Thank you Joe.
The determination by mass will give you a more precise idea of the methyl ester
content.

Hey Jan;
Let me take the chance to thank you again for your contributions. Also I'd
like to let you know how WE have evolved your idea. Me and this other dude in
town ( who might be lurking here....lol - it was his idea actually) have taken
to doing some kind of variation on your idea which helps us in the middle of
the process. I know you are talking about testing clean, washed and dried
fuel, but check this out; We take a sample ( I have a small test tube so I use
3 ml of fuel and 27 ml meoh) after the reaction but before washing. I know
this contains catalyst, soap, water and whatever BUT when I stir it up, any
unreacted oil settles out very quickly and gives me a gauge of how close I came
to a complete reaction. I can even measure the percentage of unreacted oil and
use this to determine how much catalyst and methanol to hit the reactor with in
order to complete the reaction. The unreacted stuff is treated as neutral oil
when determining catalyst and methanol amounts ( ie 12% meoh v/v and 4.9 g/l
koh) If I am good and the reaction was very complete the first time, then only
a little white powder (soap/catalyst?) settles in the bottom and the rest is
clear and bright. This is more useful than a pop bottle wash test IMHO.
best regards
Joe

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.

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
