Abstract

Inventia descrie un procedeu pentru obtinerea azodicarboxamidei prin reactia hidrazodicarboxamidei cu bicromat de sodiu, în prezenta de saruri ale acizilor hipohalogenosi cu metalele alcaline, cum sunt hipocloritul de sodiu, hipocloritul de potasiu, hipobromitul de sodiu si hipobromitul de potasiu si în prezenta de acid sulfuric, în mediu apos, la temperaturi cuprinse între 10 si 20 degree C, la timp de contact între 1 si 5 h la presiune atmosferica.The invention describes a process for obtaining azodicarboxamide by reacting hydrazodicarboxamide with sodium dichromate in the presence of alkaline earth metal salts of hypochaloxo acids such as sodium hypochlorite, potassium hypochlorite, sodium hyobromite and potassium hyobromite and in the presence of sulfuric acid, in an aqueous medium at temperatures between 10 and 20 degrees C, at a contact time of 1 to 5 hours at atmospheric pressure.
