description This invention relates to a process of producing oxyacids of chlorine or salts of such acids by an electrolysis of salt solutions which are contaminated with calcium and/or magnesium or of sea water. In such processes, deposits or crusts are formed on the electrodes in the course of time, particularly in the cells to which the sea water is supplied first. For this reason, the plant must be cleaned from time to time. By means of the invention, a formation of crusts is virtually prevented in that the electrolysis is carried out (a) in an initial phase with an electrolyte flowing at a velocity above 0.7 meter per second and up to 2.0 meters per second and (b) in a succeeding phase with an electrolyte flowing at a velocity of 0.3 meter per second to less than 0.7 meter per second, the velocity of flow being stated for electrolyte which is free from gas.
