Wehewehe Huahana
Inoa huahana: Sodium Iodide
Helu CAS: 7681-82-5
MF: NaI
Papa Kūlana: Papa ʻAi, Papa ʻOihana, Papa Lāʻau Lapaʻau, Papa Reagent
Maʻemaʻe: 99% Min
ʻAno: Keʻokeʻo aniani a i ʻole ka pauka
Noi: Mea Hoʻohui Hānai Holoholona a i ʻole ka Hale Kūʻai Lāʻau Lapaʻau
He mea paʻa keʻokeʻo ka sodium iodide i loaʻa ma o ka hopena ma waena o ka sodium carbonate me ka waikawa hydroiodic a me ka hoʻoheheʻe hou ʻana o ka hopena. Aia nā hui anhydrous, dihydrate a me pentahydrate. ʻO ia ka mea maka no ka hana ʻana o ka iodine, no ka hoʻohana ʻana i ka lāʻau lapaʻau a me ke kiʻi ʻana. ʻO ka hopena waikawa o ka sodium iodide, ma muli o ka hana ʻana o ka waikawa hydroiodic, hōʻike i ka hiki ke hoʻemi.
Nā Waiwai Huahana
He kristal cubic kala ʻole ka sodium iodide a i ʻole ka pauka kristal keʻokeʻo. ʻAʻohe ona ʻala me ka ʻono paʻakai a ʻawaʻawa. Hoʻopili i ka makū mai ka lewa; lilo mālie i ʻeleʻele i ka wā e ʻike ʻia ai i ka lewa ma muli o ka iodine i ulu; density 3.67g/cm3; heheʻe ma 660°C; vaporizes ma 1,304°C; kaomi vaporize 1 torr ma 767°C a me 5 torr ma 857°C; hoʻoheheʻe loa i ka wai, 178.7 g/100 mL ma 20°C a me 294 g/100 mL ma 70°C; hoʻoheheʻe ʻia i loko o ka ethanol a me ka acetone.
Noi
Hoʻohana nui ʻia ka sodium iodide no ka hoʻololi halide (Finkelstein reaction), no ka laʻana i ka hoʻololi ʻana o kahi alkyl chloride, allyl chloride a me arylmethyl chloride i loko o kā lākou iodides, ʻo ia nā precursors no nā huahana lāʻau lapaʻau a me nā kemika maikaʻi. Hoʻohana ʻia lākou e hoʻomaikaʻi i ka pono o ka hoʻokumu ʻana o nā Wittig adducts mai nā chlorides a me nā bromides i emi iki ka reactive. Loaʻa nā hoʻomākaukau kūpono e hoʻohana ʻia ma ke ʻano he mea hoʻohui meaʻai. Hoʻohana ʻia ka sodium iodide ma ke ʻano he precursor i ka mea hoʻomalu i ka ab initio emulsion polymerization. Loaʻa ka hoʻohana ʻana o ka sodium iodide i ka hoʻoholo ʻana o ka oxygen i hoʻoheheʻe ʻia i ke ʻano Winkler i hoʻololi ʻia, synthesis o ka fluorescent dye coppersensor-1 (CS1) no ke kiʻi ʻana i nā loko keleawe labile i nā laʻana biological, a me ka cleavage o nā esters, lactones, carbamates a me nā ethers i hui pū ʻia me chlorotrimethylsilane.
Hiki ke hoʻohana ʻia no ka cystography, retrograde urography, cholangiography ma o T-tube a me ka fistula angiography o nā ʻāpana ʻē aʻe.
Urography: 6.25% 100ml. Cystography: 6.25% 150ml. Retrograde pyelography: 12.5% 5~7ml. T-tube cholangiography: 12.5% 10~30ml. Fistula angiography: e hoʻoholo i kahi i hoʻokomo ʻia a me ka nui e like me ke kūlana o ka maʻi.
Ua hoʻohana ʻia ka sodium iodide ma ke ʻano he ʻāpana i ka hoʻomākaukau ʻana o ka hopena hoʻoluʻu hematoxylin a Mayer.
Hiki ke hoʻohana ʻia i loko o nā kaʻina hana aʻe:
ʻO ka mea mua i ka polymerization o ka butyl acrylate.
ʻO ka mea Chaotropic i ka unuhi ʻana o ka DNA.
ʻO ka mea hoʻohemo pale i ka wehe ʻana o ka hui N-tert-butyloxycarbonyl i nā waikawa amino.
Mea hoʻoheheʻe fluorescence hoʻoheheʻe wai.
Hoʻopili a me ka mālama ʻana
Hoʻopili ʻia: Pahu pepa i hoʻopaʻa ʻia me ka ʻeke plastik, 25KG/pahu.
Ka mālama ʻana: Paʻa ʻia a mālama ʻia i ka pōʻeleʻele.
