Cov Khoom Siv Lub Cev thiab Tshuaj
Cov mis tshuaj yog CuI. Qhov hnyav molecular yog 190.45. Dawb cubic siv lead ua los yog hmoov dawb, lom. Qhov ceev ntawm qhov sib piv yog 5.62, melting point yog 605 ° C, boiling point yog 1290 ° C. Ruaj khov rau lub teeb thiab huab cua.Cov tshuaj iodide cuprousyuav luag tsis yaj hauv dej thiab ethanol, yaj hauv kua ammonia, dilute hydrochloric acid, potassium iodide, potassium cyanide lossis sodium thiosulfate kua, tuaj yeem decomposed los ntawm concentrated sulfuric acid thiab concentrated nitric acid.
Cuprous iodide yuav luag tsis yaj hauv dej (0.00042 g/L, 25 ° C) thiab tsis yaj hauv kua qaub, tab sis tuaj yeem txuas ntxiv sib koom tes nrog iodide los tsim cov linear [CuI2] ions, uas yaj hauv potassium iodide lossis sodium iodide. Hauv cov tshuaj. Cov tshuaj tau raug diluted kom muab cov cuprous iodide precipitate thiab yog li ntawd tau siv los ntxuav cov qauv cuprous iodide.
Cov kua qaub ntawm tooj liab sulfate yog ntxiv cov potassium iodide ntau dhau los yog do, cov kua sib xyaw ntawm potassium iodide thiab sodium thiosulfate tau ntxiv rau hauv cov kua tooj liab sulfate, kom tau cov cuprous iodide nag. Ntxiv rau kev siv dav dav ua cov tshuaj reagents, thiab lwm yam, tab sis kuj siv tau ua cov ntaub ntawv thermal fais fab-iodide, kev kho mob kom tsis muaj menyuam, tus neeg sawv cev kub, tab sis kuj siv rau kev tshuaj xyuas cov mercury me me.
Kev Lom: Kev sib cuag ntev thiab rov ua dua nrog lub cev yog qhov txaus ntshai, yuav tsum tsis txhob sib cuag ncaj qha nrog lub cev. Kev noj yog qhov txaus ntshai heev rau lub cev.

1. Cuprous iodide yog siv dav ua catalyst hauv cov organic synthesis, resin modifier, artificial rainfall agents, cathode ray tube cover, nrog rau cov chaw ntawm iodine hauv iodized ntsev. Nyob rau hauv lub xub ntiag ntawm 1,2-lossis 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 iodide sib xws. Cov tshuaj tiv thaiv feem ntau yog nyob rau hauv dioxane solvent, thiab sodium iodide yog siv ua iodide reagents. Aromatic iodide feem ntau muaj zog dua li cov chloride thiab iodide sib xws, yog li ntawd, iodide tuaj yeem catalyze ntau yam tshuaj tiv thaiv uas koom nrog kev sib txuas cov halogenated hydrocarbon, piv txwv li, Heck tshuaj tiv thaiv, Stille tshuaj tiv thaiv, Suzuki tshuaj tiv thaiv thiab Ullmann tshuaj tiv thaiv. Nyob rau hauv tam sim no ntawm dichloro bis (triphenylphosphine) palladium (II), cuprous chloride thiab diethylamine, 2-bromo-1-octen-3-ol nrog 1-Nonyl acetylene coupling reaction los tsim 7-sub-8-hexadecene-6-ol.
2. siv ua ib qho catalyst rau cov tshuaj tiv thaiv organic, cathode ray tube npog, kuj siv ua cov khoom noj tsiaj, thiab lwm yam. tooj liab iodide thiab mercuric iodide kuj tseem siv tau ua ke ua qhov ntsuas ntawm kev ntsuas qhov kub ntawm cov khoom siv kho tshuab.
3. ua ib qho catalyst hauv ntau cov tshuaj tiv thaiv uas koom nrog hauv Grignard reagent, cov cuprous iodide kuj tseem tuaj yeem ua rau cov tshuaj tiv thaiv Wiff rearrangement qhuav.
1. Ntim: Feem ntau 25kgs ib lub thawv ntawv.
2.MOQ: 1kg
3. Lub sijhawm xa khoom: Feem ntau 3-7 hnub tom qab them nyiaj.
