Physical thiab Chemical Properties
Cov tshuaj formula yog CuI. Qhov hnyav molecular yog 190.45. Dawb cubic siv lead ua los yog hmoov dawb, tshuaj lom. Tus txheeb ze ceev yog 5.62, melting point yog 605 ° C, boiling point yog 1290 ° C. Stable rau lub teeb thiab cua.Khob iodideNws yuav luag insoluble hauv dej thiab ethanol, soluble hauv kua ammonia, dilute hydrochloric acid, potassium iodide, potassium cyanide los yog sodium thiosulfate tov, tuaj yeem decomposed los ntawm oncentrated sulfuric acid thiab concentrated nitric acid.
Cuprous iodide yuav luag insoluble nyob rau hauv dej (0.00042 g / L, 25 ° C) thiab yog insoluble nyob rau hauv acid, tab sis muaj peev xwm txuas ntxiv mus koom tes nrog iodide los tsim linear [CuI2] ions, uas yog soluble nyob rau hauv poov tshuaj iodide los yog sodium iodide. Hauv kev daws teeb meem. Cov kev daws teeb meem tau diluted kom muab lub khob khob iodide precipitate thiab yog li ntawd tau siv los ntxuav cov qauv cuprous iodide.
Cov kua qaub ntawm tooj liab sulfate yog ntxiv ntau tshaj poov tshuaj iodide los yog nyob rau hauv stirring, ib tug tov ntawm poov tshuaj iodide thiab sodium thiosulfate yog ntxiv dropwise rau ib tug daws ntawm tooj liab sulfate, kom tau los nag ntawm cuprous iodide. Ntxiv rau kev siv lub hom phiaj dav dav raws li cov tshuaj reagents, thiab lwm yam, tab sis kuj tuaj yeem siv los ua hluav taws xob-iodide thermal ntawv txheej txheej khoom, kev kho mob kom tsis muaj menyuam, tus neeg saib xyuas qhov kub thiab txias, tab sis kuj siv rau kev tsom xam cov kab mercury.
Toxicity: Ntev ntev thiab rov sib cuag nrog lub cev yog qhov teeb meem, yuav tsum tsis txhob sib cuag nrog lub cev. Kev noj tshuaj yog qhov ua rau lub cev hnyav heev.

1. Cuprous iodide yog dav siv los ua catalyst nyob rau hauv cov organic synthesis, resin modifier, dag dej nag cov neeg sawv cev, cathode ray tube npog, raws li zoo raws li qhov chaw ntawm iodine nyob rau hauv iodized ntsev. Nyob rau hauv lub xub ntiag ntawm 1,2-los yog 1,3-diamine ligand, cuprous iodide tuaj yeem catalyze cov tshuaj tiv thaiv ntawm aryl bromide, vinyl bromide thiab brominated heterocyclic compound hloov mus rau cov khoom siv iodide. Cov tshuaj tiv thaiv feem ntau yog dioxane hnyav, thiab sodium iodide yog siv los ua iodide reagents. Aromatic iodide feem ntau muaj sia nyob ntau dua li cov tshuaj chloride thiab iodide sib xws, yog li ntawd, iodide tuaj yeem ua rau muaj kev cuam tshuam los ntawm kev sib txuas ntawm halogenated hydrocarbon, piv txwv li, Heck cov tshuaj tiv thaiv, Stille cov tshuaj tiv thaiv, Suzuki cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv Ullmann. Tam sim no ntawm dichloro bis (triphenylphosphine) palladium (II), cuprous chloride thiab diethylamine, 2-bromo-1-octen-3-ol nrog 1-Nonyl acetylene coupling cov tshuaj tiv thaiv los tsim 7-sub-8-hexadecene-6-ol.
2. siv los ua catalyst rau cov tshuaj tiv thaiv organic, cathode ray tube npog, kuj siv los ua tsiaj pub additives, thiab lwm yam. tooj liab iodide thiab mercuric iodide kuj tseem siv ua ke raws li qhov taw qhia ntawm kev ntsuas qhov ntsuas kub ntawm cov neeg kho tshuab bearing.
3. raws li ib tug catalyst nyob rau hauv ntau yam kev cuam tshuam nrog rau cov Grignard reagent, lub cuprous iodide kuj yuav nyob rau hauv qhuav Wiff rearrangement cov tshuaj tiv thaiv.
