I-Potassium borohydride, eyaziwa nangokuthi i-KBH4, iyinhlanganisela yamakhemikhali ehlukahlukene futhi ebalulekile edlala indima ebalulekile ekuphenduleni kwamakhemikhali okuhlukahlukene. Le nhlanganisela isetshenziswa kabanzi ku-organic synthesis, kwezemithi, nanjenge-ejenti yokunciphisa ezinqubweni eziningi zezimboni. Kule bhulogi, sizohlola izakhiwo kanye nokusetshenziswa kwe-potassium borohydride kanye nokubaluleka kwayo emkhakheni wamakhemikhali.
I-Potassium borohydridei-white crystalline powder encibilika kakhulu emanzini. Kuyinhlanganisela ezinzile ngaphansi kwezimo ezijwayelekile, kodwa iyasebenza ngamanzi nama-asidi, ikhipha igesi ye-hydrogen. Lesi sakhiwo sikwenza kube i-ejenti yokunciphisa enamandla ekuphenduleni kwamakhemikhali. Enye yezinhlelo zokusebenza ezibalulekile zei-potassium borohydrideukusetshenziswa kwayo njenge-reagent yokunciphisa ama-aldehydes nama-ketones otshwaleni. Lokhu kusabela kusetshenziswa kabanzi ekuhlanganiseni izinhlanganisela ezihlukahlukene zezinto eziphilayo, okuhlanganisa imithi, amakha, namakhemikhali amahle.
Ngaphezu kwendima yayo njenge-ejenti yokunciphisa,i-potassium borohydrideiphinde isetshenziswe ekukhiqizeni i-borides yensimbi futhi njenge-catalyst ekuphenduleni kwezinto eziphilayo. Kuyinhlanganisela eguquguqukayo engasetshenziswa ezinhlobonhlobo zezinqubo zamakhemikhali, okuyenza ibe yingxenye ebalulekile kukhithi yamathuluzi yosokhemisi bokwenziwa kanye nabacwaningi bezimboni.
Esinye sezici eziphawulekayo zei-potassium borohydrideokuqukethwe kwayo kwe-hydrogen ephezulu. Lokhu kuyenza ibe ikhandidethi elikhangayo lokugcina i-hydrogen kanye nezicelo zamaseli kaphethiloli. Ucwaningo luyaqhubeka ukuhlola amandla ei-potassium borohydridenjengomthombo we-hydrogen wamaseli kaphethiloli, okungaba nemithelela ebalulekile kubuchwepheshe bamandla ahlanzekile.
Ngaphezu kwalokho,i-potassium borohydrideithole izinhlelo zokusebenza emkhakheni wesayensi yezinto, ikakhulukazi ekuhlanganiseni ama-nanomaterials nama-nanoparticles ensimbi. Ikhono layo lokusebenza njenge-ejenti yokunciphisa kanye nomthombo we-hydrogen kwenza kube isandulela esibalulekile sokukhiqizwa kwezinto ezithuthukisiwe ezinezakhiwo eziyingqayizivele kanye nezicelo.
Kubalulekile ukuqaphela ukuthi ngenkathii-potassium borohydrideinezinhlelo zokusebenza eziningi, idinga nokuphathwa ngokucophelela ngenxa yokuphinda isebenze ngamanzi nama-asidi. Izinyathelo zokuphepha ezifanele kanye nezinqubo zokuphatha kufanele zilandelwe lapho usebenza nale khompiyutha ukuze kuqinisekiswe ukuphepha kwabasebenzi baselabhorethri kanye nobuqotho benqubo yokuhlola.
Ekuphetheni,i-potassium borohydrideiyinhlanganisela eguquguqukayo nebalulekile enezinhlobonhlobo zokusetshenziswa ekuhlanganiseni kwamakhemikhali, isayensi yezinto ezibonakalayo, nobuchwepheshe bamandla ahlanzekile. Iqhaza layo njenge-ejenti yokunciphisa kanye nomthombo we-hydrogen iyenza ibe yithuluzi elibalulekile kubacwaningi nosokhemisi bezimboni. Njengoba ukuqonda kwethu izakhiwo zayo kanye nezicelo ezingase zibe khona kuqhubeka kukhula,i-potassium borohydridecishe izodlala indima ebaluleke kakhulu ekulolongeni ikusasa lamakhemikhali nesayensi yezinto zokwakha.
