Abstract
Inventia descrie un procedeu de obtinere a azobisizobutironitrilului prin oxidare a hidrazobisizobutironitrilului folosind ca agent de oxidare bicromatul de potasiu si lucrand în mediul apos, în prezenta de saruri ale acizilor hipohalogenosi cu materiale alcaline , cum sunt hipocloritul de sodiu, hipocloritul de potasiu, hipobromitul de sodiu si hipobromitul de potasiu si în prezenta de acid sulfuric. Reactia decurge în conditii specifice de temperatura, timp de contact, rapoarte molare între reactanti. Se obtin randamente mari în produsul principal de oxidare.The invention describes a process for the preparation of azobisisobutyronitrile by oxidation of hydrazobisisobutyronitrile using potassium dichromate as an oxidizing agent and working in the aqueous medium in the presence of alkaline earth metal salts of hypochaloxone acids such as sodium hypochlorite, potassium hypochlorite, sodium hyobromite and potassium hypobromite and in the presence of sulfuric acid. The reaction takes place under specific conditions of temperature, contact time, molar ratios between the reactants. High yields are obtained in the main oxidation product.
