Abstract

Sposób otrzymywania mieszanek wielofosforanowych zawierających 10-90% wagowych trifosforanu pentasodu, 3-10% wagowych difosforanu tetrasodu i 5-15% wagowych diwodorofosforan disodu polega na tym, że do stężonego kwasu fosforowego termicznego, dodaje się stopniowo, przy ciągłym mieszaniu i rozcieraniu, sodę amoniakalną lub węglan potasu, przy stosunku molowym Na/P od 1,67 do 1,77 by otrzymać produkt o sypkiej konsystencji korzystnie konsystencji mokrego piasku, po czym otrzymaną mieszaninę kalcynuje się.The method of obtaining polyphosphate mixtures containing 10-90% by weight of pentasodium triphosphate, 3-10% by weight of tetrasodium diphosphate and 5-15% by weight of disodium dihydrogen phosphate consists in gradually adding soda to concentrated thermal phosphoric acid, with constant mixing and grinding. ammonia solution or potassium carbonate, with a Na/P molar ratio of 1.67 to 1.77 to obtain a product with a loose consistency, preferably the consistency of wet sand, and then the obtained mixture is calcined.
