CAS: 1317-40-4|COPPER(II) SULFIDE

Taw qhia thiab daim ntawv thov ntawm CAS: CAS: 1317-40-4|COPPER(II) SULFIDE

Indigo xiav, dub monoclinic los yog hexagonal siv lead ua system, nrog nws cov xim hlau luster, tshuaj formula CuS, tooj liab sulfide muaj nyob rau hauv cov xwm nyob rau hauv daim ntawv ntawm indigo tooj liab sulfide. Nrog ib tug txheeb ze ceev ntawm 4.6, nws yog ruaj khov nyob rau hauv qhuav huab cua. Nws yog maj mam oxidized rau hauv tooj liab sulfate nyob rau hauv cov huab cua ntub thiab decomposes thaum rhuab mus rau 220 degree . Yuav luag insoluble nyob rau hauv dej los yog ethanol, nrog ib tug me me solubility khoom (8.0 × 10-37), soluble nyob rau hauv kub dilute nitric acid, kub concentrated hydrochloric acid los yog concentrated sulfuric acid los tsim divalent tooj liab ntsev ntawm cov kua qaub; yooj yim soluble hauv kub potassium cyanide Hauv KCN los yog sodium cyanide CaCN tov, tooj liab tetracyano(Ⅰ) complex ion [Cu(CN)4]3-(poov tshuaj tetracyanocopper(Ⅱ)ate) yog tsim. Hauv kev tsim tshuaj thiab tshuaj chemistry, cov insolubility ntawm tooj liab sulfide tuaj yeem siv los cais cov hlau ions hauv cov tshuaj. Piv txwv li, nyob rau hauv ib tug sib tov tov ntawm Ni2+-Cu2+, Zn2+-Cu2+, cov tshuaj yog thawj zaug hloov mus rau me ntsis acidic, thiab ces hydrogen sulfide gas yog qhia. . , dub CuS precipitate yuav raug tsim, thiab Cu2+ hauv cov tshuaj yuav raug tshem tawm kom ua tiav lub hom phiaj ntawm kev sib cais. Nyob rau hauv lub chaw soj nstuam, hydrogen sulfide yog nkag mus rau hauv me ntsis acidic tooj liab sulfate tov los yog ammonium sulfide yog ntxiv rau cov tooj liab sulfate tov, thiab cov precipitated precipitate yog lim, ntxuav, thiab qhuav kom tau cov khoom tiav tooj liab sulfide. Nws feem ntau yog siv los kho cov tooj liab, npaj cov khoom siv tooj liab, thiab npaj cov catalysts sib xyaw, aniline dub dye developers, thiab nkoj hauv qab tiv thaiv txheej.
