Tungsten hexabromide ni iki?

Kandatungsten hexachloride(WCl6), tungsten hexabromideni na organic organique igizwe ninzibacyuho yicyuma tungsten nibintu bya halogene. Agaciro ka tungsten ni + 6, ifite imiterere myiza yumubiri nubumashini kandi ikoreshwa cyane mubuhanga bwimiti, catalizike nizindi nzego. Icyitonderwa: Bromine na chlorine nibice bya halogen, hamwe numubare wa atome wa 35 na 17.

Tungsten hexabromide ni bromide ya tungsten, ifu yijimye yijimye cyangwa ifu yijimye yijimye ikomeye ifite urumuri rwinshi, izina ryicyongereza Tungsten Hexafluoride, formula yimiti WBr6, uburemere bwa molekile 663.26, CAS nimero 13701-86-5, PubChem 14440251.

Kubireba imiterere, imiterere ya tungsten hexabromide ni sisitemu ya kristu ya mpandeshatu, hamwe na lattice ihagaze ya 639.4pm na c ya 1753pm. Igizwe na WBr6 octahedron. Atom ya tungsten iherereye hagati, ikikijwe na atome esheshatu za bromine. Buri atom ya bromine ihujwe na tungsten atom na covalent bond, ariko atome ya bromine ntabwo ihujwe nubundi buryo bwa chimique

Kubijyanye nimiterere yumubiri nubumashini, tungsten hexabromide igaragara nkifu yijimye yijimye cyangwa yijimye yijimye yijimye, ifite ubucucike bwa 6.9g / cm3 hamwe nugushonga kwa 232 ° C. Irashobora gushonga muri disulfide ya karubone, ether, karubone disulfide , ammonia na aside, bidashonga mumazi akonje, ariko byoroshye kubora muri acide tungstic mumazi ashyushye. Mugihe cyubushyuhe, byoroshye kubora muri tungsten pentabromide na bromine, hamwe no kugabanuka gukomeye, kandi bizagenda buhoro buhoro hamwe na ogisijeni yumye kugirango irekure bromine.

Ku bijyanye n’umusaruro, tungsten hexabromide irashobora gukorwa mugukora tungsten pentabromide hamwe na bromine mukirere gikingira nta ogisijeni; Mugukora hexacarbonyl tungsten hamwe na bromine; Byakozwe muguhuza tungsten hexachloride na boron tribromide; Gukora mu buryo butaziguye ibyuma bya tungsten cyangwa okiside ya tungsten hamwe na bromine ku bushyuhe bwinshi; Ubundi, gushonga tungsten tetrabromide na tungsten pentabromide birashobora gutegurwa mbere, hanyuma bigakorwa na bromine kugirango bibe.

Ku bijyanye n’imikoreshereze, tungsten hexabromide irashobora gukoreshwa mugutegura ibindi bikoresho bya tungsten, nka fluor tungsten, tungsten dibromide, nibindi; Catalizator, ibikoresho bya bromine, nibindi bikoreshwa muguhuza ibinyabuzima kama na chimie ya peteroli; Ikoreshwa mubakora inganda, amarangi, imiti, nibindi; Gukora urumuri rushya, amatara ya tungsten ya tromsten arasa cyane kandi ntoya mubunini, kandi arashobora gukoreshwa muma firime, gufotora, kumurika kuri stage, nibindi bice.
