Zvenyama uye Chemical Properties
Chemical formula ndeye CuI. Huremu hwemamorekuru ndeye 190.45. White cubic crystal kana chena poda, ine chepfu. Density yehukama ndeye 5.62, nzvimbo yekunyunguduka i605 °C, nzvimbo yekubikira i1290 °C. Yakagadzikana kuchiedza nemhepo.Cuprous iodideinenge isinganyungudike mumvura uye ethanol, inonyungudika mu liquid ammonia, dilute hydrochloric acid, potassium iodide, potassium cyanide kana sodium thiosulfate solution, inogona c yakaora ne oncentrated sulfuric acid uye concentrated nitric acid.
Cuprous iodide inenge isinganyungudike mumvura (0.00042 g/L, 25 ° C) uye hainyungudike muacid, asi inogona kuramba ichidyidzana neiodide kuita linear [CuI2] ions, inonyungudika mupotassium iodide kana sodium iodide. Mukugadzirisa. Mushonga wakaitwa wakadirwa kuti upe cuprous iodide precipitate saka wakashandiswa kuchenesa cuprous iodide sample.
Iyo acidic solution yemhangura sulfate inowedzerwa yakawandisa potassium iodide kana pasi pekubvongodza, musanganiswa we potassium iodide uye sodium thiosulfate wakawedzerwa kudonha kune mhinduro yemhangura sulfate, kuwana kunaya kwekombi iodide. Pamusoro pekushandisa zvakajairika sema reagents, nezvimwewo, asi zvakare inogona kushandiswa sesimba-iodide yekupisa bepa conductive layer zvinhu, yekurapa sterilization, mechanic inotakura tembiricha mumiririri, asi zvakare inoshandiswa kuongorora trace mercury.
Toxicity: Kubatana kwenguva refu uye kudzokororwa nemuviri kunokuvadza, kunofanira kudzivirira kusangana kwakananga nemuviri. Kudya kukuvadza kukuru kumuviri.

1. Cuprous iodide inoshandiswa zvakanyanya secatalyst muorganic synthesis, resin modifier, artificial artificial ajenti ekunaya kwemvura, cathode ray chubhu chivharo, pamwe nekunobva ayodhine mumunyu une iodized. Muhupo hwe1,2-kana 1,3-diamine ligand, cuprous iodide inogona kukonzeresa kuita kwearyl bromide, vinyl bromide uye brominated heterocyclic compound ichishandura kune iodide inoenderana. Maitiro acho anowanzo mu dioxane solvent, uye sodium iodide inoshandiswa seiodide reagents. Iyo inonhuhwirira iodide general ine mhenyu kupfuura inoenderana chloride uye iodide, saka, iodide inogona kukonzeresa nhevedzano yemaitiro anobatanidzwa mukubatanidza halogenated hydrocarbon, semuenzaniso, Heck reaction, Stille reaction, Suzuki reaction uye Ullmann reaction. Mumazuva ano dichloro bis (triphenylphosphine) palladium (II), cuprous chloride uye diethylamine, 2-bromo-1-octen-3-ol ine 1-Nonyl acetylene coupling reaction kuti ibudise 7-sub-8-hexadecene-6-ol.
2. inoshandiswa sechinhu chinokonzera maitiro ehupenyu, cathode ray tube covering, inoshandiswawo sekuwedzera kwekudya kwemhuka, etc. iodide yemhangura uye mercuric iodide inogonawo kushandiswa pamwe chete sechiratidzo chekuyera kukwira kwekushisa kwe mechanical bearing.
3. sechinhu chinokonzeresa mukuita kwakawanda kunowanikwa muGrignard reagent, iyo iodide yemukombe inogonawo kunge iri muWiff yakaoma rearrangement reaction.
