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.
