Abstract
The operation of electrolytic cells employing ion exchange membranes is improved by addition to the catholyte of a fluorinated ionomer resin resulting in a long-term reduction in the operating voltage of the electrolytic cell.
Claims11
In a process for the electrolysis of a solution in an electrolytic cell which comprises an anode, a cathode, an anode compartment, a cathode compartment, and a fluorine-containing ion exchange membrane which separates said compartments, where the improvement comprises adding fluorinated ionomer resin to said cathode compartment.
The process for electrolysis of a solution in an electrolytic cell which comprises an anode, a cathode, an anode compartment containing an anolyte, a cathode compartment containing a catholyte, and a fluorine-containing ion exchange membrane which separates said compartments, comprising adding to the catholyte sufficient amounts of a fluorinated ionomer resin to reduce cell voltage.
