Electrochemistry Mercury cathode cells

The use of electrochemistry to convert propylene to the oxide was researched in particular by Bayer and Kellogg. In this method, propylene is injected in the neighborhood of the anode of a sodium chloride electrolysis cell with a mercury athode (see Section 11.2.5.ZB). The hypochlorous add formed with the chlorine liberated at the anode is added to the propylene. The chlorohydrin obtained is hydrolysed at the cathode by the caustic produced by the action of water on the amalgam. Propylene oxide is separated from the mixture by stripping, while the. sodium chloride is returned to the electrolyser. The overall reaction is as follows ...
