Kushandiswa: Chinowedzera Kudya Kwemhuka kana Pharmacy
Sodium iodide chinhu chichena chinowanikwa kuburikidza nekuita pakati pesodium carbonate nehydroiodic acid uye kuwedzera kwemvura inobuda mumushonga. Kune anhydrous, dihydrate uye pentahydrate compound. Ndiyo chinhu chakakosha chekugadzira iodine, chekushandiswa mukurapa nekutora mifananidzo. Asidi yesodium iodide, nekuda kwekugadzirwa kwehydroiodic acid, inoratidza kugona kuderedza kusvibiswa kwemvura.
Zvivakwa zveChigadzirwa
Sodium iodide ihupfu hwekristaro chena kana kuti crystalline upfu husina ruvara. Hainhuwi uye inovava munyu. Inonwisa hunyoro kubva mumhepo; inoshanduka kuita brown zvishoma nezvishoma kana yabatwa nemhepo nekuda kweiyoodine yakabuda; density 3.67g/cm3; inonyunguduka pa660°C; inopwanyika pa1,304°C; vapor pressure 1 torr pa767°C uye 5 torr pa857°C; inonyunguduka mumvura, 178.7 g/100 mL pa20°C uye 294 g/100 mL pa70°C; inonyunguduka muethanol neacetone.
Kushandiswa
Sodium iodide inoshandiswa zvakanyanya pakuchinjana kwehalide (Finkelstein reaction), semuenzaniso mukushandura alkyl chloride, allyl chloride uye arylmethyl chloride kuita ma iodide avo, ayo ari precursors emishonga uye zvigadzirwa zvemakemikari zvakanaka. Anoshandiswa kusimbisa kushanda kweWittig adducts kubva kuma chloride ne bromides asingashande zvakanyanya. Kugadzirira kwakakodzera kunoshandiswa sekuwedzera kwezvinovaka muviri. Sodium iodide inoshandiswa senzira yekudzora mu ab initio emulsion polymerization. Sodium iodide inoshandiswa pakutsvaga oxygen yakanyungudutswa nenzira yakagadziridzwa yeWinkler, synthesis ye fluorescent dye coppersensor-1 (CS1) yekufungidzira madziva emhangura e labile muzviyero zve biological, uye kupatsanurwa kwe esters, lactones, carbamates uye ethers pamwe chete ne chlorotrimethylsilane.
Inogona kushandiswa pakuongorora masero etsinga, kuongorora urography, kuongorora cholangiography kuburikidza neT-tube uye kuongorora fistula angiography yezvimwe zvikamu zvemuviri.
Urography: 6.25% 100ml. Cystography: 6.25% 150ml. Retrograde pyelography: 12.5% 5~7ml. T-tube cholangiography: 12.5% 10~30ml. Fistula angiography: kuona nzvimbo yejekiseni uye dose zvichienderana nemamiriro echirwere.
Sodium iodide yakashandiswa mukugadzira mushonga weMayer's hematoxylin stain solution.
Inogona kushandiswa mune zvinotevera maitiro:
Chinotangira pakuumbwa kwebutyl acrylate.
Mushonga weChaotropic mukubvisa DNA.
Mushonga unobvisa dziviriro mukubvisa boka reN-tert-butyloxycarbonyl mumaamino acids.
Chinodzima fluorescence chinonyungudika mumvura.
Kurongedza & Kuchengeta
Kurongedza: Dhiramu remakadhibhodhi rakashongedzwa nebhegi repurasitiki, 25KG/dhiramu.
Kuchengetera: Yakavharwa uye inochengetwa murima.
