Obtaining trisodium phosphate by exchange decomposition of ammophos with soda ash

Abstract

Based on the results of experimental studies, a method for producing trisodium phosphate monohydrate, which has a low bulk density and a high hygroscopicity point, has been developed. The results of a study of the physicochemical parameters of obtaining trisodium phosphate by neutralization of ammophos with soda ash and sodium hydroxide are presented. The data on the physicochemical parameters of the processes of exchange decomposition of ammophos with soda ash followed by neutralization with sodium hydroxide are given.
