Hello. I think that both the FFA content and water content are too high in that oil. The water content is the worst enemy for a good trans-etherification. Try this : Put the oil in a vessel at 70oC for 24 hrs. The water may form a separate phase at the bottom of the vessel. Check the water content. ExxonMobile sells a nice kit called Mobil water test. The active chemical compound in this is calciumdihydride. It is a reliable method. Do not try to transesterify again until the water content is around 0,5%. And- watch out for any remaining detergents in the oil ! Jan Warnqvist AGERATEC AB
