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 K 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.
