures of glycols+organic solvents that are miscible over the complete composition range, namely, diethylene glycol (DEG)+nitrobenzene and triethylene glycol (TEG)+chlorobenzene, +bromobenzene, and +nitrobenzene have been measured at atmospheric pressure and at temperatures from 298.15 to 313.15 K. The excess molar volumes are calculated and fitted with a Redlich–Kister type equation. The qualitative analysis of excess molar volumes revealed that the structure-making effects probably in the form of weak Cl· · ·H–O hydrogen bonding, Cl· · ·O electron acceptor–donor interactions, and interstitial accommodation of chlorobenzene in associate structures of triethylene glycol, etc. are predominant in these mixtures.
