Abstract A circulating suspended particle-electrode was applied to the electrochemical hydrodimerization of acrylonitrile in order to examine the possibility of scaling up the cell capacity. Total current on a feeder electrode was increased remarkably by an addition of lead particles and the current was proportional to the quantity of lead particles added. Total current was also increased with the increase of circulating speed. The current increased with electrolysis time because the surface oxide was gradually reduced with continuing electrolysis. Contact resistance between a suspended particle and a feeder electrode was not as large as in the Kolbe synthesis on a particulated electrode, and electron transfer between the particle and the feeder electrode at their collision was fast compared with charge transfer on the particle electrode. Current efficiency for adiponitrile formation was less on the suspended electrode than on a plane electrode. However, the rate of adiponitrile formation was markedly increased by the use of the suspended electrode.
