Thanks again Jan. Its 71.8% FFA. But doing acid esterification twice? Do you finish with a base transesterification after the two acid esterification? Please pardon my ignorance. Can you expound a bit. First time to hear about acid esterification twice. Appreciate very much your help on the matter.
Thanks.
