A Membrane Separation Process for Biodiesel Purification

membrane separation technology is the size of the glycerol droplets and the influence of other components such as water, methanol and soaps on that droplet size. The effect of water, methanol, soap and glycerol on the size of suspended glycerol droplets in FAME was studied using a 3-level Box-Behnken experimental design technique. Standard

How does CH3S (methanol) react/dissociate in water ...

7/9/2008· CH3S is not the chemical formula of methanol. If it was CH3SH it could be named methyl mercaptane, the sulfur analogon of methanol. CH3-OH is it. If dissociation takes place, the hydrogen attached to the oxygen will separate as a positive ion. CH3-OH --> CH3-O- + H+ . But this will only happen to a significant extend, if strong bases are present.
