    CPC classification number: C25B3/105

    Abstract: Process for the production of adiponitrile by direct electrochemical hydrodimerization of acrylonitrile using a medium containing acrylonitrile, an electrolyte salt, water and, if desired, a solvent at a temperature of from 10* to 60* C. at a pH of from 1 to 10. In the process, electrolysis is carried out in a cell having a liquid cathode which is contacted by a solid anode which is not wetted by the liquid cathode or into which the solid anode is immersed to a depth of up to 20 mm. Adiponitrile is an important intermediate for synthetic fiber manufacture.

    Abstract: LAYERS OF AN OXIDE MIXTURE OF AT LEAST ONE PLATINUM METAL AND OXIDES OF THE ELEMENTS SILICON, TIN OR GERMANIUM ARE APPLIED TO A CORE OF AN ANODICALLYS TABLE MATERIAL FOR THE PRODUCTION OF ACTIVATED ELECTRODES. FOR THIS PURPOSE, SILICON, TIN OR GERMANIUM OR A COMPOUND THEREOF WITH THE PLATINUM METAL OR A COMPOUND THEREOF IS CONVERTED INTO OXIDIC COMPOUNDS AND THESE ARE FIXED ONTO THE SURFACE OF THE ANODICALLY STABLE MATERIAL OBY THERMAL TREATMENT.

    Abstract: Production of adiponitrile by direct electrochemical hydrodimerization of acrylonitrile in a medium which contains acrylonitrile, and electrolyte salt, water and, if desired, a solvent at a temperature of from 10* to 60* C. and a pH value of from 1 to 10 using liquid-impermeable electrodes. The medium is passed through the pairs of electrodes which are 0.05 to 2 mm. apart. Adiponitrile is an important intermediate for synthetic fiber manufacture.
