Kugwiritsa Ntchito: Chowonjezera cha Chakudya cha Zinyama kapena Mankhwala
Sodium iodide ndi chinthu choyera chomwe chimapezeka kudzera mu njira yolumikizirana pakati pa sodium carbonate ndi hydroiodic acid ndi kusungunuka kwa madzi. Pali mankhwala a anhydrous, dihydrate ndi pentahydrate. Ndi chinthu chopangira ayodini, chogwiritsidwa ntchito mu zamankhwala ndi kujambula zithunzi. Sodium iodide solution, chifukwa cha kupanga hydroiodic acid, imasonyeza mphamvu yochepetsera.
Katundu wa Zogulitsa
Sodium iodide ndi ufa wa kristalo woyera wopanda mtundu kapena wonyezimira. Ndi wopanda fungo ndipo kukoma kwake ndi mchere kumakhala kowawa. Imatenga chinyezi kuchokera mumlengalenga; pang'onopang'ono imasintha bulauni ikakumana ndi mpweya chifukwa cha ayodini yomwe yasinthidwa; kuchuluka kwake ndi 3.67g/cm3; imasungunuka pa 660°C; imasungunuka pa 1,304°C; kuthamanga kwa nthunzi 1 torr pa 767°C ndi 5 torr pa 857°C; imasungunuka kwambiri m'madzi, 178.7 g/100 mL pa 20°C ndi 294 g/100 mL pa 70°C; imasungunuka mu ethanol ndi acetone.
Kugwiritsa ntchito
Sodium iodide imagwiritsidwa ntchito kwambiri posinthana kwa halide (Finkelstein reaction), mwachitsanzo posintha alkyl chloride, allyl chloride ndi arylmethyl chloride kukhala ma iodide awoawo, omwe ndi oyambira mankhwala ndi mankhwala abwino. Amagwiritsidwa ntchito kupititsa patsogolo luso la kupanga ma Wittig adducts kuchokera ku ma chloride ndi ma bromides osagwira ntchito kwambiri. Makonzedwe oyenera amagwiritsidwa ntchito ngati chowonjezera cha michere. Sodium iodide imagwiritsidwa ntchito ngati choyambira cha wowongolera mu ab initio emulsion polymerization. Sodium iodide imagwiritsidwa ntchito pozindikira mpweya wosungunuka mu njira yosinthidwa ya Winkler, kupanga utoto wa fluorescent coppersensor-1 (CS1) pojambula maiwe amkuwa a labile mu zitsanzo zamoyo, komanso kugawanika kwa ma esters, lactones, carbamates ndi ethers kuphatikiza ndi chlorotrimethylsilane.
Ingagwiritsidwe ntchito pojambula chotupa, retrograde urography, cholangiography kudzera mu T-tube ndi fistula angiography ya ziwalo zina.
Urography: 6.25% 100ml. Cystography: 6.25% 150ml. Retrograde pyelography: 12.5% 5~7ml. T-tube cholangiography: 12.5% 10~30ml. Fistula angiography: kudziwa malo obayira jakisoni ndi mlingo wake malinga ndi momwe matenda alili.
Sodium iodide idagwiritsidwa ntchito ngati gawo lokonzekera yankho la Mayer's hematoxylin stain.
Ikhoza kugwiritsidwa ntchito m'njira zotsatirazi:
Choyambitsa polima ya butyl acrylate.
Wothandizira wa chaotropic pakutulutsa DNA.
Choletsa chitetezo pochotsa gulu la N-tert-butyloxycarbonyl mu amino acid.
Chotsukira madzi chosungunula kuwala.
Kulongedza ndi Kusunga
Kulongedza: Katoni ya ng'oma yokhala ndi thumba la pulasitiki, 25KG/ng'oma.
Kusungira: Kutsekedwa ndi kusungidwa mumdima.
