JG, Guru? No. Serious about it? Yes.
The volume of glycerin cocktail that settled out should give you an idea of where the problem might lay. Presuming you used a ratio of 5:1 oil/alcohol, you should have had approximately 5 gallons of glycerin cocktail. It sounds as if your reaction didn't go to completion. Your description of "milk" also sounds like an indicater that your reaction didn't go to completion, leaving you with mono- and di-glyceride emulsifiers. The pertinent question is how thick of an emulsion layer did you get? Upon washing, there should be nothing more than perhaps a 1/8" emulsified layer between the water and fuel phases. Presuming that your wash/fuel separates at all, pull off a liter from the top and retreat it as if it were the first time you had seen it. Make sure to dry it first. See if anymore glycerin drops. It's a safe bet that some will. If so, you'll need to separate what you can on your larger batch. Time is one method, albeit excruciatingly slow. You could use regular table salt mixed with water to salt out a bit more. A small amount of phosphoric or sulfuric acid may de-emulsify a bit more. You could also try to break the emulsion with heat. BUT PLEASE BE AWARE that using heat to break emulsions can create a dangerous situation called "explosive bumping." If your emulsion doesn't break, or even if it doesn't break entirely within the realm of 120* - 150*F, discontinue applying heat and seek another method. Otherwise you take the risk of having the emulsion and fuel splattered all over the ceiling, if not scalding anyone within an eight foot radius. Whatever you do..., conduct these tests in small volumes first. One other note, no matter the outcome with this batch. It is a very useful precaution to always conduct a sample washing of your fuel before you submit the entire batch to the wash process, just to insure that the reaction completed. This is as simple as taking 1-2 fluid ounces of fuel and an equal amount of water, adding them into a sealable jar and shaking the bejeebers out of them. If your reaction has gone to completion you should see a separation within quite literally seconds. Please repost whatever results you come up with.
