Abstract
The partial molar volumes of a variety of aliphatic amines and amides in water at 25°C have been determined, and related to their van der Waals volumes. In accordance with earlier studies the relationship between partial molar and van der Waals volumes is shown to depend upon molecular geometry. Hydrogen bonding to the solvent causes a volume reduction and group contributions (decrements) for such interactions of amines have been obtained. Additivity of group contributions is shown to allow the prediction of partial molar volumes for nitrogen-containing compounds.Keywords
