Abstract
Disclosed is an electrolytic process using a horizontal type cation exchange membrane electrolytic cell in which catholyte liquor is supplied into a cathode compartment with initial linear velocity of at least 8 cm/sec and gas content of at most 0.6 at a catholyte liquor outlet. Also disclosed is an electrolytic cell used for the foregoing process. The invention enables not only conversion of a mercury electrolytic cell to a cation exchange membrane electrolytic cell with low cost, but the long-term and stable operation.
