Chemical Properties
white; hygroscopic; crystal(s) powder(s); used as an antidote to mercuric chloride poisoning [HAW93] [MER06]
Uses
Sodium Metaphosphate can be used as a catalyst for polyester synthesis.
Production Methods
Disodium phosphonate is commercially produced by a process that involves dissolving phosphonic acid in water and gradually adding sodium hydroxide to achieve the disodium salt form. This reaction is exothermic and typically conducted at ambient temperatures with pH monitoring to ensure complete neutralisation.
Flammability and Explosibility
Non flammable
Mechanism of action
Contact activity with some protective action
