I-sodium borohydride yikhompawundi eguquguqukayo ye-inorganic eye yaba yeyona nto iphambili kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa.Yinto emhlophe ye-crystalline kunye ne-chemical formula NaBH4 equkethe i-sodium cations kunye ne-borohydride anions.Le khompawundi yaziwa ngokukwazi ukunciphisa iikhompawundi ezahlukeneyo eziphilayo kunye ne-inorganic, iyenza i-reagent eyaziwayo kwiilebhu zekhemistri.
I-sodium borohydrideisetyenziswa ikakhulu njenge-arhente yokunciphisa kwi-organic synthesis.Inciphisa ngokufanelekileyo i-ketones kunye ne-aldehydes kwii-alcohols zazo, elinyathelo eliphambili ekwenzeni iziyobisi, iziqholo kunye neziqholo.Le khompawundi ikwasetyenziswa kwezinye reactions zokwenziwa ezifana esterification, amidation kunye alkylation.Kwezi nkqubo, i-borohydride yesodium ngumthombo ogqwesileyo we-hydrogen ukuguqula ii-reactants zibe yimveliso emitsha.
Ukongeza kwi-reagent eqhelekileyo kwi-organic chemistry,sodium borohydrideiyasebenza kwamanye amashishini afana nezamandla kunye nezolimo.Kungekudala, abaphandi baye bahlola ukusetyenziswa kwe-sodium borohydride kwiinkqubo zokugcina i-hydrogen kwiimoto zeeseli zamafutha.Iiseli zamafutha e-Hydrogen zithathwa njengenye indlela ezinzileyo kumafutha efosili yemveli kuba zitshisa zicocekile kwaye zivelisa amanzi kuphela njengemveliso.Nangona kunjalo, ukugcina i-hydrogen ngendlela ekhuselekileyo nesebenzayo kulucelomngeni.Kulapho i-sodium borohydride ingena khona njengesisombululo esinokwenzeka kuba ikhupha igesi ye-hydrogen xa ishushu.
Kwezolimo, i-sodium borohydride isetyenziswa njengesibulali zinambuzane ukulawula izitshabalalisi ezifana neempukane.Le khompawundi ikhupha igesi yehydrogen xa idibana namanzi okanye ukufuma emoyeni.Irhasi yehydrogen eveliswayo iyityhefu kwizinambuzane, nto leyo eyenza ibe sisibulali-zinambuzane esisebenzayo.Isodium borohydride ikwasetyenziswa njengesilungiso somhlaba kuba yonyusa ipH yomhlaba kwaye iphucula umthamo wawo wokubamba amanzi.
Nangonasodium borohydrideinezicelo ezininzi, iinkxalabo zihleli malunga nemveliso kunye nokusetyenziswa kwayo.Inkqubo yokuvelisa ibandakanya ukusabela kwe-sodium hydride kunye ne-boron trioxide, ekhupha ubushushu obuninzi kwaye idinga amanyathelo afanelekileyo okukhusela ukuphepha ukuqhuma.Ngapha koko, xa i-sodium borohydride isetyenzisiwe, iimveliso zayo zinokuchaphazela kakubi indalo.Ngoko ke, iindlela ezifanelekileyo zokulahla kufuneka zisetyenziswe ukuthintela ukungcoliseka kweenkqubo zomhlaba namanzi.
Isishwankathelo,sodium borohydrideyikhompawundi eguquguqukayo efumene izicelo kumashishini aliqela, kubandakanya i-organic synthesis, amandla, kunye nezolimo.Iimpawu zayo ezikhethekileyo zokunciphisa kunye nokukwazi ukukhulula i-hydrogen yenza ukuba ibe sisixhobo esibalulekileyo kwi-chemical reactions, iteknoloji yeeseli zamafutha kunye nokulawula izinambuzane.Nangona kunjalo, ukuveliswa kunye nokusetyenziswa kwayo kufuneka kulawulwe ngononophelo ukuqinisekisa ukhuseleko kunye nokunciphisa iimpembelelo ezimbi zokusingqongileyo.
