Hi to all,
There was similar question about Sunflower Oil about month ago, and answer
from Ken Provost [EMAIL PROTECTED] was:
"> Sunflower oil has an IV of 133. This is even higher than soybean oil.
> Polymerization concerns arise.I am now looking for a sorce of good
> peanut wvo. peanut oil has an IV of 92 (sweet).

*I don't think IV matters much for biodiesel, maybe unless you're
*leaving it around for years before burning it. Check out
www.biodiesel.org/resources/reportsdatabase/reports/gen/20020101_gen-345.pdf
*Structure Indices in FA Chemistry. How Relevant is the Iodine Value?,
*Gerhard Knothe, 2002, Journal of American Oil Chemists' Society.
*Basically, IV only matters if you're burning straight oil. Once you
*turn it into biodiesel, it doesn't matter. Even linseed makes OK
*biodiesel. There's lots of references in the paper to other research
*which arrives at similar conclusions.

So if I understand it correctly, it seams that after transforming SVO/WVO to
BD polymerzation problem does not exisit any more,
Am I right, or that also means that Sunflower Oil is also bad choice for BD
making?
Regards,
Denis

Hello DB.
Quoting :"Trans esterifying triglyceride oils and fats with
monohydric alcohols to form biodiesel largely eliminates the tendency of the
oils and fats to polymerization and auto-oxidation.." I can add that this is
the exact scenario with methyl ester from fish oil and linseed oil.
