| Sodium hypophosphite Siv thiab Synthesis |
| Chemical Properties | dawb crystalline hmoov los yog tsis muaj xim muaju |
| Siv | Pharmaceuticals, txo tus neeg sawv cev hauv electrode- tsawg nickel plating ntawm plastics thiab hlau, lab reagent, hloov sodium nitrite hauv cov nqaij haus luam yeeb. |
| Cov tshuaj tiv thaiv | Sodium hypophosphite, NaH2PO2 · H2O, dawb khoom, soluble, tsim (1) los ntawm cov tshuaj tiv thaiv ntawm hypophosphorous acid thiab sodium carbonate tov, thiab ces evaporating, (2) los ntawm cov tshuaj tiv thaiv ntawm NaOH tov thiab phosphorus rau cua sov (poisonous phosphine gas evolved). |
| Hazard | Kev puas tsuaj tshwm sim thaum sib xyaw nrog cov tshuaj muaj zog oxidizing, decomposes rau phosphine ntawm cua sov, khaws cia hauv qhov chaw txias, qhuav, deb ntawm cov khoom siv oxidizing. |
| Flammability thiab Explosibility | Tsis yog nplaim taws |
| Kev ruaj ntseg Profile | Tshuaj lom los ntawm txoj kev subcutaneous. Muaj tshuaj lom los ntawm txoj kev intraperitoneal. Flammable thaum raug tshav kub los yog nplaim taws. Cov tshuaj aqueous tuaj yeem tawg thaum evaporation. Muaj feem cuam tshuam nrog oxidants (xws li chlorates, nitrates). Thaum tshav kub kub ua rau nws evolve phosphne. Nws tuaj yeem tawg. Thaum rhuab mus rau decomposition nws emits cov pa phem ntawm POx thiab Na2O. Saib PHOSPHIN |
