Abstract

Inventia se refera la un procedeu de obtinere a hidrazodicarboxamidei prin reactia ureei cu monoclorhidratul de hidrazina sau diclorhidratul de hidrazina, în prezenta sau absenta de hidroxizi alcalini cum sînt hidroxidul de sodiu si hidroxidul de potasiu, ca atare sau luati în amestec, lucrînd în mediu apos, la anumite rapoarte molare între reactanti, la timp de contact determinat, la temperaturi cuprinse între 100 si 130 degree C, obtinînd randamente cuprinse între 70 si 90%, raportate la clorhidrat de hidrazina.The invention relates to a process for the preparation of hydrazodicarboxamide by reacting urea with hydrazine monohydrochloride or hydrazine dihydrochloride in the presence or absence of alkali hydroxides such as sodium hydroxide and potassium hydroxide as such or mixed in an aqueous medium , at certain molar ratios between the reactants, at defined contact time, at temperatures between 100 and 130 degrees C, yielding between 70 and 90% yields relative to hydrazine hydrochloride.
