I-sodium borohydridei-white crystalline powder ene-chemical formula NaBH4. Kuyi-ejenti yokunciphisa enamandla esetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo eziyingqayizivele kanye nokuhlukahluka. Le nhlanganisela ayibalulekile kuphela kumakhemikhali wezinto eziphilayo, kodwa futhi idlala indima ebalulekile ezinqubweni zokukhiqiza, ukusetshenziswa kwemvelo, ngisho nemithi. Kule bhulogi, sizohlola ukusetshenziswa okuxubile kwe-sodium borohydride nokubaluleka kwayo emikhakheni ehlukene.
Ama-ejenti okunciphisa ku-organic chemistry
Enye yezinhlelo zokusebenza eziyinhloko ze-sodium borohydride indima yayo njenge-ejenti yokunciphisa kumakhemikhali wemvelo. Isebenza kahle kakhulu ekwehliseni ama-aldehydes nama-ketones kuma-alcohols ahambisanayo. Lokhu kusabela kubalulekile ekuhlanganisweni kohlu olubanzi lwenhlanganisela yezinto eziphilayo, okwenza i-sodium borohydride ibe impahla eluhlaza eyinhloko endaweni yaselabhorethri nezimboni. Ikhono layo lokunciphisa ngokukhetha amaqembu asebenzayo lenza osokhemisi bakwazi ukudala ama-molecule ayinkimbinkimbi ngokunemba, okwenza kube ithuluzi elibalulekile emkhakheni we-organic synthesis.
Izithako eziyinhloko zomuthi
I-sodium borohydrideibuye isetshenziswe embonini yezemithi, ikakhulukazi njenge-hydrogenating ejenti ye-dihydrostreptomycin, isibulala-magciwane esisetshenziselwa ukwelapha isifo sofuba. Inqubo yokunciphisa ekhuthazwa yi-sodium borohydride ibalulekile ekukhiqizweni kwalo muthi obalulekile. Ngaphezu kwalokho, i-sodium borohydride ingasetshenziswa futhi njengendawo ephakathi ekukhiqizeni i-PBH (i-polyborohydride) futhi isetshenziselwa izinqubo ezihlukahlukene zamakhemikhali. Indima yayo kwezokwelapha igqamisa ukubaluleka kwe-sodium borohydride ekuthuthukisweni kwezidakamizwa ezisindisa impilo.
Thuthukisa inqubo yokukhiqiza
Kwezokukhiqiza,i-sodium borohydrideisetshenziswa njenge-ejenti yokufutha epulasitiki. Lolu hlelo lokusebenza lubaluleke kakhulu ekukhiqizeni izinto zepulasitiki ezingasindi neziqinile. Ngokungeza i-sodium borohydride ngesikhathi sokukhiqiza, inkampani ingakha igwebu elingenamandla kuphela kodwa futhi linezakhiwo ezinhle kakhulu zokuvikela. Lokhu kusungula kugqugquzele ukuthuthukiswa kwemikhiqizo esukela ezintweni zokupakisha kuya kuzingxenye ezizenzakalelayo.
Isicelo sezemvelo
I-sodium borohydrideinokusebenzisa okungaphezu kokusetshenziswa kwamakhemikhali endabuko. Iphinde idlale indima ebalulekile ekuphathweni kwemvelo. Isicelo esisodwa esiphawulekayo sinjenge-ejenti yokuhlanza amanzi angcolile e-mercury. I-Mercury iyinsimbi enobuthi eyingozi ebeka engcupheni enkulu emvelweni nempilo. I-sodium borohydride inganciphisa ngempumelelo ama-ion e-mercury emanzini angcolile futhi iwaguqule abe amafomu ayingozi kancane. Lolu hlelo lokusebenza lubalulekile ezimbonini ezibhekene nokungcoliswa kwensimbi, esiza ukunciphisa ukungcoliswa kwemvelo nokuvikela imvelo.
Iqhaza embonini yamaphepha
Imboni yephepha iphinde ibone izinzuzo ze-sodium borohydride. Isetshenziswa enkambweni yokufiphaza ukuze isize ukunciphisa umbala we-pulp yezinkuni, okuholela ekukhanyeni, umkhiqizo wephepha omhlophe. Lolu hlelo lokusebenza aluthuthukisi nje kuphela ikhwalithi yomkhiqizo wokugcina kodwa futhi lufaka isandla ezenzweni ezizinzile ngokunciphisa isidingo samakhemikhali anokhahlo enqubweni yokushibilika.
I-sodium borohydrideiyinhlanganisela ephawulekayo enohlu olubanzi lwezinhlelo zokusebenza kuzo zonke izimboni ezihlukahlukene. Kusukela endimeni yayo njenge-ejenti yokunciphisa ku-organic chemistry kuya ekusetshenzisweni kwemithi, ukukhiqiza, ukuphathwa kwemvelo kanye nokwenza iphepha, i-sodium borohydride ibonakale iyithuluzi elibalulekile kwisayensi yesimanje kanye nezimboni. Njengoba ucwaningo luqhubeka nokuthola ukusetshenziswa okusha kwale nhlanganisela ehlukahlukene, ukubaluleka kwayo kungenzeka kukhule, okuyenza ibe ngumdlali oyinhloko ekuphishekeleni okuqhubekayo kokuqamba okusha kanye nokusimama. Noma ngabe ungusokhemisi, umkhiqizi, noma isazi sezemvelo, ukuqonda ukusetshenziswa okuningi kwe-sodium borohydride kunganikeza imininingwane ebalulekile ngomthelela wayo emhlabeni wethu.
