For products of vegetable oil for biodiesel conversion?

How do you dispose of wastewater from the screening stage of the conversion of biodiesel and other byproducts that accompany the conversion of vegetable oil for biodiesel

Wastewater? Most reactions biodiesel are sensitive to water and will not proceed if water is present. Biodiesel conversions are sensitive to water because they are usually catalyzed by bases such as NaOH and Na-methoxide. There should be no waste water unless it is absorbed through the atmosphere after the reaction is complete. The main byproduct of the transesterification is glycerin. Glycerin is used in cosmetics and often turns into glycerol carbonate, which has more uses. I just checked out daddeeo's source. No way that NaOH and methanol react to give sodium methoxide unelss add an extreme excess of NaOH. Sodium methoxide is highly reactive and is much stronger hella of a database NaOH. This means that the reaction is favored in the reverse direction. Who has published that article is wrong. They think that sodium methoxide is to catalyze the reaction, but its actually being done NaOH catalysis. If you used the method described in the article that would actually generate water on the formation of sodium methoxide, but I'm sure this is not the case. Sodium methoxide reacts violently with water to emit toxic gases, flammable, but no. When solubilize NaOH in methanol is doing just that, solubilize that no production of methoxide … the rxn runs in the reverse direction. Moreover, water that is allegedly generated react with the rest of NaOH and saponified, producing soap. The catalyst in the article is NaOH, NaOMe not.
