Abstract

Inventia descrie un procedeu de sinteza a hidrazodicarboxamidei prin reactia de condensare a ureei cu hidratul de hidrazina, conform inventiei principale cu descrierea 90402, în prezenta de acid mineral, folosind anumite rapoarte molare între reactanti si efectuînd reactia în anumite conditii de temperatura si timp de contact care permit obtinerea de randamente ridicate de hidrazodicarboxamida, raportate la hidrat de hidrazina.The invention describes a process for the synthesis of hydrazodicarboxamide by the urea condensation reaction with hydrazine hydrate according to the main invention to Description 90402 in the presence of mineral acid using certain molar ratios between the reactants and performing the reaction under certain temperature and contact conditions which allow obtaining high yields of hydrazodicarboxamide relative to hydrazine hydrate.
