Abstract
Inventia se refera la un procedeu pentru sinteza hidrazobisciclohexancarbonitrilului, prin reactia ciclohexanonei cu hidratul de hidrazina în mediu apos, în prezenta de acizi minerali, de exemplu acidul sulfuric, acidul ortofosforic, acidul clorhidric si cianuri alcaline. Lucrînd la anumite raporturi molare între reactanti, în conditii de reactie stabilite, se obtin randamente ridicate în hidrazobisciclohexancarbonitril, raportate la hidratul de hidrazina.
