Azeotrope of toluene-water
Azeotrope of toluene-water
(OP)
Hi everyone,
Does anyone know, or have access to, charts for the azeotrope of toluene and water. We are doing a decanting and the results are not promising. As I suspected, we are seeing cloudiness. As I understand the process, our operating temperature is about ambient thanks to the addition of DI water. The organic phase enters the process at probably 40 C. Of course, it's not winter anymore so nobody's thinking about how badly this solution of C10+ alkenes, toluene, and water is going to behave once the ambient temperature drops below 10 F. The aqueous phase is already cloudy at ambient.
The pH may not be completely neutral, though it is supposed to be. The density is about 0.8-0.84 for the heavy organics and obviously about 1 for the water.
Any thoughts?
