METHOD OF ELECTROCHEMICAL HYDRODIMERIZATION OF OLEFINIC COMPOUNDS

A method of electrochemical dimerization of olefinic compounds of the general formula CH2=CHX, wherein X is a nitrile, ester, amide, aldehyde or carboxy group, according to which a mixture consisting of an aqueous solution of acid salts of an alkali metal and polybasic acid and olefine is subjected to electrolysis in an electrolytic cell provided with an oxide anode and with a cathode made of graphite impregnated with ion-exchange polymers that are insoluble in the reaction mixture and contain a tetraalkylammonium group or a substituted tetraalkylammonium group, the electrolysis being effected at a cathode current density of 300-1,600 A/m2, a pH of 7-9, and at a temperature of 17 DEG -25 DEG C.
