Abstract
Inventia de fata descrie procedeul pentru sinteza azobisciclohexancarbonitrilului prin reactia de oxidare a hidrazobisciclohexancarbonitrilului cu hipoclorit de sodiu solutie apoasa continînd 8...12% clor activ, în prezenta de acid sulfuric si initiatori din clasa bromurilor metalelor alcaline cum sînt bromura de sodiu si bromura de potasiu. Reactia de oxidare are loc în conditii specifice de temperatura si durata, conducînd la randamente cuprinse între 80 si 90% de azobisciclohexancarbonitril, raportate la hidrazobisciclohexancarbonitril. Produsul are un grad ridicat de puritate.The present invention describes the process for the synthesis of azobisic cyclohexanecarbonitrile by the oxidation reaction of hydrazobis-cyclohexanecarbonitrile with sodium hypochlorite aqueous solution containing 8-12% active chlorine in the presence of sulfuric acid and initiators of the alkali metal bromide class such as sodium bromide and potassium. The oxidation reaction takes place under specific temperature and duration conditions, resulting in yields ranging from 80 to 90% of azobisocyclohexanecarbonitrile, relative to hydrazobiciclohexanecarbonitrile. The product has a high degree of purity.
