I-sodium iodide yinto emhlophe efumaneka ngokusabela phakathi kwe-sodium carbonate kunye ne-hydroiodic acid kunye nokuphuma komphunga ngakumbi kwesisombululo. Kukho i-anhydrous, i-dihydrate kunye ne-pentahydrate compound. Yinto esetyenziswayo ekuveliseni i-iodine, ukuze isetyenziswe kunyango nakwifoto. Isisombululo se-asidi se-sodium iodide, ngenxa yokuveliswa kwe-hydroiodic acid, sibonisa amandla okunciphisa.
Iipropati zeMveliso
I-sodium iodide yikristale yetyhubhu engenambala okanye umgubo omhlophe wekristale. Ayinavumba kwaye inencasa yetyuwa ekrakra. Ifunxa umswakama emoyeni; ijika kancinci ibe mdaka xa ichaphazeleka emoyeni ngenxa ye-iodine eguqukileyo; ubuninzi bayo yi-3.67g/cm3; iyanyibilika kwi-660°C; iyanyibilika kwi-1,304°C; uxinzelelo lomphunga yi-torr enye kwi-767°C kunye ne-torr ezi-5 kwi-857°C; iyanyibilika kakhulu emanzini, yi-178.7 g/100 mL kwi-20°C kunye ne-294 g/100 mL kwi-70°C; iyanyibilika kwi-ethanol kunye ne-acetone.
Isicelo
I-Sodium iodide isetyenziswa kakhulu ekutshintshiseni i-halide (i-Finkelstein reaction), umzekelo ekuguquleni i-alkyl chloride, i-allyl chloride kunye ne-arylmethyl chloride zibe zii-iodides zazo, ezizii-precursors zeemveliso zamayeza kunye neekhemikhali ezintle. Zisetyenziselwa ukuphucula ukusebenza kakuhle kokwenziwa kwee-Wittig adducts ezivela kwii-chloride kunye nee-bromides ezingasabeliyo kakhulu. Amalungiselelo afanelekileyo asetyenziswa njengesongezelelo sezondlo. I-Sodium iodide isetyenziswa njengesandulela se-arhente yokulawula kwi-ab initio emulsion polymerization. I-Sodium iodide isetyenziswa ekumiselweni kwe-oxygen enyibilikisiweyo kwindlela ye-Winkler eguquliweyo, ukwenziwa kwe-fluorescent dye coppersensor-1 (CS1) yokucinga ngamachibi e-copper alabile kwiisampuli zebhayoloji, kunye nokuqhekeka kwee-esters, ii-lactones, ii-carbamates kunye nee-ethers kunye ne-chlorotrimethylsilane.
Ingasetyenziselwa i-cystography, i-retrograde urography, i-cholangiography nge-T-tube kunye ne-fistula angiography yezinye iindawo.
I-Urography: 6.25% 100ml. I-Cystography: 6.25% 150ml. I-Retrograde pyelography: 12.5% 5~7ml. I-T-tube cholangiography: 12.5% 10~30ml. I-Fistula angiography: misela indawo yenaliti kunye nomthamo ngokwemeko yesifo.
I-sodium iodide isetyenziswe njengenxalenye ekulungiseleleni isisombululo se-hematoxylin stain seMayer.
Ingasetyenziswa kwezi nkqubo zilandelayo:
I-precursor kwi-polymerization ye-butyl acrylate.
I-arhente ye-chaotropic ekukhutshweni kwe-DNA.
Iarhente yokususa ukhuseleko ekususweni kweqela le-N-tert-butyloxycarbonyl kwii-amino acids.
I-reagent yokucima i-fluorescence enyibilikayo emanzini.
Ukupakisha kunye nokugcina
Ukupakisha: Idrama yekhadibhodi efakwe ingxowa yeplastiki, 25KG/idrama.
Indawo yokugcina: Ivaliwe kwaye igcinwe ebumnyameni.
