Normal distillation should separate them. MeOH bPt. 65°C, ethyl benzene BPt. 136°C
So you should be OK.
I don't think they form an azeotrope.
Thanks!
Although, Benzene forms an azeotrope with MeOH (BP = 58 C)
Also, Toluene forms an azeotrope with MeOH (BP = 63 C)
p-xylene also forms a 64 C azeotrope.
I just found this out. Is EB sufficiently similar with any of Benzene, Toluene or p-Xylene to potentially suspect a similar azeotrope in EB? I'm not really sure how similar I ought to think these molecules are and further if such similarity extrapolates well to VLE.
Maybe I should just end up trying it out..
Any other ways of predicting azeotropes? Group contribution, activity constants etc.?
