Daim Ntawv Thov: Cov Khoom Noj Tsiaj Txhu lossis Tshuaj
Sodium iodide yog ib yam khoom dawb uas tau los ntawm kev sib xyaw ntawm sodium carbonate nrog hydroiodic acid thiab ntxiv cov kua dej. Muaj cov anhydrous, dihydrate thiab pentahydrate compound. Nws yog cov khoom siv raw rau kev tsim cov iodine, rau kev siv hauv kev kho mob thiab kev thaij duab. Cov kua qaub ntawm sodium iodide, vim yog lub cim ntawm hydroiodic acid, qhia txog kev muaj peev xwm txo qis.
Cov Khoom Siv
Sodium iodide yog ib hom siv lead ua cubic uas tsis muaj xim los yog hmoov dawb crystalline. Nws tsis muaj ntxhiab tsw qab nrog saj ntsev iab. Nws nqus tau cov dej noo ntawm huab cua; maj mam hloov xim av thaum raug huab cua vim yog iodine hloov zuj zus; qhov ceev yog 3.67g/cm3; yaj ntawm 660°C; vaporizes ntawm 1,304°C; vapor pressure 1 torr ntawm 767°C thiab 5 torr ntawm 857°C; yaj tau zoo heev hauv dej, 178.7 g/100 mL ntawm 20°C thiab 294 g/100 mL ntawm 70°C; yaj tau hauv ethanol thiab acetone.
Daim Ntawv Thov
Sodium iodide siv dav rau kev pauv halide (Finkelstein reaction), piv txwv li hauv kev hloov pauv ntawm alkyl chloride, allyl chloride thiab arylmethyl chloride mus rau hauv lawv cov iodides, uas yog cov khoom ua ntej rau cov tshuaj thiab cov khoom siv tshuaj zoo. Lawv siv los txhim kho qhov ua tau zoo ntawm kev tsim Wittig adducts los ntawm cov chlorides thiab bromides uas tsis tshua muaj zog. Cov kev npaj tsim nyog pom siv ua cov khoom noj khoom haus ntxiv. Sodium iodide siv ua cov khoom ua ntej rau tus neeg sawv cev tswj hwm hauv ab initio emulsion polymerization. Sodium iodide pom siv hauv kev txiav txim siab ntawm cov pa oxygen yaj hauv txoj kev hloov kho Winkler, kev tsim cov xim fluorescent dye coppersensor-1 (CS1) rau kev thaij duab cov pas dej tooj liab hauv cov qauv tshuaj lom neeg, thiab kev sib cais ntawm esters, lactones, carbamates thiab ethers ua ke nrog chlorotrimethylsilane.
Nws siv tau rau cystography, retrograde urography, cholangiography ntawm T-tube thiab fistula angiography ntawm lwm qhov.
Kev kuaj zis: 6.25% 100ml. Kev kuaj zis Cystography: 6.25% 150ml. Kev kuaj zis Retrograde: 12.5% 5~7ml. Kev kuaj cholangiography T-tube: 12.5% 10~30ml. Kev kuaj angiography fistula: txiav txim siab qhov chaw txhaj tshuaj thiab koob tshuaj raws li qhov mob.
Sodium iodide tau siv los ua ib feem hauv kev npaj Mayer's hematoxylin stain solution.
Nws siv tau rau hauv cov txheej txheem hauv qab no:
Cov khoom ua ntej hauv kev polymerization ntawm butyl acrylate.
Tus neeg sawv cev chaotropic hauv kev rho tawm DNA.
Tus neeg sawv cev tiv thaiv kev puas tsuaj hauv kev tshem tawm N-tert-butyloxycarbonyl pawg hauv cov amino acids.
Cov tshuaj reagent fluorescence quenching uas yaj tau hauv dej.
Ntim Khoom & Khaws Cia
