Abstract
Inventia se refera la un procedeu de preparare a hidrazodicarboxamidei prin reactia ureei cu fosfatul de hidrazina în prezenta sau absenta de hidroxizi alcalini cum sînt hidroxidul de sodiu si hidroxidul de potasiu, lucrînd la numite rapoarte molare între reactanti si în conditii specifice de temperatura si timp de contact, care permit obtinerea de randamente mari în hidrazodicarboxamida, raportate la uree.The invention relates to a process for the preparation of hydrazodicarboxamide by reacting urea with hydrazine phosphate in the presence or absence of alkali hydroxides such as sodium hydroxide and potassium hydroxide, working in so called molar ratios between the reactants and under specific conditions of temperature and time contact, which allow for high yields in the hydrazodicarboxamide, relative to urea.
