    Re: The Imsides method

    In drying ethanol rather than methanol, a chemistry reference book I have says allow overnight at reflux temperature to absorb all but 0.5% of the water from ethanol. I believe the claim was made that an advantage to this Dr. Mark method was room temperature reaction, without heating. Initially calcium oxide was the material not cement. Calcium oxide is harder to get than cement here. Calcium oxide somewhat forcefully bonds with water removing it from solution, theoretically increasing the methoxide concentration. But if the starting material vegetable oil has water in it the advantage is lost. I don't follow maitrang7995 post. Is that name oriental?
