Theory of Simple Mixtures

Abstract

This review is devoted to recent progress in the theory of liquid mixtures of nonelectrolytes. Prior to about 1968 the theory of liquid mixtures was not at all well developed but, largely as a result of progress in the theory of pure liquids, it is now in a much more satisfactory state. Unfortunately, this fact is not very well known. Papers using theories now recognized as unsatisfactory are still common. A recent review of this field has been given by McDonald ( 1) in the Specialist Periodical Reports of the Chemical Society. This same volume also includes short discussions of the application of integral equation methods and perturbation theories to the theory of mixtures by Watts (2) and Smith (3), respectively. The earlier review of Henderson & Leonard (4) is still of value. Gubbins (5) has published a timely review of perturbation theories of mixtures. Mention must also be made of the articles on mixtures appearing regularly in this series. In addition, there is the invaluable Liquids and Liquid Mixtures by Rowlinson (6). Finally, there are some recent articles in this series which briefly mention or relate to the theory of mixtures (7-7c).
