Thandai-tungsten hexachloride(WCl6), i-tungsten hexabromidefuthi iyinhlanganisela ye-inorganic eyakhiwe nge-transition metal tungsten kanye nezakhi ze-halogen.I-valence ye-tungsten ingu+6, enezakhiwo ezinhle zomzimba namakhemikhali futhi isetshenziswa kakhulu kubunjiniyela bamakhemikhali, i-catalysis neminye imikhakha.Qaphela: I-Bromine ne-chlorine kuyingxenye yeqembu le-halogen, enenombolo ye-athomu engu-35 kanye ne-17 ngokulandelanayo.
I-Tungsten hexabromide iyi-bromide ye-tungsten, impushana emnyama emnyama noma okuqinile okumpunga okukhanyayo okukhazimulayo kwensimbi, igama lesiNgisi elithi Tungsten Hexafluoride, ifomula yamakhemikhali i-WBr6, isisindo samangqamuzana 663.26, inombolo ye-CAS 13701-86-5, PubChem 14440251.
Ngokwesakhiwo, isakhiwo se-tungsten hexabromide siwuhlelo lwekristalu elingunxantathu, olunama-lattice constants angu-639.4pm kanye no-c ka-1753pm.Yakhiwe nge-WBr6 octahedron.I-athomu ye-tungsten iphakathi nendawo, izungezwe ama-athomu e-bromine ayisithupha.I-athomu ngayinye ye-bromine ixhunywe ku-athomu ye-tungsten nge-covalent bond, kodwa ama-athomu e-bromine awaxhumene namanye ngokuqondile ngesibopho samakhemikhali.
Mayelana nezakhiwo zomzimba nezamakhemikhali, i-tungsten hexabromide ibonakala iyimpushana emnyama empunga noma okuqinile okumpunga okukhanyayo, nokuminyana okungu-6.9g/cm3 kanye nephuzu elincibilikayo elingama-232 ° C. Incibilika ku-carbon disulfide, ether, carbon disulfide , i-ammonia ne-asidi, engancibiliki emanzini abandayo, kodwa ibola kalula ibe i-tungstic acid emanzini ashisayo.Ngaphansi kwezimo zokushisisa, ibola kalula ibe yi-tungsten pentabromide ne-bromine, enokuncipha okuqinile, futhi izosabela kancane ngomoya owomile ukuze ikhulule i-bromine.
Mayelana nokukhiqizwa, i-tungsten hexabromide ingakhiwa ngokuphendula i-tungsten pentabromide ne-bromine endaweni yokuzivikela ngaphandle kwe-oxygen;Ngokusabela i-hexacarbonyl tungsten ne-bromine;Yakhiwe ngokuhlanganisa i-tungsten hexachloride ne-boron tribromide;Ukusabela ngokuqondile kwe-tungsten metal noma i-tungsten oxide ene-bromine ekushiseni okuphezulu;Kungenjalo, i-tungsten tetrabromide encibilikayo ne-tungsten pentabromide ingalungiselelwa kuqala, bese isabela nge-bromine ukuze zakhe.
Mayelana nokusetshenziswa, i-tungsten hexabromide ingasetshenziswa ukulungisa ezinye izinhlanganisela ze-tungsten, njenge-tungsten fluoride, i-tungsten dibromide, njll;Ama-Catalysts, ama-brominating agents, njll. asetshenziswa ekuhlanganiseni ama-organic compounds kanye ne-petroleum chemistry;Isetshenziselwa ukukhiqiza onjiniyela, odayi, imithi, njll;Ukukhiqiza imithombo yokukhanya emisha, amalambu e-tungsten e-brominated akhanya kakhulu futhi mancane ngosayizi, futhi angasetshenziselwa amamuvi, ukuthwebula izithombe, ukukhanyisa kwesiteji, nezinye izici.
