fatty acids in a sample of dirty oil. One way to refine WVO would
be to esterify the
Livio asks:
Do you know the difference of using ethanol or methanol in the
process of producing biodiesel?? because over here in Italy I can't

It's somewhat more difficult to use ethanol, but it can be done.
The alcohol must be anhydrous, and the oil must be totally dry

Ok, that is basicly were I was going with this, useing a small amount
of methanol to make useing the ethanol easier to use.
Yup, it works. For oil above a titer of 2.5 ml or so (of 0.1% NaOH), I
do a caustic refining step. For oil between 1.0 and 2.5, I use a mix of
3 parts ethanol to 1 part

I reread my recipe in your reply, and I see a glaring error:
For the ethoxide, dissolve 7g NaOH or 10g KOH in every liter
of alcohol

10g KOH in the ethanol. That'll work better :-).
