Abstract
Apparent molar volumes VÏ,B of n-propylamine, n-butylamine, di-n-propylamine, di-n-butylamine, tri-n-propylamine, and tri-n-butylamine in tetrachloromethane and trichloromethane at 303.15 and 313.15 K have been calculated from the densities Ï determined with high precision vibrating tube densimeter. From these data limiting partial molar volumes V¯Bâ and limiting excess partial molar volumes V¯BE,â were estimated. The results are analysed and interpreted in terms of solute-solvent interactions and structural effects of the molecules. An attempt to find a measure of the contribution of the specific interactions to the partial molar volumes of primary, secondary and tertiary amines in tetra- and tri-chloromethane was made using Terasawa model, scaled particle theory (SPT) and hard sphere theory (HST).
