Zakuthupi ndi Zamankhwala
Chemical formula ndi CuI. Kulemera kwa molekyulu ndi 190.45. White kiyubiki kristalo kapena woyera ufa, poizoni. Kachulukidwe wachibale ndi 5.62, malo osungunuka ndi 605 ° C, malo otentha ndi 1290 ° C. Wokhazikika pakuwala ndi mpweya.Cuprous ayodinipafupifupi insoluble m'madzi ndi Mowa, sungunuka mu madzi ammonia, kuchepetsa hydrochloric acid, potaziyamu ayodini, potaziyamu cyanide kapena sodium thiosulfate njira, akhoza c decomposed ndi oncentrated sulfuric acid ndi anaikira nitric asidi.
Iodide ya Cuprous imakhala pafupifupi yosasungunuka m'madzi (0.00042 g/L, 25 ° C) ndipo imasungunuka mu asidi, koma imatha kupitiriza kugwirizanitsa ndi ayodini kupanga ma ion [CuI2], omwe amasungunuka mu potassium iodide kapena sodium iodide. Mu yankho. Njira yotsatsirayo idachepetsedwa kuti ipatse mchere wa iodide wa cuprous ndipo idagwiritsidwa ntchito kuyeretsa sampuli ya ayodini ya cuprous.
Njira ya acidic ya mkuwa sulphate imawonjezeredwa ndi ayodini wa potaziyamu kapena kugwedezeka, njira yosakanikirana ya ayodini ya potaziyamu ndi sodium thiosulfate inawonjezeredwa dropwise ku njira ya mkuwa sulphate, kuti mupeze mpweya wa iodide wa cuprous. Kuwonjezera ambiri cholinga ntchito monga reagents, etc., komanso angagwiritsidwe ntchito ngati mphamvu-iodide matenthedwe pepala conductive wosanjikiza zakuthupi, mankhwala yolera yotseketsa, makina kubala kutentha wothandizila, komanso ntchito kusanthula kufufuza Mercury.
Poizoni: Kulumikizana kwa nthawi yayitali ndi thupi kumawononga, kuyenera kupewa kukhudzana mwachindunji ndi thupi. Kudya kumavulaza kwambiri thupi.

1. Cuprous iodide amagwiritsidwa ntchito kwambiri monga chothandizira mu organic synthesis, resin modifier, mvula yakupanga, chivundikiro cha chubu cha cathode ray, komanso magwero a ayodini mumchere wokhala ndi ayodini. Pamaso pa 1,2-kapena 1,3-diamine ligand, cuprous iodide imatha kuyambitsa zomwe aryl bromide, vinilu bromide ndi brominated heterocyclic pawiri kutembenukira ku iodide yofananira. Zomwe zimachitika nthawi zambiri zimakhala mu zosungunulira za dioxane, ndipo sodium iodide imagwiritsidwa ntchito ngati iodide reagents. Mafuta onunkhira a iodide amakhala osangalatsa kuposa ma chloride ndi ayodini, chifukwa chake, ayodini amatha kuyambitsa zinthu zingapo zomwe zimachitika pophatikiza halogenated hydrocarbon, mwachitsanzo, Heck reaction, Stille reaction, Suzuki reaction and Ullmann reaction. Pakalipano dichloro bis (triphenylphosphine) palladium (II), cuprous chloride ndi diethylamine, 2-bromo-1-octen-3-ol ndi 1-Nonyl acetylene coupling reaction kuti apange 7-sub-8-hexadecene-6-ol.
2. ntchito monga chothandizira organic zimachitikira, cathode ray chubu chophimba, komanso ntchito monga nyama zowonjezera zakudya, etc. ayodini zamkuwa ndi mercuric ayodini angagwiritsidwenso ntchito limodzi monga chizindikiro kuyeza kukwera kutentha kwa makina kubala.
3. monga chothandizira mu zochita zambiri nawo Grignard reagent, cuprous ayodini angakhalenso youma Wiff rearrangement anachita.
