Incazelo Yomkhiqizo
Igama lomkhiqizo: I-Sodium Iodide
Inombolo ye-CAS: 7681-82-5
MF: NaI
Izinga Elijwayelekile: Izinga Lokudla, Izinga Lezimboni, Izinga Lemithi, Izinga Le-Reagent
Ubumsulwa: 99% Min
Ukubukeka: Ikristalu Elimhlophe noma I-Powder
Isicelo: Isengezo Sokudla Kwezilwane noma Ikhemisi
I-Sodium iodide iwuketshezi olumhlophe olutholakala ngokusabela phakathi kwe-sodium carbonate ne-hydroiodic acid kanye nokuhwamuka okwengeziwe kwesisombululo. Kukhona i-anhydrous, dihydrate kanye ne-pentahydrate compound. Iwuhlobo lwezinto zokusetshenziswa zokukhiqiza i-iodine, ukuze isetshenziswe kwezokwelapha kanye nezithombe. Isixazululo se-acidic se-sodium iodide, ngenxa yokukhiqizwa kwe-hydroiodic acid, sibonisa ikhono lokunciphisa.
Izakhiwo Zomkhiqizo
I-Sodium iodide iyikristalu eliyi-cubic elingenambala noma i-white crystal powder. Ayinaphunga futhi inokunambitheka okunosawoti okubabayo. Imunca umswakama emoyeni; iphenduka kancane ibe nsundu lapho ithola umoya ngenxa ye-iodine eguquliwe; ubuningi obungu-3.67g/cm3; iyancibilika ku-660°C; iyahwamuka ku-1,304°C; umfutho womusi u-1 torr ku-767°C kanye no-5 torr ku-857°C; iyancibilika kakhulu emanzini, u-178.7 g/100 mL ku-20°C kanye no-294 g/100 mL ku-70°C; iyancibilika ku-ethanol kanye ne-acetone.
Isicelo
I-Sodium iodide isetshenziswa kabanzi ekushintsheni kwe-halide (i-Finkelstein reaction), isibonelo ekuguqulweni kwe-alkyl chloride, i-allyl chloride kanye ne-arylmethyl chloride zibe yi-iodide yazo, okuyizinto ezandulela imikhiqizo yamakhemikhali neyemithi emihle. Zisetshenziselwa ukuthuthukisa ukusebenza kahle kokwakheka kwe-Wittig adducts kusuka kuma-chloride nama-bromide angasabeli kahle. Amalungiselelo afanele asetshenziswa njengesengezo sezakhamzimba. I-Sodium iodide isetshenziswa njengesandulela se-ejenti yokulawula ku-ab initio emulsion polymerization. I-Sodium iodide isetshenziswa ekunqumeni i-oxygen encibilikisiwe ngendlela ye-Winkler eguquliwe, ukwenziwa kwedayi ye-fluorescent coppersensor-1 (CS1) yokuthwebula amachibi ethusi acwebezelayo kumasampula ebhayoloji, kanye nokuqhekeka kwama-esters, ama-lactones, ama-carbamates nama-ethers kuhlanganiswe ne-chlorotrimethylsilane.
Ingasetshenziswa ekuhlolweni kwezicubu, ekuhlolweni kwe-urography ye-retrograde, ekuhlolweni kwe-cholangiography nge-T-tube kanye nase-fistula angiography yezinye izingxenye.
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: nquma indawo yomjovo kanye nomthamo ngokuya ngesimo sesifo.
I-sodium iodide yasetshenziswa njengengxenye yokulungiselela isixazululo se-hematoxylin stain sikaMayer.
Kungasetshenziswa kulezi zinqubo ezilandelayo:
I-precursor ekupholiseni kwe-butyl acrylate.
I-ejenti ye-chaotropic ekukhishweni kwe-DNA.
I-ejenti yokususa ukuvikela ekususweni kweqembu le-N-tert-butyloxycarbonyl kuma-amino acid.
I-reagent yokucima ukukhanya okuncibilikayo emanzini.
Ukupakisha Nokugcina Izinto
Ukupakisha: Isigubhu sekhadibhodi esifakwe isikhwama sepulasitiki, esingama-25KG/isigubhu.
Indawo Yokugcina: Ivaliwe futhi igcinwe ebumnyameni.
