manufactured by the non-dimerizing electroreduction of acrylonitrile.
Thermodynamic calculations, kinetic studies, laboratory-scale preparative
syntheses, and technological considerations made it possible to apply the
electrochemical PN manufacturing on the pilot plant scale. As PN formation is
kinetically favoured over adiponitrile, the yield of PN raises with increasing
current densities. Endurance tests are reported for a continuous operation of
the pilot plant over 7-days. Over this time period the specific material
consumptions is of 1.12 kg AN (kg PN)-1, while the power usage is
4.73 kWh kg-1 The annual productivity of this type of plant is 6.53
x 103kg.</span
