Process using an oxidant depolarized solid polymer electrolyte chlor-alkali cell

摘要

Disclosed is the ultrasonic treatment of a solid polymer electrolyte to dislodge reaction products. Also disclosed is the use of an amide anodic surface to provide a hydrophobic surface. Disclosed is a SPE chlor-alkali cell having COOH p.i.m., and oxidation of the catholyte. The catholyte oxidant may be a peroxy compound, or it may be carried by an oxygen bearing particle. Alternatively, it may be a redox couple. Catalysts are disclosed. The use of an Si bipolar unit is disclosed.
