Hello Lee Did you have any results yet with heads and tails tests?
Best Keith >Keith: Thanks for responding. I do a second distillation using calcium >chloride and then 3A molecular sieve to dry the alcohol. So far I have been >using 50% lard mixed with 50% soybean oil (both used) . I am in the process >of eliminating the lard and using used soybean oil with a titration of 2 >grams NaOH per liter. I use KOH at the U. of Idaho's recommended amount of 1.3 >Kg per 100 liters of oil. I have been using 1/3 purchased methanol mixed with > 2/3 self produced ethanol and using 20% alcohol by volume in the reaction. > The ethanol is 99% pure.
