Kodi tungsten hexabromide ndi chiyani?

MongaTungsten hexachloride(WCl6), tungsten hexabromideilinso pawiri wopangidwa ndi kusintha zitsulo tungsten ndi zinthu halogen. Valence ya tungsten ndi+6, yomwe ili ndi zinthu zabwino zakuthupi ndi zamankhwala ndipo imagwiritsidwa ntchito kwambiri mu engineering yamankhwala, catalysis ndi zina. Chidziwitso: Bromine ndi klorini ndizinthu zamagulu a halogen, okhala ndi nambala ya atomiki ya 35 ndi 17 motsatana.

Tungsten hexabromide ndi bromide ya tungsten, imvi yakuda kapena imvi yolimba yokhala ndi zitsulo zonyezimira, dzina lachingerezi Tungsten Hexafluoride, formula ya mankhwala WBr6, molekyulu yolemera 663.26, CAS nambala 13701-86-5, PubChem 14440251.

Pankhani ya kamangidwe, tungsten hexabromide kapangidwe ndi triangular kristalo dongosolo, ndi lattice constants a 639.4pm ndi c wa 1753pm. Zimapangidwa ndi WBr6 octahedron. Atomu ya tungsten ili pakati, yozunguliridwa ndi maatomu asanu ndi limodzi a bromine. Atomu iliyonse ya bromine imalumikizidwa ndi atomu ya tungsten ndi covalent bond, koma ma atomu a bromine samalumikizidwa mwachindunji ndi mgwirizano wamankhwala.

Pankhani ya thupi ndi mankhwala katundu, tungsten hexabromide amawoneka ngati mdima imvi ufa kapena kuwala imvi olimba, ndi kachulukidwe wa 6.9g/cm3 ndi malo osungunuka pafupifupi 232 ° C. Ndi sungunuka carbon disulfide, efa, carbon disulfide, ammonia ndi asidi, insoluble m'madzi ozizira, koma mosavuta decom acid. M'nyengo zotentha, zimawola mosavuta kukhala tungsten pentabromide ndi bromine, zochepetsera mphamvu, ndipo zimachita pang'onopang'ono ndi okosijeni wowuma kuti amasule bromine.

Pankhani ya kupanga, tungsten hexabromide imatha kupangidwa pochita tungsten pentabromide ndi bromine mumlengalenga woteteza popanda mpweya; Pochita hexacarbonyl tungsten ndi bromine; Amapangidwa pophatikiza tungsten hexachloride ndi boron tribromide; Mwachindunji anachita tungsten zitsulo kapena tungsten okusayidi ndi bromine pa kutentha; Kapenanso, sungunuka tungsten tetrabromide ndi tungsten pentabromide zitha kukonzedwa kaye, kenako ndikuchita ndi bromine kuti apange.

Pogwiritsa ntchito, tungsten hexabromide ingagwiritsidwe ntchito pokonzekera mankhwala ena a tungsten, monga tungsten fluoride, tungsten dibromide, ndi zina zotero; Catalysts, brominating wothandizira, etc. ntchito synthesis wa organic mankhwala ndi mafuta umagwirira; Amagwiritsidwa ntchito popanga opanga, utoto, mankhwala, ndi zina; Kupanga magetsi atsopano, nyali za tungsten za brominated ndizowala kwambiri komanso zazing'ono kukula kwake, ndipo zimatha kugwiritsidwa ntchito ngati mafilimu, kujambula, kuyatsa siteji, ndi zina.
