Problem with layering of the mixture?
Thread Content
Calculating phase separation of a two-liquid mixture in PROII: 1. In PROII, lower the temperature of the two-liquid mixture directly from 80 degrees to 30 degrees to observe phase separation; 2. In PROII, lower the temperature of the two-liquid mixture from 80 degrees to 50 degrees to observe phase separation； Then, when the layered material is cooled from 50 degrees to 30 degrees, phase separation no longer occurs! I don’t know why?
Please, the original poster, briefly explain what field of study you’re in; it only shows the conditions at different temperatures, which is confusing :)
The two mixtures are ethyl acetate and water.
“Then, when the layered material is cooled from 50 degrees to 30 degrees, phase separation no longer occurs! ” Did you put the two layered materials back into a single flash? This post was last edited by fj170530 on 2009-2-18 14:32.]
“Then, when the layered material is cooled from 50 degrees to 30 degrees, phase separation no longer occurs! ” Is it that the layered ester is cooled to 30 degrees and then fed into a flash reactor, where no phase separation occurs?
