Sodium borohydrideihupfu hwemakristaro machena hune fomura yemakemikari NaBH4. Inoderedza simba rinoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kwehunhu hwayo hwakasiyana uye kushanduka-shanduka. Musanganiswa uyu hausi chete wakakosha mumakemikari echisikigo, asiwo unoita basa rakakosha mukugadzira, mashandisirwo ezvakatipoteredza, uye kunyangwe mishonga. Mublog rino, tichaongorora mashandisirwo akasiyana-siyana e sodium borohydride uye kukosha kwayo muminda yakasiyana.
Zvinoderedza zvinhu mumakemikari echisikigo
Imwe yenzira huru dzekushandisa sodium borohydride ibasa rayo semushonga wekuderedza makemikari emu organic. Inonyanya kushanda mukuderedza ma aldehydes nema ketones kune ma alcohols anoenderana. Kuita uku kwakakosha pakugadzirwa kwemhando dzakasiyana dzemakemikari emu organic, zvichiita kuti sodium borohydride ive chinhu chikuru murabhoritari nemumaindasitiri. Kugona kwayo kuderedza mapoka anoshanda kunogonesa ma chemical kugadzira mamorekuru akaomarara nemazvo, zvichiita kuti ive chishandiso chakakosha mumunda we organic synthesis.
Zvinhu zvikuru zvinoshandiswa mumushonga uyu
Sodium borohydrideinoshandiswawo muindasitiri yemishonga, kunyanya semushonga wehydrogenating we dihydrostreptomycin, mushonga unorwisa mabhakitiriya unoshandiswa kurapa TB. Maitiro ekuderedza anokurudzirwa ne sodium borohydride akakosha pakugadzirwa kwemushonga uyu unokosha. Pamusoro pezvo, sodium borohydride inogonawo kushandiswa sechikamu chepakati mukugadzirwa kwePBH (polyborohydride) uye inoshandiswa mumabasa akasiyana-siyana emakemikari. Basa rayo mukurapa rinoratidza kukosha kwe sodium borohydride mukugadzirwa kwemishonga inoponesa hupenyu.
Kuvandudza maitiro ekugadzira
Mukugadzira,sodium borohydrideinoshandiswa sepurasitiki inoputira. Kushandiswa uku kwakakosha zvikuru pakugadzira zvinhu zvepurasitiki zvakareruka uye zvinogara kwenguva refu. Nekuwedzera sodium borohydride panguva yekugadzira, kambani inogona kugadzira furo risingangove rakasimba chete asiwo rine hunhu hwakanaka hwekudzivirira kupisa. Kuvandudzwa uku kwakakurudzira kugadzirwa kwezvigadzirwa kubva pazvinhu zvekurongedza kusvika kuzvikamu zvemota.
Kushandiswa Kwezvakatipoteredza
Sodium borohydrideInoshandiswa kupfuura kushandiswa kwemakemikari echinyakare. Inoshandawo basa rakakosha mukutarisira nharaunda. Imwe nzira inozivikanwa ndeyekurapa mvura yakasviba yemercury. Mercury isimbi ine chepfu ine chepfu inokonzera njodzi huru kunharaunda nehutano. Sodium borohydride inogona kuderedza zvinobudirira maion emercury mumvura yakasviba uye kuashandura kuita mafomu asina kukuvadza. Kushandiswa uku kwakakosha kumaindasitiri anobata nekusvibiswa kwesimbi yakaremara, zvichibatsira kuderedza kusvibiswa kwenharaunda uye kuchengetedza ecosystems.
Basa muindasitiri yemapepa
Indasitiri yemapepa inozivawo mabhenefiti e sodium borohydride. Inoshandiswa mukuita bleaching kubatsira kuderedza ruvara rwe pulp yehuni, zvichiita kuti pave nepepa rakajeka uye jena. Kushandiswa uku hakungogadzirisi mhando yechigadzirwa chekupedzisira chete asiwo kunobatsira mukuita zvinhu zvinogara kwenguva refu nekuderedza kudiwa kwemakemikari akaomarara mukuita bleaching.
Sodium borohydridemusanganiswa unoshamisa une mashandisirwo akasiyana-siyana mumaindasitiri akasiyana-siyana. Kubva pabasa rayo semushonga wekuderedza mumakemikari echisikigo kusvika pakushandiswa mumishonga, kugadzira, manejimendi yezvakatipoteredza uye kugadzira mapepa, sodium borohydride yaratidza kuva chishandiso chakakosha musainzi yemazuva ano nemaindasitiri. Sezvo tsvakurudzo ichiramba ichiwana mashandisirwo matsva emusanganiswa uyu unoshanduka-shanduka, kukosha kwawo kunogona kuwedzera, zvichiita kuti uve mutambi mukuru mukutsvaga hunyanzvi uye kugara kwenguva refu. Kunyangwe uri nyanzvi yemakemikari, mugadziri, kana nyanzvi yezvakatipoteredza, kunzwisisa mashandisirwo akawanda e sodium borohydride kunogona kupa ruzivo rwakakosha pamusoro pemhedzisiro yayo panyika yedu.
