Hydride sodium. The guryaha iyo sharaxaad ee codsiga.

Ka hor inta aadan xalliso wixii sifooyinka hydride sodium, waxaa lagama maarmaan ah in la ogaado waxa uu yahay, halkaasoo loo adeegsaday iyo sida ay muhiimka u tahay. Su'aalahan in laga jawaabo aan qof kasta, si kastaba ha ahaatee, Jaahil ah macluumaadka sida uusan ku hadlin ma ah oo ku saabsan tarayn ee walaxda doonaa. Just sida xarumaha kale ee sodium, waxaa si weyn loo codsatay in industry.

Isku day inaad si ay u fahmaan arrimaha, oo ina keena aynu ku bilaw u qeexida iyo sharaxaad ee xarunta. Sayidka, sodium hydride - walax adag imanba isagoo formula NaH ah, budada hygroscopic grayish-cad ama caddaan. Waxa diyaariyey reaction ee ay u qaboobo oo dareere ah inert gaaska hydrogen iyo sodium macdan ah. Codso walax this for karboksidirovaniya, alkylation iyo acylation of daciif C-H-acid. The dhexgalka ee xarunta this biyo siinayaa hydroxide xal (hydroxide sodium, sodium hydroxide).

Sidaas, hadda si toos ah on sifooyinka hydride sodium. First of dhan, waa dhexdhexaad ah marka la eego biraha, kaas oo ku hoos jira xaalad caadiga ah waa u nugul daxalka. Marka la isticmaalayo walax this, inkastoo dhammaan noocyada xagashada, roughness iyo cilladaha ee oogada sare ee biraha, waxaa isku qaybiyeen oo ilaaliya dusha sare. hydride sodium, taas oo loo isticmaalayo in macdan saliid ama Consort kale ee foomka of ganaax. Waayo adag waa in hore loo kululayn jiray ilaa 100 digrii. hydride Sodium dhalaalayaa at 800 degrees Celsius, laakiin tani waxay dhacdaa keliya cadaadis ku hoos.

Qoraalkan, iyo sidoo kale hydride calcium, titanium iyo zirconium, si wanaagsan u saameyneysaa vulcanizates caag. In iyaga waxaa isla markiiba waxaa maamula ka hor inta nidaamka vulcanization qaab dispersions in petrolatum, gaaska la shito ama saliid macdanta. hydride Sodium in qaar ka mid ah guryaha jireed la mid ah chloride sodium, laakiin ay wax soo saarka waa wax yar ka sii culus oo ka qaalisan. Sidaa darteed, baaxadda sifooyin u gaar ah sodium hydride ay sabab u tahay taas oo uu leeyahay oo kaliya xarunta sodium. Laakiin hababka kiimikada qaada oo meel qayb ka mid ah chloride sodium iyo hydride sodium, si weyn u kala duwan yihiin.

hydride Sodium si firfircoon loo isticmaalaa in lagu soo kabsado titanium. Oo Mararka ay soo kabashada waxaa loo baahan yahay in tiro ku filan oo waaweyn, in uu yahay, waxaan ka hadleynaa heer warshadeed. Waa hanti this of hydride ayaa helay isticmaalka ballaaran ee warshadaha culus oo suuqa baabuurta. hydride Sodium waxaa loo isticmaalaa in metallurgy iyo - xaaladaha kuwa marka waxaa lagama maarmaan ah in loo qoondeeyo xeryahooda kala duwan ee kooxda ka mid ah macdanaha dhif ah, Xoojiya kale oo aan la kala sooci karaa. Waxa uu si firfircoon loo isticmaalaa in qaybaha kale ee dhaqaalaha. Sida laga arki karo ka dhan ah xaqiiqooyinka kor ku xusan, hydride sodium waa xarunta kiimikada ku filan muhiim ah taas oo si weyn loo isticmaalo wax soo saarka warshadaha.

Haddaba dhawr eray oo ku saabsan diyaarinta hydride sodium ee heer warshadeed. In wax soo saarka ee sodium hydride qadar yar oo ah xarunta this hadhay taangiga, oo waxaa bixisey in dusha sare ee sodium la shubay. Taangiga - nuclear-Dufcaddii siman - waa weel gudahood oo ku yaalla fur leh laba garbaha. Iyada oo design this, wax waa la siidaayey gudahood nuclear-ka. Waxaa muhiim ah in lala socdo sahayda of sodium iyo hydrogen, sida la Joogaba, aan sax ahayn ee hydride firfircoon ka leexin kara in wajiga dareere ah. Tani waxay ifafaale qaadan kartaa meel iyo xaaladaha heerkulka qaldan (koror heerkulka ka sarreeya qiimaha la ogolyahay).
