Aminoguanidine bicarbonate with particular properties and method for making same
摘要:
The invention concerns a method for making aminoguanidine bicarbonate from an aqueous solution of cyanamide and an aqueous solution of hydrazine in the presence of CO2. The invention is characterised in that it consists in proceeding with an amount of cyamide slightly higher than the stoichiometric quantity. The invention also concerns quasi-spherical agglomerates of aminoguanidine bicarbonate crystals.
