Hi All
One man's terrorist is another man's freedom fighter.
We in South Africa have been there, seen it, lived it and maybe got past
some of it.
What would this piece of legislation have done to the ANC's London office.
Would there have been anywhere near the pressure that was brought to
bear

Hello John
JTF states in Section 5
(http://journeytoforever.org/biodiesel_make.html#biodnew) , to
carefully decant the BD off the top, making certain not to get any
of the glycerine in the BD. If you do, resettle and and try again.
Not quite right. Why not just quote it, copy and paste?
Dear sirs:
1.-Could you please indicate me if Free Fatty Acids are soluble in:
a) Glycerine
b) Biodiesel (tallow ethyl ester).
2.- Using Ethanol 99.9%, KOH, beef talow, I obtained BD (liquid at 25ºC,
77ºF) but glicerine separation not detectable.
Any suggestion?.
Thanks in advance,
Mr.

Nearly insoluble in glycerol, fully soluble in biodiesel.

Hello André

Indeed.

Some of it, maybe. I left when there was no further hope of a
peaceful outcome (1977), but there's hope now, and good reason

The following is my modification of that procedure
which works for us, and takes less time, but requires
more catalyst.
Dissolve 1 ml sulfuric acid in 150 ml methanol and
add to 1 liter liter

Bob,
Why not drain the small amount of glycerol that settles out of an
esterification? The majority of the sulfuric will come out with it. That
lessens the amount of base catalyst needed for the follow-up
transesterification.
Fewer chemicals in, fewer problems out.

Ken,
Acid catalysis works well. Industry often uses feedstock of 100% FFAs in
order to achieve a pure or nearly pure mono-ester product.
The easiest way to test the theory on a pauper's budget is to take the
glyc cocktail from two side-by-side trials from identical feedstock and
reaction

Bob,
Additionally, if I do wait and do get some
glycerin to settle out with my conditions,
wouldn't you think that methanol also would
be part of the cocktail, thence affecting
the equilibrium?
Roger that. Hence the counter measure of adding back as much alcohol to
the base side as the

Prakash Chhagani,
Can you please send details of what you can supply in the
range of Jatropha of the non-toxic variety. Would like cost of DHL from you to
me here of 5,000 seed lots.
Thank you for your help.
