Apparent molar volumes (<img src='http://www.niscair.res.in/jinfo/V phi-B.gif' border=0>) of dilute solutions of triethylamine in heptane, 2-butanone, ethyl ethanoate, butyl ethanoate, 1,4-dimethylbenzene, ethylbenzene, chlorobenzene, and nitrobenzene, at 303.15 K have been calculated from the densities determined. The limiting partial molar volumes (<img src='http://www.niscair.res.in/jinfo/V B-infinity.gif' border=0>), limiting excess partial molar volumes (<img src='http://www.niscair.res.in/jinfo/V B-E-infinity.gif' border=0>) and volumes of transference (<img src='http://www.niscair.res.in/jinfo/del V-B-tr-infinity.gif' border=0>) from heptane to the other investigated solvents of varying polarity have been analysed in terms of solute-solute-solvent interactions and structural effects of the molecules. Using the Terasawa model, an attempt has been made to find a measure of the contribution of specific interactions in terms of void volumes of triethylamine in the investigated solvents over a range of polarity. The Flory theory/ERAS model has also been applied to estimate the apparent molar volumes, excess apparent molar volumes and limiting excess partial molar volumes of triethylamine in investigated systems. |
