No, but what's the dark layer on top? Do you mean you think the biodiesel layer is darker than it should be? >I use Phenolphthalein and am concerned that it is not working correctly.

You're correcting a phenolphthaleihn solution reading with pH test strips? That doesn't sound wise. If your phenolphthalein is fresh it should be fine. Store it in a dark place. >I think this is causing me to >have incomplete reactions. > >Should the BD be hazy after the reaction takes place? Usually. Are you using SVO or WVO? I don't know what method you're using and you don't describe what you did. Do it this way: Make your first test batch http://journeytoforever.org/biodiesel_make.html#biodnew Check your test batches with the wash-test: http://journeytoforever.org/biodiesel_vehicle.html#quality Best wishes Keith _______________________________________________ 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/
