WebMar 12, 2024 · The CST obtained from pure phenol-water system was 67.5⁰C. What is the critical temp of water? 2.4. The point at which the critical temperature and critical pressure is met is called the critical point. The critical pressure and critical temperature of water and steam are 22.12 MPa and 647.14 K, respectively. WebPhenol-water systems If the third substance dissolves in both liquids (and the solubility in each of the liquids is of the same order), the mutual solubility of the liquids will be increased and an upper C.S.T. will be lowered, as is the case when succinic acid or sodium oleate is added to the phenol - water system.
