I-sodium borohydride, eyaziwa nangokuthi i-NaBH4, iyinhlanganisela ye-crystalline engenambala enezinhlobonhlobo zezicelo ekuhlanganiseni kwamakhemikhali nokugcinwa kwamandla.Kulesi sihloko, sizoxoxa ngezakhiwo, ukusetshenziswa, kanye nezinzuzo ze-sodium borohydride ngokuningiliziwe.I-Chemical SynthesisI-Sodium borohydride iyi-ejenti yokunciphisa ebalulekile esetshenziswa ezenzweni eziningi ze-organic synthesisreactions ezinciphisa ngokukhetha ama-aldehydes, ama-ketones, ama-carboxylic acid, nama-amide ukukhiqiza uhla lwe izinhlanganisela zamakhemikhali.I-sodium borohydride inezinzuzo ezimbalwa eziyingqayizivele ngaphezu kwamanye ama-ejenti okunciphisa, njengamazinga okusabela okusheshayo, ukuphatha kalula, nokukhetha okuphezulu.Ngakho-ke, isetshenziswa kabanzi ekukhiqizeni izimboni kanye nocwaningo lwezemfundo.Isitoreji SamandlaI-sodium borohydride nayo inezinhlelo zokusebenza ezibalulekile emkhakheni wokugcinwa kwamandla.Ingasetshenziswa njengento yokugcina i-hydrogen ngenxa yomthamo wayo omkhulu wokugcina i-hydrogen kanye nesisindo esincane samangqamuzana.Uma i-sodium borohydride iphendulana namanzi, kukhishwa umthamo omkhulu wegesi ye-hydrogen, engasetshenziselwa amaseli kaphethiloli kanye nezinye izinto zikagesi.Ngaphezu kwalokho, i-sodium borohydride ingashintshwa njenge-electrode material ukuze ishaje futhi ikhishwe ngendlela ejikelezayo, okwenza isebenze ekukhiqizeni amabhethri okugcina amandla aphezulu.Ososayensi bathole ukuthi i-sodium borohydride ingaba i-ejenti ethembisayo yezidakamizwa ezilwa nomdlavuza.I-compound ihlose futhi ibulale ngokukhetha amangqamuzana omdlavuza ngokukhulula ngokushesha ama-ion e-hydrogen asebenzayo, ivimbele ukukhula kwamangqamuzana omdlavuza, nokuhlukana.Ukwengeza, izakhiwo ezinciphisayo ze-sodium borohydride ziye zaboniswa ukuthi zinenzuzo ekususeni ama-radicals mahhala emzimbeni ukuze kugcinwe impilo yonke.Izakhiwo zayo eziyingqayizivele, njengokukhetha kwayo okuphezulu, izinga lokusabela okusheshayo, umthamo omkhulu wokugcina i-hydrogen, kanye nezakhiwo ezinciphisayo, ziyenza ibe inhlanganisela ebalulekile ekukhiqizweni kwezimboni kanye nocwaningo lwezemfundo.Ngokuzayo, ososayensi bazoqhubeka nokuhlola ukusetshenziswa okungenzeka kwe-sodium borohydride emikhakheni ehlukahlukene ukuze kuthuthukiswe futhi kuthuthukiswe izimpilo zethu zansuku zonke.
