A simple solubility theory combining solubility parameter and Lewis acid-base concepts

A simple model of liquid / liquid solubility has been developed. The existing solubility parameter theory which tries to explain solvent - salute interaction in terms of dispersion , polar , and hydrogen bonding interactions is discussed. The current theory has been widely used qualitatively but can not be used quantitatively due largely to incorrect modeling of the hydrogen bonding interactions. This research proposes modifications to the current solubility parameter theory that are designed to overcome the problems encountered with hydrogen bonding interactions in which the hydrogen bonding interactions are described as a special case of more general Lewis acid - base or donor acceptor interactions. The specific electron - pair acceptor - donor properties themselves are quantitatively characterized using acceptor numbers (AN) and donor numbers (DN)
