When I first got started I dedicated a kitchen blender, a re-sealable
Grolsch beer bottle (for the methoxide) and a small saucepan to the project
along with a simple thermometer that I used to use for checking refer loads
while trucking (about $9). I only made 500ml test batches rathere than full
1 liter ones and just did the math to calculate the ingredients.After
titrating to determine the amount of NaOH or KOH to mix into the methanol;
Fill saucepan with oil, heat to 130F (55C) while mixing up the methanol and
lye. Be sure all the lye has disolved in the methanol. (the Grolsch bottle
was great for this) and that the oil is no more than the 55C or the
methoxide will want to boil off it's methanol (148.5F) and that is no good
for a complete reaction.
Oil is at 55C and methoxide is ready. Pour hot oil into blender,flip on
blender (which will no longer be used for food) and slowly add the methoxide
through the top opening of the blendeer. Close top and allow to blend for
about 18-20 minutes.
Toss the lot into a Masson jar and let settle. In the morning you should
have a clear seperation of BD on top and glycerine on the bottom, providing
everything was mixed properly.
And the rest, such as washing ect is pretty well explained at the link.

Subject: [Biofuel] first batch of biodiesel
Hello biofuels people,
I am about to start making my first batch of biodiesel and I have a whole
bunch of questions.
in much of the literature it says that it is important that your reacting
vessel be sealed to keep the fumes in but the logistics of how to do that
while simultaneously stirring and measuring temperature aren't very well
covered until you get into building a complicated reactor (probably not
worth it for my 1L test batch) I want to make a jarful, does anyone have
any good suggestions for fume management. I saw some mention of using a
blender but it is not immediately apparent how one would maintain
temperature while blending.
I saw people throw out their price per gallon as being in the 40-75 cent
range, what are people paying for methanol to be getting those prices?
what portion of the methanol is reclaimed? I got my methanol from mcmaster
carr for $43/5 gal, they haven't told me yet what it is going to cost to
ship even though they promise to ship it today, I am expecting that it
will be expensive because it is flammable and toxic.
I was looking for an electric immersion heater but I couldn't find one for
less than 5 gallons (too big to fit in a jar) should I do some sort of a
double boiler on a hot plate???
what kind of a return should I expect, if I start with 1L of oil and 250mL
of methanol and 6.25g of lye (planning on doing the 2-stage recipe) how
much of each of the products should I expect?
Thanks in advance for all of your help!! this is a great list!
