    This is an incredible claim to make.
    I am sure you have carefully performed a test series that allows you to make such a breath-taking claim for your method.
    Please provide, in detail, the testing you performed and the results you achieved that allows you to make this amazing claim.



    4. If the reaction is incomplete, then heating it more will work with the Dr Pepper method, as it is a method that requires heating.
    This is simply an incorrect statement about the Dr Pepper method requiring heating.
    As has been shown many times, with any single stage base procedures including the World Famous Doctor Pepper Technique (Pat Pend), as long as everything remains liquid, the temperature the reaction is performed at is not a limiting factor to the results achieved

    I have a conversion graph that does not agree with your statement..
    According to the graph, while monglycerides never exceed about 7% of the total mass of the oil during the reaction, diglycerides are a very different story.
    At the point where the conversion to methylesters has reached about 46%, both the triglycerides and diglycerides are about 26% of the mass of the oil with the monoglycerides being the remainder.
    As Conversion increases the amount of triglycerides and diglycerides decrease pretty much together in the same ratio while monoglycerides never exceed about 7% of the total.

    At about 46% conversions the combined mass of the monoglycerides and diglycerides exceeds that of the triglycerides and this does not change all the way to completion.

    Tilly,
    In the interest of open communications, can you please provide references (or better still, a URL of where it is located) for the graph you mentioned in the above post?

    Thank you

    Life is a journey, with problems to solve, lessons to learn, but most of all, experiences to enjoy.

    '2014 Toyota Prius (on ULP)


    Previous Vehicles:
    '90 Mazda Capella. (2000 - 2003) My first Fatmobile. Converted to fun on veggie oil with a 2 tank setup. Died when supercharger stuck at max boost for weeks. Stretched head bolts.
    '80 Mercedes 300D. 2 tank conversion [Sold]
    '84 Mercedes 300D. 1 tank, no conversion. Replaced engine with rebuilt OM617A turbodiesel engine. Finally had good power. Donor for current Fatmobile coupe. (body parted out and carcass sold for scrap.)

    I knew some one would ask that question.

    I made several photo copies of the graph years ago when Neutral told me it existed. At the time I spent several hours searching the internet and finally found it.
    Of course I noted the site where I found the graph.
    Unfortunately, when I checked back today, I discovered that the original site I got it from no longer exists.

    I have spent some time today attempting to relocate the graph, and I am happy to say that I did relocate it.
    It is fig 1 page 1639

    More information here, graphs from mathmatical models that also don't seem to agree with Mark about the mono,Di and Tri distribution.

    I was doing a bit of light research today and I found the following post in the "New Methods #2. The Imisides Method" Thread on the Infopop forum posted by "Minder", one of your several Nom-de-plum's which said;
    "To answer this specific question, if you got soap in the batch, it's because the oil wasn't dry. This method is anhydrous, and will work best with dry oil.
    I once got lazy with this, but never again. I had a batch that I knew had some water in the oil, but went ahead anyway. The result was that the method didn't proceed at room temperature - a bit of a problem when you make 1000L at a time."
    http://biodiesel.infopop.cc/eve/foru...083#8977047083

    So it would appear that, contrary to your above claim, along with every other single Stage Base procedure, your method does require dry oil
