Phenol in water critical solution temperature

WebThe classical example water-phenol was chosen for study, and the densities of solutions of “phenol in water” and of “water in phenol” have been determined every 10° from 20° to 70°. The densities of the conjugate solutions have also been measured at more frequent intervals near the critical solution temperature. Footnotes. Webmiscible liquid pairs - E.g. Phenol-Water, Aniline-cyclohexane and Methanol-carbon disulphide[1]. Partially miscible liquids become more soluble with the increase in temperature and at a certain temperature they are completely miscible[2]. This temperature is known as the critical solution temperature (CST).
