Abstract
Inventia se refera la un procedeu de obtinere a azobisizobutironitrilului prin oxidarea hidrazobisizobutironitrilului cu bicromatde sodiu în mediu apos, în prezenta de saruri ale acizilor hipohalogenati cu metalele alcaline ca agenti de initiere, cum sunt hipocloritul de sodiu, hipocloritul de potasoi, hipobromitul de sodiu si hipobromitul de potasiu si în prezenta de acid sulfuric. Reactia se efectueaza la temperaturi cuprinse între 5 si 30 degree C, la presiunea atmosferica, la timp de contact între 1 si 6h, cu omogenizarea eficienta a mediului de reactie.The invention relates to a process for the preparation of azobisisobutyronitrile by oxidation of hydrazobisisobutyronitrile with sodium bicarbonate in aqueous medium, in the presence of alkaline metal hypochalcane salts as initiating agents such as sodium hypochlorite, potassium hypochlorite, sodium hypobromite and hypobromite potassium and in the presence of sulfuric acid. The reaction is carried out at temperatures ranging from 5 to 30 degrees C at atmospheric pressure over contact time between 1 and 6 hours with the efficient reaction homogenization.
