ABSTRACT:
The electrolysis of brine in electrolytic chlor-alkali diaphragm cells is performed using polymeric fluorocarbon-bonded mixtures of chrysotile asbestos and crocidolite asbestos as the diaphragm material. These diaphragms are particularly effective in permitting operation of the cells at low pH, thereby extending the life of graphite anodes.
