Ndi sodium hydride. The katundu ndi malongosoledwe a ntchito.

Musanayambe kuthetsa zimene zimatha hydride sodium, m'pofunika mukudziwa chimene icho chiri, kumene ntchito ndi n'kofunika. Mafunso amenewa adzayankhidwa si aliyense Komabe, umbuli mwa zinthu zimenezi sakunena za kulephera kwa thunthu. Monga mankhwala ena sodium, izo chimagwiritsidwa ntchito makampani.

Yesetsani kumvetsa nkhani, ndipo tiyeni tiyambire ndi tanthauzo ndi malongosoledwe a pawiri lapansi. Choncho, sodium hydride - kuipidwa zochita kupanga mankhwala ndi chilinganizo Nah, grayish-loyera kapena zoyera hygroscopic ufa. Konzekerani ndi zimene yogwira mtima wake ndi mu madzi ndi inert mpweya wa hydrogen ndi zachitsulo sodium wochuluka. Ikani mankhwala kwa karboksidirovaniya, alkylation ndi acylation wa ofooka C-H-acid. Mogwirizana pawiri ndi madzi amapereka hydroxide njira (hydroxide sodium, ndi sodium hydroxide).

Kotero, tsopano mwachindunji pa katundu wa hydride ndi sodium. Choyamba, ndi ndale za zitsulo, amene m'mikhalidwe muyezo timakhala dzimbiri. Pamene ntchito mankhwala, ngakhale mitundu yonse ya zimakhalapo, roughness ndi zopindika pamwamba akunja zitsulo, izo anagawira uniformly ndi kuteteza pamwamba. ndi sodium hydride, amene ntchito mafuta mchere kapena chimasanduka zina mwa mawonekedwe a suspensions. Pakuti zovuta izi ziyenera usavutike madigiri 100. Sodium hydride chimasungunula pa madigiri 800 Celsius, koma izi zimachitika zokha opanikizika.

nkhaniyi, komanso kashiamu hydride, titaniyamu ndi zirconium, zotsatira zabwino pa vulcanizates mphira. Mu amenewa kutumikiridwa asanalankhule ndondomeko vulcanization mu mawonekedwe a dispersions mu petrolatum, paraffin kapena mafuta mchere. Sodium hydride ena thupi katundu zofanana ndi sodium kolorayidi, koma kupanga ake ndi pang'ono ankawonjezereka ndi okwera mtengo kwambiri. Choncho, kuchuluka kwa sodium wochuluka hydride wapadera katundu chifukwa chimene ali okha ndi sodium pawiri. Koma njira mankhwala kuti chichitike ndi nawo sodium kolorayidi ndi sodium wochuluka hydride, kusiyana kwambiri.

Sodium hydride amagwira ntchito kuti achire titaniyamu. Ndipo milandu kumene kuchira chofunika lalikulu zedi mokwanira, ndiye tikulankhula lonse mafakitale. Ndi katundu uyu wa hydride ndi wapeza ntchito kwambiri mu makampani olemera ndi makampani magalimoto. Sodium hydride ntchito zitsulo ndi - milandu amenewa m'pofunika kuonetsetsa mankhwala osiyanasiyana a gulu la zitsulo zina catalysts ena amene sakhoza kuwasiyanitsa. Anamugwiritsa ntchito mwakhama kumabungwe ena a chuma. Monga Tingaone mfundo zonse pamwamba, sodium hydride ndi mokwanira zofunika mankhwala pawiri amene chimagwiritsidwa ntchito mafakitale.

Tsopano mawu ochepa za yokonza hydride ndi sodium mu mlingo mafakitale. Kupanga ndi sodium hydride ping'ono pawiri izi yatsala m'galimoto, ndipo umaperekedwa kwa padziko ndi sodium chosungunula. Thanki - yopingasa mtanda riyakitala - ndi chidebe mkati limene lili ndi wononga ndi masamba awiri. Ndi mamangidwe, chuma ndi akufalitsa mkati riyakitala lapansi. Nkofunika kuwunika mwa kundipatsako kwa soda ndi wa hydrogen, ndi kufanana pachithunzichi wa hydride yogwira angapatutse mu gawo madzi. chodabwitsa Izi zikhoza kutenga malo ndi pa zinthu zolakwika kutentha (kutentha kuwonjezeka pamwamba pa mtengo kololeka).
