Potassium borohydride, eyaziwa nangokuthi i-KBH4, iyingxenye yamakhemikhali eguquguqukayo futhi ebalulekile edlala indima ebalulekile ekuphendukeni okuhlukahlukene kwamakhemikhali. Le mpikiswano isetshenziswa kabanzi ekuhlolweni kwe-organic, ezemithi, nanjengomenzeli oncishisiwe ezinkambisweni eziningi zezimboni. Kule bhulogi, sizohlola izakhiwo kanye nokusetshenziswa kwe-potassium borohydride nokubaluleka kwaso emkhakheni wamakhemikhali.
Potassium borohydrideyimpuphu ye-crystalline emhlophe enyakazisa kakhulu emanzini. Kuyindlela ezinzile ngaphansi kwezimo ezijwayelekile, kepha iyasebenza ngamanzi nama-acid, ukukhulula igesi ye-hydrogen. Le mpahla yenza kube yi-ejenti enamandla yokunciphisa ukusabela kwamakhemikhali. Enye yezinhlelo zokusebenza ezibalulekile zepotassium borohydrideukusetshenziswa kwayo njenge-realent yokwehliswa kwama-aldehydes nama-ketones ku-alcohols. Lokhu kusabela kusetshenziswa kabanzi ekuhlanganiseni kwamakhompiyutha ahlukahlukene a-organic, kufaka phakathi amakhambi, amakha namakhemikhali amahle.
Ngaphezu kwendima yayo njengomenzeli oncishisiwe,potassium borohydrideisetshenziswa futhi ekukhiqizweni kwezimpawu zensimbi kanye ne-catalyst ekuphendukeni kwe-organic. Kuyindawo eguquguqukayo engaqashwa ngezinqubo eziningi zamakhemikhali, okwenza kube yingxenye ebalulekile ku-tollkit yamakhemikhali okwenziwa kanye nabacwaningi bezimboni.
Enye yezinto eziphawuleka zepotassium borohydrideokuqukethwe kwayo okuphezulu kwe-hydrogen. Lokhu kwenza kube yilowo okhethwa okhangayo we-hydrogen isitoreji kanye nezinhlelo zokusebenza zamaselula. Ucwaningo luyaqhubeka ukuhlola amandla wepotassium borohydrideNjengomthombo we-hydrogen amaseli kaphethiloli, angaba nemiphumela ebalulekile yobuchwepheshe obuhlanzekile wamandla.
Ngaphezu kwalokho,potassium borohydrideUthole izicelo emkhakheni wesayensi yezinto zokwakha, ikakhulukazi ekuhlanganiseni kwama-nanomatadium kanye nama-nanoparticles wensimbi. Amandla awo okwenza i-ejenti encishisiwe futhi umthombo we-hydrogen wenza kube yisandulelo esibalulekile ekukhiqizweni kwezinto ezithuthukile ezinezakhiwo ezihlukile nezinhlelo zokusebenza.
Kubalulekile ukuqaphela ukuthi ngenkathipotassium borohydrideInezicelo eziningi, nayo idinga ukuphatha ngokucophelela ngenxa yokuvuselelwa kwayo ngamanzi nama-acid. Izindlela zokuphepha zokuphepha kanye nezinqubo zokuphatha kufanele zilandelwe lapho zisebenza nale nhlanganisela ukuqinisekisa ukuphepha kwabasebenzi belebhu kanye nobuqotho benqubo yokuhlola.
Ekuphetheni,potassium borohydrideiyingxenye eguquguqukayo nelibalulekile enobubanzi bezicelo ku-synthesis yamakhemikhali, isayensi yezinto zokwakha, kanye nobuchwepheshe obuhlanzekile be-Energy. Indima yayo njengomenzeli oncishisiwe kanye nomthombo we-hydrogen yenza kube yithuluzi elibaluleke kakhulu labacwaningi kanye namakhemikhali ezimboni. Njengoba ukuqonda kwethu izakhiwo zayo nezinhlelo zokusebenza ezingaba khona ziyaqhubeka zikhula,potassium borohydridekungenzeka ukuthi udlale iqhaza elibaluleke kakhulu ekubumbeni ikusasa lamakhemikhali kanye nesayensi yezinto zokwakha.
