Cst phenol water system
WebFor small molecules, the existence of an LCST is much less common than the existence of an upper critical solution temperature (UCST), but some cases do exist. For example, the system triethylamine -water has an LCST of 19 °C, so that these two substances are miscible in all proportions below 19 °C but not at higher temperatures. WebMay 26, 2013 · When phenol and water are immiscible with each other, the degree of freedom, F = 2 − 2 + 2 = 2. Since this is a condensed system which means the pressure …
