Liketungsten hexachloride(WCl6), tungsten hexabromideHe pūhui anorganic kekahi i haku ʻia me ka tungsten metala hoʻololi a me nā mea halogen.ʻO ka valence o ka tungsten he + 6, nona nā waiwai kino a me nā kemika maikaʻi a hoʻohana nui ʻia i ka ʻenekinia kemika, catalysis a me nā māla ʻē aʻe.'Ōlelo Aʻo: No nā mea hui halogen ka bromine a me ka chlorine, me ka helu atomika o 35 a me 17.
ʻO Tungsten hexabromide he bromide o ka tungsten, he pauka hina ʻeleʻele a i ʻole kahi paʻa hina hina me ka ʻulaʻula metala, inoa Pelekane ʻo Tungsten Hexafluoride, kumu kemika WBr6, paona molekala 663.26, helu CAS 13701-86-5, PubChem 14440251.
Ma nā ʻōlelo o ka hoʻolālā, ʻo ka tungsten hexabromide structure he triangular crystal system, me nā lattice constants a o 639.4pm a me c o 1753pm.Ua haku ʻia ʻo WBr6 octahedron.Aia ka ʻātoma tungsten ma ke kikowaena, i hoʻopuni ʻia e nā ʻātoma bromine ʻeono.Hoʻopili ʻia kēlā me kēia bromine atom i ka tungsten atom e ka covalent bond, akā ʻaʻole pili pono nā bromine atom me kekahi i kekahi e ka paʻa kemika.
Ma keʻano o ke kino a me nā waiwai kemika, ʻike ʻia ka tungsten hexabromide e like me ka pauka hina hina a i ʻole ka paʻa hina hina, me ka density o 6.9g / cm3 a me kahi helu hoʻoheheʻe ma kahi o 232 ° C. Hiki ke hoʻoheheʻe ʻia i ka carbon disulfide, ether, carbon disulfide. , amonia a me ka waika, hiki ole ke hooheheeia i ka wai anuanu, aka, hiki ke hoopau i ka waika tungstic i ka wai wela.Ma lalo o nā kūlana hoʻomehana, hiki ke hoʻoheheʻe ʻia i loko o ka tungsten pentabromide a me ka bromine, me ka hoʻohaʻahaʻa ikaika ʻana, a e hana mālie me ka oxygen maloʻo e hoʻokuʻu i ka bromine.
Ma keʻano o ka hanaʻana, hiki ke hanaʻia ka tungsten hexabromide ma ka hanaʻana i ka tungsten pentabromide me ka bromine i loko o kahi ea pale me ka oxygenʻole;Ma ka hana ʻana i ka tungsten hexacarbonyl me ka bromine;Hoʻokumu ʻia e ka hui ʻana o ka tungsten hexachloride me ka boron tribromide;Hoʻopili pololei i ka metala tungsten a i ʻole tungsten oxide me ka bromine i ka wela kiʻekiʻe;ʻO kahi ʻē aʻe, hiki ke hoʻomākaukau mua ʻia ka tungsten tetrabromide a me ka tungsten pentabromide, a laila hana ʻia me ka bromine e hana ai.
Ma keʻano o ka hoʻohanaʻana, hiki ke hoʻohanaʻia ka tungsten hexabromide e hoʻomākaukau i nā pūhui tungsten'ē aʻe, e like me ka fluoride tungsten, tungsten dibromide, etc;Hoʻohana ʻia nā Catalysts, brominating agents, a me nā mea ʻē aʻe i ka synthesis o nā pūhui organik a me ka ʻaila kemika;Hoʻohana ʻia no ka hana ʻana i nā mea hoʻomohala, nā mea pena, nā lāʻau lapaʻau, etc.ʻO ka hana ʻana i nā kumu kukui hou, nā kukui tungsten brominated he mālamalama a liʻiliʻi i ka nui, a hiki ke hoʻohana ʻia no nā kiʻiʻoniʻoni, kiʻi kiʻi, kukui kahua, a me nā mea ʻē aʻe.
