ABSTRACT:
Process for obtaining guanidine carbonate from aqueous solutions in which it is present with urea and its pyrolysis products as well as ammonia and carbon dioxide, which comprises heating the aqueous solution to a temperature of at most 80.degree.C at atmospheric pressure, evaporating the resulting solution, which contains an amount of carbon dioxide equal to the guanidine content, until it is saturated with urea, separating the solid precipitate, suspending the mother liquor in liquid ammonia and separating the resulting guanidine carbonate.
