I might not have been too clear here Keith. On occasions when I have been a bit heavy with the caustic I have produced a BD which set to a jelly. Treating this jelly with Glacial acetic acid breaks up the soap into FFA and releases the biodiesel from the jelly. Only problem is as you mentioned we end up with a mixture of BD/FFA/excess acetic acid. Excess acetic acid will wash out. The FFA content can be reduced using slaked lime to enable the BD to be used as automotive fuel. Regards Paul. ------------------------ Yahoo!
