摘要

Aqueous composition, obtained by preparing a mixture of water and guanidine phosphate; adjusting the pH value of the mixture to 4.5-6.5 at 20[deg]C; adding ammonium sulfamate or amidosulfonic acid, or adding a mixture to both products; optionally adjusting the pH value of the received mixture to 4.5-6.5 at 20[deg]C; and adding ammoniumsulfate. Aqueous composition, obtained by (a) preparing a mixture from water and guanidine phosphate, where the quantity ratio is selected such that the mixture possesses a phosphorous content of 4-6.5 wt.%; (b) adjusting the pH value of the mixture to 4.5-6.5 at 20[deg]C; (c) adding ammonium sulfamate or amidosulfonic acid in a quantity, such that per 100 g after step (b) receives a mixture of amidosulfonic acid (8-12 g) or ammoniumsulfamate (9.5-15 g), or adding a mixture to both products; (d) optionally adjusting the pH value of the received mixture to 4.5-6.5 at 20[deg]C; and (e) adding ammoniumsulfate in such a quantity that per 100 g of that after step (d) receives a mixture of ammoniumsulfates (20-40 g).
