Njengotungsten hexachloride(WCl6), tungsten hexabromideikwayikhompawundi ye-inorganic eyenziwe nge-transition metal tungsten kunye ne-halogen element.I-valence ye-tungsten yi+6, eneempawu ezintle zomzimba kunye neekhemikhali kwaye isetyenziswa ngokubanzi kubunjineli bemichiza, i-catalysis kunye nezinye iindawo.Qaphela: I-Bromine kunye neklorini zizinto zeqela le-halogen, kunye nenani le-athomu lama-35 kunye ne-17 ngokulandelelanayo.
I-Tungsten hexabromide yi-bromide ye-tungsten, i-powder grey emnyama okanye i-gray grey eqinile ene-metallic luster, igama lesiNgesi i-Tungsten Hexafluoride, i-chemical formula WBr6, i-molecular weight 663.26, inombolo ye-CAS 13701-86-5, i-PubChem 14440251.
Ngokwesakhiwo, isakhiwo se-tungsten hexabromide yinkqubo ye-crystal engunxantathu, kunye ne-lattice constants ye-639.4pm kunye ne-c ye-1753pm.Yenziwe nge-WBr6 octahedron.Iathom yetungsten isembindini, ijikelezwe ziiathom zebromine ezintandathu.Iathom nganye yebromine iqhagamshelwe kwiathom yetungsten ngebhondi edibeneyo, kodwa iiathom zebromine azidityaniswanga enye kwenye ngokuthe ngqo ngeqhina lekhemikhali.
Ngokubhekiselele kwizinto eziphathekayo kunye neekhemikhali, i-tungsten i-hexabromide ibonakala njengomgubo obumnyama obumnyama okanye ukukhanya okuluhlaza okuqinileyo, kunye nobuninzi be-6.9g / cm3 kunye nendawo yokunyibilika malunga ne-232 ° C. I-soluble kwi-carbon disulfide, i-ether, i-carbon disulfide , i-ammonia kunye ne-asidi, enganyibilikiyo emanzini abandayo, kodwa ibola ngokulula ibe yi-tungstic acid emanzini ashushu.Ngaphantsi kweemeko zokufudumeza, ukubola ngokulula kwi-tungsten pentabromide kunye ne-bromine, kunye ne-reducibility enamandla, kwaye iya kusabela ngokukhawuleza nge-oksijini eyomileyo ukukhulula i-bromine.
Ngokwemveliso, i-tungsten hexabromide inokubunjwa ngokuphendula i-tungsten pentabromide kunye ne-bromine kwindawo ekhuselayo ngaphandle kwe-oksijini;Ngokusabela i-hexacarbonyl tungsten kunye nebromine;Yenziwe ngokudibanisa i-tungsten hexachloride kunye ne-boron tribromide;Ukuphendula ngokuthe ngqo i-tungsten metal okanye i-tungsten oxide kunye ne-bromine kwiqondo lokushisa eliphezulu;Ngenye indlela, i-tungsten tetrabromide enyibilikayo kunye ne-tungsten pentabromide inokulungiswa kuqala, kwaye emva koko ixutywe ne-bromine ukuze zenze.
Ngokwemigaqo yokusetyenziswa, i-tungsten hexabromide ingasetyenziselwa ukulungisa ezinye iikhompawundi ze-tungsten, ezifana ne-tungsten fluoride, i-tungsten dibromide, njl.I-Catalysts, i-brominating agents, njl.ezisetyenziswa kwi-synthesis ye-organic compounds kunye ne-petroleum chemistry;Isetyenziselwa ukwenza abaphuhlisi, iidayi, amayeza, njl.Ukuvelisa imithombo yokukhanya emitsha, izibane ze-tungsten ezikhanyayo zikhanya kakhulu kwaye zincinci ngobukhulu, kwaye zingasetyenziselwa iimuvi, ukufota, ukukhanya kweqonga, kunye neminye imiba.
