It is difficult. If you can dissolve the required amount (perhaps by boiling the ethanol/NaOH mixture under reflux), you could possibly make biodiesel out of very clean dry oil. If you only use 3.5g NaOH per liter of oil, or if your ethanol or oil contain any water, you will probably never achieve separation of a glycerine phase. All your ingredients go into a clear solution, and just stay that way forever. Until glycerine separates, you don't have biodiesel. -K _______________________________________________ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
