> Can anyone answer these questions please > How much Glycerine% is produced from WVO, how / why does this % vary? Martin, The glycerine yield is approximately the same volume as the methoxide used. A little less because the reaction results in a slight reduction in total volume. High levels of NaOH (above titration figure) will decrease BD yield and increase the volume of lower layer. Could not say for sure if this is all glycerine however. > How much Methanol is in the Glycerine? From memory the reaction consumes 140ml of methanol per litre of WVO. (check). Excess is usually used to push the reaction in the desired direction. Methanol is insoluble in BD but soluble in glycerine. > Is anybody recovering the Methanol from Glycerine? There is much discussion of inclusion of methanol recovery systems in reactor designs, but little talk of using recovered methanol within this group at present. A search of the archives could reveal more information. Am currently working on chemical means to recover the methanol. > What do you do with this Glycerine? - UK based question. Uses range from soapmaking to cleaning paintbrushes to handcleaner (with methanol removed) etc. Apparently there is a market for high grade glycerol but refining it to that stage is expensive.
