Topologic Transformation of Inorganic Salt–Oxyethylated Surfactant–Water Phase Diagrams in Response to Changing Temperature

Аннотация

A general topologic transformation scheme of phase diagram is proposed for inorganic salt–oxyethylated surfactant–water systems that have a lower critical solution temperature (LCST) or where the surfactant–water binary subsystem is homogeneous over the entire range of liquid temperatures for the case where the salt has the salting-out, salting-in, or salting-in-and-salting-out effect. Examples are provided to illustrate the implementation of the suggested variants of the general scheme.
