You need to read this below - there are two long web pages of it, it's worth your reading it all. For instance, you'll see headings there such as "How the process works" and "What are Free Fatty Acids?" but reading it all will help you to understand them clearly. http://journeytoforever.org/biodiesel_make.html Make your own biodiesel: Journey to Forever Three choices 1. Mixing it 2. Straight vegetable oil 3. Biodiesel Biodiesel Where do I start? What's next?

Ethyl esters -- making ethanol biodiesel Reclaiming excess methanol More about lye How much lye to use? Basic titration Better titration Accurate measurements pH meters Phenolphthalein High FFA levels Deacidifying WVO No titration? The basic lye quantity -- 3.5 grams? Mixing the methoxide Test batches Stock methoxide solution How much glycerine? Why isn't it solid? PET bottle mixers Viscosity testing How the process works What are Free Fatty Acids? Which method to use? Why can't I start with the Foolproof method? Quality Quality testing Other uses Identifying plastics Separating glycerine/FFAs Best wishes Keith ------------------------ Yahoo!
