Zoo litungsten hexachloride(WCl6), tungsten hexabromide hmoovNws kuj yog ib qho inorganic compound tsim los ntawm kev hloov pauv hlau tungsten thiab halogen ntsiab. Lub valence ntawm tungsten yog +6, uas muaj lub cev zoo thiab tshuaj lom neeg thiab yog dav siv nyob rau hauv chemical engineering, catalysis thiab lwm yam teb. Nco tseg: Bromine thiab chlorine muaj nyob rau hauv pawg halogen cov ntsiab lus, nrog rau atomic tooj ntawm 35 thiab 17 feem.
Tungsten hexabromide yog ib tug bromide ntawm tungsten, ib tug maub grey hmoov los yog lub teeb grey khoom nrog metallic luster, lus Askiv lub npe Tungsten Hexafluoride, tshuaj formula WBr6, molecular hnyav 663.26, CAS naj npawb 13701-86-5, PubChem 14440251.
Nyob rau hauv cov nqe lus ntawm cov qauv, cov qauv tungsten hexabromide yog ib daim duab peb sab siv lead ua, nrog lattice tas li ntawm 639.4 teev tsaus ntuj thiab c ntawm 1753 teev tsaus ntuj. Nws yog tsim los ntawm WBr6 octahedron. Lub tungsten atom nyob rau hauv qhov chaw, surrounded los ntawm rau bromine atoms. Txhua lub bromine atom txuas nrog tungsten atom los ntawm covalent daim ntawv cog lus, tab sis cov bromine atoms tsis txuas nrog ib leeg ncaj qha los ntawm cov tshuaj lom neeg.
Nyob rau hauv cov nqe lus ntawm lub cev thiab tshuaj zog, tungsten hexabromide tshwm raws li ib tug maub grey hmoov los yog lub teeb grey khoom, nrog ib tug ceev ntawm 6.9g / cm3 thiab ib tug melting point ntawm txog 232 ° C. Nws yog soluble nyob rau hauv carbon disulfide, ether, carbon disulfide. , ammonia thiab acid, insoluble hauv dej txias, tab sis yooj yim decomposes rau hauv tungstic acid hauv dej kub. Nyob rau hauv cov cua kub, nws yooj yim decomposes rau hauv tungsten pentabromide thiab bromine, muaj zog reducibility, thiab yuav maj mam reacts nrog qhuav oxygen kom tso bromine.
Nyob rau hauv cov nqe lus ntawm ntau lawm, tungsten hexabromide tuaj yeem tsim los ntawm reacting tungsten pentabromide nrog bromine hauv qhov chaw tiv thaiv tsis muaj oxygen; Los ntawm reacting hexacarbonyl tungsten nrog bromine; Tsim los ntawm kev sib txuas ntawm tungsten hexachloride nrog boron tribromide; Ncaj nraim reacting tungsten hlau los yog tungsten oxide nrog bromine ntawm qhov kub thiab txias; Xwb, soluble tungsten tetrabromide thiab tungsten pentabromide tuaj yeem npaj ua ntej, thiab tom qab ntawd rov ua dua nrog bromine los tsim lawv.
Hais txog kev siv, tungsten hexabromide tuaj yeem siv los npaj lwm cov tungsten compounds, xws li tungsten fluoride, tungsten dibromide, thiab lwm yam; Catalysts, brominating agents, thiab lwm yam. siv nyob rau hauv lub synthesis ntawm cov organic tebchaw thiab roj av chemistry; Siv rau cov neeg tsim khoom tsim, dyes, tshuaj, thiab lwm yam; Kev tsim cov teeb pom kev tshiab, brominated tungsten teeb yog qhov kaj thiab me me, thiab tuaj yeem siv rau kev ua yeeb yaj kiab, yees duab, theem teeb pom kev zoo, thiab lwm yam.
