Potassium borohydride, inozivikanwawo seKBH4, ikemikari inoshanduka-shanduka uye inokosha inoita basa rakakosha mukuita kwakasiyana-siyana kwemakemikari. Kemikari iyi inoshandiswa zvakanyanya mukugadzirwa kwezvinhu zvakasikwa, mishonga, uye semushonga unodzikisa mumabasa mazhinji emaindasitiri. Mublog rino, tichaongorora hunhu uye mashandisirwo epotassium borohydride uye kukosha kwayo mumunda wekemikari.
Potassium borohydrideihupfu hwemakristaro machena hunonyungudika zvikuru mumvura. Imusanganiswa wakasimba mumamiriro ezvinhu akajairwa, asi unoshanda pamwe chete nemvura nemaacids, zvichiburitsa gasi rehydrogen. Hunhu uhwu hunoiita kuti ive chinhu chinodzikisa simba mukuita kwemakemikari. Chimwe chezvinhu zvakakosha zvekushandisapotasium borohydridekushandiswa kwayo senzira yekuderedza maaldehydes nemaketones kuita maalcohols. Maitiro aya anoshandiswa zvakanyanya mukugadzirwa kwemakemikari akasiyana-siyana eorganic, anosanganisira mishonga, zvinonhuhwirira, uye makemikari akanaka.
Pamusoro pebasa rayo semushonga wekuderedza huwandu hwezvinhu,potasium borohydrideInoshandiswawo mukugadzira masimbi uye sechinhu chinobatsira mukuita kwemakemikari. Imusanganiswa unoshanda zvakasiyana-siyana unogona kushandiswa mumhando dzakasiyana dzemakemikari, zvichiita kuti ive chinhu chakakosha mukushandisa kwemakemikari ekugadzira uye vaongorori vemaindasitiri.
Chimwe chezvinhu zvinonyanya kukosha zvepotasium borohydrideine huwandu hwakawanda hwehydrogen. Izvi zvinoita kuti ive mukana wekuchengetera hydrogen uye kushandiswa kwemaseru emafuta. Tsvagiridzo iri kuenderera mberi yekuongorora kugona kwepotasium borohydridesenzvimbo yehydrogen yemasero emafuta, izvo zvinogona kuva nemigumisiro yakakosha kune matekinoroji esimba rakachena.
Uyezve,potasium borohydrideYakawana mashandisirwo ainoita muzvidzidzo zvesainzi yezvinhu, kunyanya mukugadzirwa kwezvinhu zvenanomaterials nesimbi. Kugona kwayo kushanda semushonga unodzikisa uye sosi yehydrogen kunoita kuti ive chinhu chinokosha pakugadzirwa kwezvinhu zvepamusoro zvine hunhu hwakasiyana uye mashandisirwo azvo.
Zvakakosha kucherechedza kuti nepopotasium borohydrideine mashandisirwo akawanda, inodawo kubatwa nokungwarira nekuda kwekuita kwayo pamwe chete nemvura nemaacids. Matanho akakodzera ekuchengetedza uye maitiro ekubata anofanirwa kuteverwa pakushanda nechinhu ichi kuti pave nechokwadi chekuti vashandi vemurabhoritari vakachengeteka uye kuti maitiro ekuyedza akavimbika.
Mukupedzisa,potasium borohydridechinhu chinoshandiswa zvakasiyana-siyana uye chinokosha chine mashandisirwo akasiyana-siyana mukugadzirwa kwemakemikari, sainzi yezvinhu, uye matekinoroji esimba rakachena. Basa rayo semushonga unoderedza uye sosi yehydrogen rinoita kuti ive chishandiso chakakosha kune vaongorori nevanoongorora makemikari emaindasitiri. Sezvo kunzwisisa kwedu hunhu hwayo uye mashandisirwo ayo ari kuramba achikura,potasium borohydridezvingangoita basa rakakosha zvikuru mukuumba remangwana resainzi yekemikari nezvinhu.
