one phase without any separation.

Ken,
That sounds about right with the base. I haven't given any
consideration of the separation. Are you saying that the glycerol
would stay in the IPesters or the the excess IPA?

I am helping a friend setup a reactor and he has 4 55 gallon drums of

how it goes. Since the it has the higher boiling point we will run at

Are you talking about using isopropanol in a base-catalyzed
transesterification? From what I know about the behavior of
ethanol compared to methanol, I'd be surprised if it worked
at all. I think VERY little isopropoxide would be produced,
and possibly KOH wouldn't even be soluble (this would be easy
to check, of course, I'm just being an armchair commentator
here :-)).
Even if you could get the alkoxide to form, I bet the glycerol
would be too soluble to ever drop out. Have you ever actually
made biodiesel this way in small quantities? -K
