could you please indicate Amberlite type you used?.
Did you removed water in as much it was formed?.
Could you describe the "reactor" you used, specially how you placed the
catalyst?.
Many thanks in advance,
Francisco

Iwan,
Please take a moment to quantify/describe and identify the location of
what you perceive to be "a lot of soap."

Subject: [Biofuel] Pre transesterification with heterogen catalyst
Dear,
I have an laboratorium experiment about biodiesel from crude palm oil
(CPO). my CPO have high FFA (acid value 46)
first, I try to remove the FFA with esterification. I used cation
exchanger (Amberlite) as catalyst. its succes to reduce the acid value
from 46 to 1.3.
then, transesterified using KOH as catalyst. after this reaction, I wash
the ester using warm water. but, I found a lot of soap when I mix the
ester with water. I can't explain why, may somebody help me?
Regards,
Iwan Prawito
