    Re: The Imsides method

    I tested glycerol free fatty acid stripping of used vegetable oil. The Used Vegetable Oil titrated at 15 drops that's a titration number of 15/24 milliliters. I treated the U.V.O. with 25% pure...

    Re: The Imsides method

    I've found something a little odd. I tried Smithy's glycerol stripping using pure pharmacy bought glycerine. I heated the used vegetable oil to 110 degrees centigrade. No water boiled out. I...

    Re: The Imsides method

    Free fatty acids don't react with caustic immediately like inorganic reactions do. Some soap forms but it takes time for it all to react.

    Re: The Imsides method

    Smithy I think it's being ignored that glycerol strips used oil of free fatty acids and some water. There is residual catalyst and methanol in the glycerine. I will get some used vegetable oil...

    Re: The Imsides method

    Something you didn't mention Tilly is pretreating vegetable oil with glycerine is ffa's hydrogen bond with glycerine as part of why they go into the glycerine layer and are to an extent removed. ...

    Re: The Imsides method

    Calcium oxide adsorbs , reacts with water, removing water from solution to a great extent in alcohol. Making methoxide solution from potassium or sodium hydroxide produces water and methoxide in...

    Re: The Imsides method

    The organic chemistry class I was in made a methoxide/alcohol type solution in 1985 or so. It involved putting dry/anhydrous alcohol into a flask then adding sodium metal. The metal floated in...

    Re: The Imsides method

    This method seems to me to have a low temperature advantage. I recognize it probably increases methoxide concentration, but with a disadvantage of calcium soaps (probably) being formed that would...

    Re: The Imsides method

    In organic reactions often a general reaction applied to a specific reaction applies to many other similar reactions. Calcium oxide adsorbing water from ethanol probably means it will absorb water...

    Maybe there is a misunderstanding of the term "swamping" with base. Sawamping to me means a great excess, like a tidal wave swamping an area of land. So excess cement adsorbing water from the...

    Re: washing with heat

    Methanol is miscible in biodiesel and glycerine. So demething allows the glycerine in the biodiesel that's dissolved in the methanol to separate. I expect soap also falls out, so the resulting soap...
