>>I finally took the step of making a test batch of biodiesel. At least I >>have attempted to mix teh methoxide. I bought a bottle of HEET gas line >>antifreeze which is reportedly of a high enough purity to use, and a jar >>of red devil lye. I mixed about 7 grams of lye to a bit better than 300Ml >>of Methanol. How long before I have useable methoxide? IO tried looking >>at Keith's site, but apparently its down tonight or else my browser is >>having trouble recognizing it. Can you all help me?

And I'll be more precise with my measurements. i think I used too much lye and that caused too much saponification. I'll let you all know how batch No 2 comes off tonight. J.D. >
