Hello Keith and all.
The trans-esterification does not produce any water, but some water present
(0,1%) is necessary to make the process run well. The acid esterification
produces water with 1M /M alkylated fatty acid. This process will also
perform trans-esterification assuming that there is some material to
trans-esterify and that the operator in question lets the process continue.
With best regards

Hello all
A question...
Even when everything is dry, including the oil, the
transesterification process itself produces some water, though not
very much.
IIRC acid esterification also produces water, I think more water than
transesterification does, and via a different process.
Does anybody know if that's correct, and what the chemical equations
are? With KOH and H2SO4.
Thanks!
All best
Keith
