Hi Ken,
Calcium oxide also reacts with ffa and glycerides to make calcium soaps.
These soaps are the basis of most greases used to lubricate moving
machinery. Whereas sodium salts have the ability to disperse small amounts
of oil into water, calcium (magnesium, zinc etc.) soaps have the abilit
Hi Michael et al
Im wondering if anyone has looked at calcium oxide as
a reactant/catalysis. CaO is very hydroscopic and
should(?) suck up all the H2O and ffas. Im thinking
about this in order to use hydrated rice straw derived
ethanol directly from fermentation rather than going
through lab
Dear Colton (and indirectly Girl Mark),
I think pH meters are very stable and reliable instruments these days. But
you have to rememebr that they measure the hydrogen ion concentration in a
solvent that allows ionisation such as water. (Indeed, the pH scale is
devised so that pH 7 is as neutra
We are using a pH meter (& visual) methods during our titration to determine
the ffa%. It is very frustrating since the pH meter readings are very
inconsistant. Our current ffa% is 1.6% and we are trying to reduce it to .5%
by acidification.
Any comments on methods for determing the ffa%?

How were you able to know that your ffa's increase?
If you are just using a pH meter, it is but natural that the pH will fall
since you are using a strong acid H2SO4.
If you are titrating with NaOH, H2SO4 will eat up a considerable amount of
lye.
