Abstract
Prezenta inventie se refera la un procedeu pentru obtinerea hidrazindicarboxamidei. Procedeul, conform inventiei, are la baza ca substante primare ureea si NaHCO3 supuse, în prealabil, unui proces fizic de dozare si amestecare, dupa care amestecul este tratat termic într-un cuptor în care se realizeaza sinteza NaNCO, tratat apoi cu sulfat de hidrazina.
