description Inventia de fata prezinta procedeul pentru prepararea azobisciclohexancarbonitrilului prin condensarea ciclohexanonei cu sulfatul de hidrazina si cianura de sodiu sau de potasiu în mediu apos si oxidarea produsului intermediar cu bicromat de sodiu în prezenta de acid sulfuric si apa oxigenata sau bromuri alcaline, lucrînd în conditii specifice de temperatura, timp, mediu de reactie. Se obtine azobisciclohexancarbonitrilul cu randamente mari (peste 80%) raportat la hidrazobisciclohexancarbonitril.
