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 iphendule nge-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.
