There are a number of factors that in fluence the result of the
trans-esterification. The general rule is that even if you have an extremly
low content of tri-glycerides, you may still have di-glycerides or even, but
seldom mono-glycerides out of spec. And this may be a sign of too low
processing temperature. This subject demands more development than suited here,
I´m afraid.
Best regards

Hey Jan;
Since the reaction proceeds in stages from TRi- to Di- to Mono-glycerides and
then finally to esters, I'm wondering if there is a statistical relationship to
the fractions?? In other words if we do a reaction and find 8% triglycerides
remaining can we estimate the fractions of diglycerides and monoglycerides as
well since they are unmeasureable with this test? Or would the ratios depend
on what type of oil was being used and other factors such as FFA content?

Dear all. I am very flattered that my methanol method had so much
attention. Here is a development of the method:
Equipment needed for the analysis
1.. One 250 ml separatory funnel
2.. One 400 ml beaker (Figure 2)
3.. One magnetic stirrer
4.. Balancer with 0,05g acc.
5.. One 50 ml narrowed neck E-flask
Chemicals for the analysis
1. Water free methanol, min 225 g
2. FAME with water content less than 500 ppm, clear, bright and without
visible impurities, min 25 g
Take the clean beaker and put exactly 225 g of methanol in it. Then add
exactly 25g of the biodiesel. Stir the fluids on the stirrer for 2 minutes.
Take the beaker off the stirrer ans pour the content into the separation
funnel.Take the clean e-flask to the balancer and tarate with the flask. Let
any oil phase separate out from the biodiesel/methanol phase and put it in the
e-flask. Weigh the content and calculate the result:
1 - m1/m2 = m3
where m1 is the mass of the biodiesel
m2 is the amount of methanol
m3 is how much of the biodiesel put in that is consisting from methyl
esters.
The method will show huch much of the material by mass that is soluble in
methanol. This includes mostl mono- and diglycerides. The residue consists
therefore mostly from unreacted oil.
With best
Jan Warnqvist

Look for a mitsubishi delica. A buddy of mine just imported one with
low miles from Japan. He loves it.

Hello All,
I am a Kid's Birthday Party Entertainer, as well as a Juggler,
Magician, and "Balloon Guy."
I live in the Midwest, and have all 4 seasons during the year, if
this is a helpful bit of information.
Lately my entertainment business has gotten really busy and it's
come time for me to buy a larger vehicle. I have been a fan of alternative
fuels for years, but never pursued a diesel vehicle.
I would like recommendations on what type of deisel van would you
recommend that would most easily transfer over to a SVO, WVO, or biodiesel
system for me to drive? I am looking for a 1/2 or 3/4 ton van, not really a
"minivan" type of vehicle.
Again, I am naive and new to all this and hope your thoughts will
help ground me and get me pointed in the right direction. I guess I have to go
buy a diesel vehicle before I can get moving on SVO, WVO, or Biodiesel fueling,
right?
Thank you very much.
Luke
