| | Phosphonic acid, disodium salt Usage And Synthesis |
| 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 | | Pesticide Type | Fungicide |
