Abstract

The Meissner-Greenfield correlations of azeotrope composition and boiling point have been checked with new data with satisfactory results except in the cases of hydrocarbons—acids and halogen hydrocarbons—acids.

A modification of these correlations for azeotrope composition has been extended to other combinations of organic liquids where the deviations from Raoult's law can be predicted from the hydrogen bonding characteristics of the components.

A simple empirical linear equation for azeotrope boiling point has been applied to most of the cases included in the above correlation.
