| abstract | PURPOSE: To obtain phosphate contg. sodium tripolyphosphate and sodium pyrophosphate in an arbitrary ratio by regulating the molar ratio of Na to P to a specified range when phosphoric acid is allowed to react with sodium hydroxide or other sodium salt. n CONSTITUTION: When phosphoric acid is allowed to react with sodium hydroxide and/or other sodium salt, the molar ratio of Na to P is regulated to 1.7-2.0 and the resulting product is dried and calcined to obtain phosphate contg. sodium tripolyphosphate and sodium pyrophosphate in an arbitrary ratio. The sodium salt used may be sodium carbonate, sodium hydrogencarbonate, sodium prim. phosphate, sodium sec. phosphate or sodium tert. phosphate but sodium hydroxide is preferably used from the viewpoint of work efficiency and handleability. Commercially available 75% H 3 PO 4 or 85% H 3 PO 4 is preferably used as the phosphoric acid (H 3 PO 4 ) and the concn. may be regulated as required. n COPYRIGHT: (C)1991,JPO&Japio |
