Potasiyumu borohydride, izwi kandi nka KBH4, ni imiti itandukanye kandi ikomeye yimiti igira uruhare runini mubitekerezo bitandukanye byimiti. Uru ruganda rukoreshwa cyane muri synthesis organique, farumasi, kandi nkumukozi ugabanya ibikorwa byinshi byinganda. Muri iyi blog, tuzasesengura imiterere nogukoresha potasiyumu borohydride nakamaro kayo mubijyanye na chimie.
Potasiyumu borohydrideni ifu yera ya kristaline yera cyane mumazi. Nibintu bihamye mubihe bisanzwe, ariko ntibishobora gukoreshwa namazi na acide, birekura gaze ya hydrogen. Uyu mutungo ubigira imbaraga zikomeye zo kugabanya imiti. Imwe mumfunguzo zingenzi zapotasiyumu borohydrideni ikoreshwa ryayo nka reagent yo kugabanya aldehydes na ketone kuri alcool. Iyi reaction ikoreshwa cyane muguhuza ibice bitandukanye kama, harimo imiti, impumuro nziza, hamwe nimiti myiza.
Usibye uruhare rwayo nkumukozi ugabanya,potasiyumu borohydrideikoreshwa kandi mugukora ibyuma bya boride kandi nkumusemburo mubikorwa bya organic. Nibintu byinshi bishobora gukoreshwa muburyo butandukanye bwimiti, bigatuma iba ikintu cyingenzi mubitabo byabashakashatsi ba chimique nubushakashatsi bwinganda.
Kimwe mu bintu bigaragara birangapotasiyumu borohydrideni hydrogène nyinshi. Ibi bituma iba umukandida ushimishije kubika hydrogène hamwe na peteroli ikoreshwa. Ubushakashatsi burakomeje kugirango bushakishe ubushobozi bwapotasiyumu borohydridenkisoko ya hydrogène yingirabuzimafatizo, zishobora kugira ingaruka zikomeye muburyo bwikoranabuhanga rifite ingufu.
Byongeye kandi,potasiyumu borohydrideyabonye porogaramu mubijyanye nibikoresho siyanse, cyane cyane muri synthesis ya nanomateriali na nanoparticles. Ubushobozi bwayo bwo gukora nkibintu bigabanya isoko ya hydrogène bituma iba intangiriro yingirakamaro yo gukora ibikoresho bigezweho bifite imiterere yihariye nibisabwa.
Ni ngombwa kumenya ko mugihepotasiyumu borohydrideifite porogaramu nyinshi, irasaba kandi kwitonda neza kubera reaction yayo n'amazi na acide. Uburyo bukwiye bwo kwirinda umutekano hamwe nuburyo bukoreshwa bigomba gukurikizwa mugihe ukorana nuru ruganda kugirango umutekano w abakozi ba laboratoire nubusugire bwibikorwa byubushakashatsi.
Mu gusoza,potasiyumu borohydrideni ibintu byinshi kandi bifite agaciro hamwe nuburyo butandukanye bwo gukoresha imiti, ibikoresho bya siyansi, hamwe n’ikoranabuhanga rifite ingufu. Uruhare rwarwo rwo kugabanya no kuba isoko ya hydrogène bituma iba igikoresho cyingirakamaro kubashakashatsi naba chimiste mu nganda. Mugihe twunvikana kumiterere yabyo nibishobora gukoreshwa bikomeje kwiyongera,potasiyumu borohydridebirashoboka kugira uruhare runini mugushiraho ejo hazaza ha chimie nibikoresho siyanse.
