Abstract

The densities $\rho $ ρ of binary mixtures of 2-(dimethylamino)ethanol and 2-diethylaminoethanol with pyridine were measured over the entire concentration range at 293.15, 303.15 and 313.15 K. The values of excess molar volume, $V_m^E$ V m E , apparent molar volume, ${V_{\varphi ,DMAE}}$ V φ , DMAE and ${V_{\varphi ,DEAE}}$ V φ , DEAE ; partial molar volumes, ${\bar V_{m,1}}$ V ˉ m , 1 and ${\bar V_{m,2}}$ V ˉ m , 2 , excess partial molar volumes, $\bar V_{m,1}^E$ V ˉ m , 1 E and $\bar V_{m,2}^E$ V ˉ m , 2 E have been computed using the experimental observations. The partial molar volumes, $\bar V_{m,1}^o$ V ˉ m , 1 o and $\bar V_{m,2}^o$ V ˉ m , 2 o ; excess partial molar volumes, $\bar V_{m,1}^{oE}$ V ˉ m , 1 oE and $\bar V_{m,2}^{oE}$ V ˉ m , 2 oE at infinite dilution were also calculated. The variations of these parameters as a function of composition and temperature are discussed in terms of the intermolecular interactions in the studied binary mixtures. [ABSTRACT FROM AUTHOR]
