 1.-Could you please indicate me if Free Fatty Acids are soluble in:
 a) Glycerine
 b) Biodiesel (tallow ethyl ester).



Nearly insoluble in glycerol, fully soluble in biodiesel.



 2.- Using Ethanol 99.9%, KOH, beef talow, I obtained BD
 (liquid at 25ºC, 77ºF) but glycerine separation not detectable.
 Any suggestion?.


Read The JtF webpages about ethyl esters. If you don't
get glycerine separation, it's not really biodiesel.
