Abstract

The mutual solubility of two liquids which are not miscible in all proportions is essentially a function of the temp. Rising temp usually increases the solubility, possibly reaching a point, i.e., the upper critical solution temp (CST), at which the two components become miscible in all proportions. The CST is characteristic for the two liquids involved.

A microtechnique developed by Fischer simplifies rapid and accurate determinations of the upper critical solution temp. This technique is described and its application to the characterization and identification of pure lipids and lipid mixtures is demonstrated. The significance of this simple laboratory procedure and its relation to complementary analytical methods is discussed.
