Ukuhlanganiswa kwamakhemikhali kuyisici esibalulekile socwaningo lwesimanje lwesayensi kanye nokukhiqizwa kwezimboni. Kubandakanya ukukhiqizwa kwamakhompiyutha amasha okusabela okuhlukahlukene kwamakhemikhali, kanye ne-realent eyodwa yokhiye odlala indima ebalulekile kule nqubo yi-sodium cyanoborohydride.
Sodium cyanoborohydride, ngefomula yamakhemikhali nabh3cn, i-ejenti eqinile eqinile eqinile esetshenziswa kakhulu kumakhemikhali we-organic. Ibaluleke kakhulu ngekhono layo lokunciphisa ama-aldehydes nama-ketones azokwala izimo zawo, okwenza kube yithuluzi elibalulekile ekuhlanganiseni kwamakhamishini, amakhemikhali amahle, nezinye izibopho ze-organic.
Enye yezinzuzo eziphambili zokusebenzisa i-sodium cyanoborohydride njengo-ejenti oncishisiwe yizimo zayo zokusabela ezimnene. Ngokungafani namanye ama-ejenti asetshenziswa kakhulu asetshenziswa njenge-Lithium aluminium hydride,sodium cyanoborohydrideIsebenza ngaphansi kwezimo eziphithizelayo, okwenza kuphephe futhi kube lula ukusebenzisa izilungiselelo zelebhu. Lobumnene futhi uvumela ukulawula okungcono kokusabela, ukunciphisa ubungozi bokuphendula okungafuneki okuhlangenwe nakho noma ukuncishiswa ngokweqile kwamakhompiyutha okuhlosiwe.
Enye inzuzo enkulu yesodium cyanoborohydrideukukhetha kwayo okuphezulu. Lapho kusetshenziselwa ukunciphisa amakhompiyutha e-carbonyl, ngokuvamile kugwema ukuphazamisa amanye amaqembu asebenzayo akhona ku-molecule, okuholela ekuphenduleni okuhlanzekile nokusebenza kahle. Lokhu kukhetha kubalulekile ekuhlanganiseni kwama-molekyuli ayinkimbinkimbi ezi-organic, lapho ukulondolozwa kwamanye amaqembu asebenzayo kuvame ukuba kubucayi ukwakheka kwamakhemikhali kanye nezakhiwo ezifunwayo.
Ngaphezu kokuba ngumenzeli oncishisiwe,sodium cyanoborohydrideingasetshenziswa kwezinye izinguquko zamakhemikhali. Ingasetjenziselwa ama-arainate avuselelayo ama-aldehydes nama-ketones, kanye nokuhlanganiswa kwezihlanganisi ezahlukahlukene ze-heterocyclic. Ukuguquguquka kwayo kanye nokuhambisana namaqembu ahlukahlukene asebenzayo kwenza kube yithuluzi elibalulekile kosokhemisi ababhekene nezinselelo ezahlukahlukene zokwenziwa.
Ngokwengeziwe,sodium cyanoborohydrideyaziwa ngokuqina kwayo kanye nokuphathwa kalula. Ngokungafani namanye ama-reagents okusabela, kungagcinwa futhi kuhanjiswe ngaphandle kwezindlela zokuphepha ngokweqile, okwenza kube khona ngokwengeziwe ezilungiselelweni zezifundo kanye nezimboni.
Nokhosodium cyanoborohydrideInezinzuzo eziningi, kubalulekile ukuqaphela ukuthi, njenganoma yimuphi umenzeli wamakhemikhali, kufanele isetshenziswe ngokunakekelwa nokulandela izinqubo ezifanele zokuphepha. Yize kuthathwa njengephephe kunenye ama-ejenti ancishisiwe ancishisiwe, kusenziwa izinyathelo zamakhemikhali ezinamandla nezifanele kufanele zithathwe ngaphansi kokuholwa ngusokhemisi onolwazi.
Ekuphetheni,sodium cyanoborohydrideIdlala indima ebalulekile ekuhlanganiseni kwamakhemikhali, ikakhulukazi ekwehlisweni kwamakhompiyutha e-carbonyl kanye nezinye izinguquko ezihlobene. Izimo zayo ezimnene zokuphendula, ukukhethwa okuphezulu, ukuguquguquka okuhlukahlukene, kanye nokuqina kwenza kube yimpahla ebalulekile kubhokisi lamakhemikhali okwenziwa. Njengoba ucwaningo nentuthuko emkhakheni wamakhemikhali we-organic kuyaqhubeka ukuqhubekisela phambili, ukubaluleka kwesodium cyanoborohydrideNgokunika amandla ukuguqulwa okusha kwamakhemikhali kanye nokuhlanganiswa kwamakhoqha wenoveli kungenzeka ukuthi kugcinwe kubalulekile.
