Abstract
PURPOSE: To obtain a N,N'-disubstituted 4,4'-bipyridinium salt useful as herbicides stably for a long time continuously, by electrolyzing a N-substituted bipyridinium salt, using a specific electrolytic cell having two types of diaphragms between the cathode and anode.
CONSTITUTION: A N-substituted pyridinium salt, preferably lower alkyl substituted pyridinium salt, such as N-methylpyridinium salt, is fed to the canode compartment and electrolyzed while feeding an alkali, e.g. sodium hydroxide, to the anode compartment, by using an electrolytic cell comprising the anode isolated by an anionic exchange resin diaphragm, the anode compartment isolated by a cationic exchange resin diaphragm and an intermediate compartment, to give a N,N'-disubstituted 4, 4'-bipyridinium salt continuously. Preferably, an inorganic material, e.g. platinum or copper, resistant to the anode product is used as the anode, and lead or mercury, having a high hydrogen overvoltage is used as the cathode.
