## Abstract A corresponding states approach has been used successfully to correlate reduced selfβdiffusivity of pure liquids with reduced temperature and acentric factor. In addition, dimensional analysis techniques have been used to accurately relate viscosity, normal boiling point and temperature
A new semiempirical model for prediction of self-difision phenomena in liquids is proposed. Assuming analogy between the concept of a free volume in liquids and a porosity of a granular medium, a capillary model of the granular bed and the Kozeny-Carman theory was applied to determine self-difision
