Abstract

PURPOSE: On the production of title compound, a flame retarder, through the reaction between dicyandiamide and acidammonium salt by melting together, ammonium sulfamate is added to inhibit remarkably side reactions, thus increasing the yield and facilitating the recovery of the product.
CONSTITUTION: Dicyandiamide and an inorganic acid ammonium salt are melted together to form said guanidine inorganic acid salt werein ammonium sulfamate is incorporated to the reaction system.
EFFECT: The yield is raised from about 65% to about 90% and the by-products reduce to 1/3 . The sulfate and sulfamate ions can be readily removed from the resulting guanidine sulfate containing guanidine sulfamate in the form of its alkaline earth salt that is hard soluble in water.
