Abstract
High current efficiency can be obtained in an electrolytic cell by inducing turbulence in the catholyte preferably by utilizing a gas-directing cathode and cation-permselective membrane combination. There is disclosed a process for electrolysis, particularly, the electrolysis of an alkali metal chloride such as sodium chloride to produce chlorine and sodium hydroxide. Said cell has a cathode and an anode divided into catholyte and anolyte compartments by a cation-permselective membrane. Turbulence inducing means such as a gas-directing cathode provides turbulence in said catholyte at the surface of said membrane by directing gas evolving on said cathode toward or away from said membrane. Multicell arrangements are also disclosed wherein said cells are connected in series.
