The phenol water system was one of the first of a number of partially miscible liquid systems to be investigated. The mutual solubility has been determined for the pure system at various temperatures and pressures by many investigators.

Particularly interesting is the effect of the addition of a third substance on the mutual solubility of this system.

It is, the purpose of this work to determine the effect of certain previously untried substances on the mutual solubility of phenol and water by investigation of the critical solution temperature before and after their addition. The compounds used have been selected on the basis of their solubility, so as to include compounds soluble in water only, some soluble in phenol only, some readily soluble in both, and some relatively insoluble in both.

The results of the ensuing experiments are to be I interpreted both as individual cases and in the light of the effect of a third substance on partially miscible systems.

The objects of this project are chiefly theoretical as in most of the- work that has been done along the same line. Recently, however, some practical applications have been made. Notable among these is the determination of purity of substances used by comparison of the consolute temperature they exhibit with the known consolute temperature of the pure substances.
