Abstract
Inventia descrie un procedeu pentru sinteza azobisizobutironitrilului prin reactia acetomciamhidrinei cu diclorhudratatul de hidrazina, în prezenta sau în absenta de hidroxizi alcalini, în mediul apos, iar oxidartea produsului intermediar efectuîndu-se cu apa oxigenata 30% în prezenta de bromuri de metale alcaline si acid sulfuric, de hidracizi cum este acidul bromhidric si acid sulfuric, în anumite conditii de temperatura si timp de contact între reactanti. Prin procedeul descris se poate sintetiza azobisizobutironitrilul cu randamente mari aproximativ 90% raportate la diclorhidrat de hidrazina si acetoncianhidrina.
