✦ Synopsis


Krafft points of diacylglycerophosphocholines (PC) were measured in alkanes-cyclohexane solutions by differential scanning calorimetry, and it was found that they were regularly increased following the increase in alkane content in the solutions and the chain length of the alkanes. From these results it was deduced that the mixing of PC with alkanes occurred in the gel state of the PC, but not in micelles at higher temperatures above the Krafft points, where miceUar solutions are provided. The penetration of alkanes into gel state PC was found to be dominated by Langmuir type interaction, and the affinity of alkanes increases with increasing in chain lengths. Above the Krafft points, the micelle formation was'conficmed by using the fluorescence probe technique.

An equilibrium is homogeneous when all components are either exclusively in the gas phase or exclusively in solution. For gas-phase equilibria, the ratio of the product concentrations for end and starting materials is constant at a given temperature (law of mass action of Guldberg and Waage, 1867).
