Abstract

PURPOSE: To prepare a guanidine salt, easily, without using ammonia, by using a specific aqueous solution as an elutant of crude guanidine adsorbed to a cation exchange material.
CONSTITUTION: A solution containing guanidine or a guanidine salt is treated with an anion exchanger to adsorb the guanidine or its salt. The adsorbed guanidine, etc. is eluted with water containing CO2, and an aqueous solution of guanidine carbonate is obtained as elute. The solution thus obtained is neutralized with an acid other than carbonic acid, e.g. phosphoric acid, to obtain the quanidine salt of the acid. The process is more economical than cnventional method using an aqueous solution of (NH4)2CO3 as elutant wherein the ammonia-regeneration procedure is indispensable.
