I make 22 liter batches using a mixture of about 25% methanol and 75% ethanol. All the methanol gets consumed, and some of the ethanol. Since I do a glycerine wash with added water (15% of oil), one batch gives a glycerine layer containing about 2.2 liters of glycerine, 3.3 liters of water, and 4 liters ethanol. I only bother to distill the glycerine layer -- no vacuum, just a fractionating column with reflux. The ethanol comes over with water, of course, about 90% cuz my still is not real efficient. I get about 2.5 liters of the excess ethanol back, which is worth about $3.30 counting my freight costs. My methanol is only $3.00 a gallon, and I probly wouldn't bother recovering it, but it would work even better, since it would come over anhydrous. ------------------------ Yahoo!
