Yintoni iCalcium hydride

I-calcium hydride yikhemikhali ene-formula CaH2. Yinto emhlophe, eqinileyo eyikristale esebenza kakhulu kwaye iqhele ukusetyenziswa njengearhente yokomisa kwi-organic synthesis. Ikhompawundi yenziwe nge-calcium, isinyithi, kunye ne-hydride, i-ion ye-hydrogen ehlawuliswa kakubi. I-calcium hydride iyaziwa ngokukwazi kwayo ukusabela emanzini ukuvelisa igesi ye-hydrogen, iyenza i-reagent eluncedo kwiindlela ezahlukeneyo zemichiza.

Enye yezinto eziphambili ze-calcium hydride kukukwazi ukufunxa ukufuma emoyeni. Oku kwenza i-desiccant esebenzayo, okanye i-ejenti yokomisa, kwi-laboratory kunye nezicwangciso zoshishino. Xa ibonakaliswe kubumanzi, i-calcium hydride isabela emanzini ukuze yenze i-calcium hydroxide kunye negesi ye-hydrogen. Le ndlela yokusabela ikhupha ubushushu kwaye inceda ukususa amanzi kwindawo engqongileyo, iyenze ibe luncedo ukomisa izinyibilikisi nezinye izinto.

Ukongeza ekusebenziseni kwayo njenge-ejenti yokomisa, i-calcium hydride isetyenziselwa ukuveliswa kwegesi ye-hydrogen. Xa icalcium hydride icocwa ngamanzi, ifumana ikhemikhali ekhupha igesi yehydrogen. Le nkqubo, eyaziwa ngokuba yi-hydrolysis, yindlela efanelekileyo yokuvelisa i-hydrogen kwilabhoratri. Irhasi yehidrojeni eveliswayo ingasetyenziswa kwiinkqubo ezahlukeneyo, kubandakanywa iiseli zepetroli kunye ne-arhente yokunciphisa ukusabela kweekhemikhali.

I-calcium hydride iphinda isetyenziswe kwi-synthesis ye-organic compounds. Ukukwazi kwayo ukususa amanzi kwimixube yokusabela kwenza ukuba ibe sisixhobo esixabisekileyo kwi-organic chemistry. Ngokusebenzisa i-calcium hydride njenge-ejenti yokomisa, iikhemisti zinokuqinisekisa ukuba ukusabela kwazo kuqhubeka phantsi kweemeko ezingenamanzi, ezihlala zibalulekile kwimpumelelo yeempendulo ezithile.

Ukuqukumbela, i-calcium hydride iyikhompawundi eguquguqukayo enoluhlu lwezicelo ezibalulekileyo kwikhemistri. Ukukwazi kwayo ukufunxa ukufuma kunye nokukhupha igesi ye-hydrogen yenza ukuba ibe sisixhobo esibalulekileyo kubaphandi kunye namachiza amashishini ngokufanayo. Nokuba isetyenziswa njengearhente yokomisa, umthombo werhasi yehydrogen, okanye i-reagent kwi-organic synthesis, i-calcium hydride idlala indima ebalulekileyo kwinkalo yekhemistri.
