David, Keith, Haven't tried mixing BD and ethanol but found BD and methanol did not mix. Recent batch from high FFA WAF turned to soap. Broke the emulsion with conc acetic acid, filtered and washed the BD +FFA. Mixture titrated equivalent to 3.25g NaOH/L (titration method as per feedstock). Decided to esterify the FFA content using ethanol. Surprisingly the absolute alcohol mixed completely (single phase, clear liquid) with the BD/FFA mix.
