Sodium borohydride ndi chinthu chosunthika chomwe chakhala chofunikira m'mafakitale osiyanasiyana chifukwa cha mawonekedwe ake apadera.Ndi chinthu choyera cha crystalline chokhala ndi mankhwala NaBH4 opangidwa ndi sodium cations ndi borohydride anions.Pawiri iyi imadziwika chifukwa cha kuthekera kwake kuchepetsa mitundu yosiyanasiyana ya organic ndi inorganic, ndikupangitsa kuti ikhale yotchuka m'ma laboratories a chemistry.
Sodium borohydrideamagwiritsidwa ntchito makamaka ngati chochepetsera mu kaphatikizidwe ka organic.Amachepetsa bwino ma ketoni ndi aldehydes ku ma alcohols awo, omwe ndi gawo lofunikira popanga mankhwala, zonunkhira ndi zonunkhira.Pawiri iyi imagwiritsidwanso ntchito pazinthu zina zopanga monga esterification, amidation ndi alkylation.Munjira izi, sodium borohydride ndi gwero labwino kwambiri la haidrojeni kuti asinthe zotulutsa kukhala zatsopano.
Kuphatikiza pa kukhala reagent wamba mu organic chemistry,sodium borohydrideimagwira ntchito m'mafakitale ena monga mphamvu ndi ulimi.Posachedwapa, ofufuza akhala akufufuza kugwiritsa ntchito sodium borohydride m'makina osungiramo ma hydrogen pamagalimoto amafuta.Ma cell amafuta a haidrojeni amaonedwa ngati njira yokhazikika kusiyana ndi mafuta azikhalidwe zakale chifukwa amawotcha oyera ndikungotulutsa madzi okha.Komabe, kusunga haidrojeni m'njira yotetezeka komanso yothandiza ndizovuta.Apa ndi pamene sodium borohydride imabwera ngati njira yothetsera chifukwa imatulutsa mpweya wa haidrojeni ikatenthedwa.
Paulimi, sodium borohydride imagwiritsidwa ntchito ngati mankhwala ophera tizirombo monga ntchentche.Kapangidwe kameneka kamatulutsa mpweya wa haidrojeni pamene uchita ndi madzi kapena chinyezi mumlengalenga.Mpweya wa haidrojeni wopangidwa ndi poizoni kwa tizilombo, zomwe zimapangitsa kuti tizirombo toyambitsa matenda.Sodium borohydride imagwiritsidwanso ntchito ngati kusintha kwa nthaka chifukwa imachulukitsa pH ya nthaka ndikuwongolera mphamvu yake yosungira madzi.
Ngakhalesodium borohydrideali ndi ntchito zambiri, nkhawa zidakalipo pakupanga ndi kugwiritsa ntchito kwake.Njira yopangira zinthu imaphatikizapo kuchitapo kanthu kwa sodium hydride ndi boron trioxide, yomwe imatulutsa kutentha kwakukulu ndipo imafuna njira zotetezera zoyenera kupewa kuphulika.Kuphatikiza apo, sodium borohydride ikagwiritsidwa ntchito, zopangira zake zimatha kuwononga chilengedwe.Choncho, njira zoyenera zotayira ziyenera kugwiritsidwa ntchito pofuna kupewa kuipitsidwa kwa nthaka ndi madzi.
Powombetsa mkota,sodium borohydridendi gulu losunthika lomwe lapeza ntchito m'mafakitale angapo, kuphatikiza organic synthesis, mphamvu, ndi ulimi.Kuchepetsa kwake kwapadera komanso kuthekera kotulutsa haidrojeni kumapangitsa kuti ikhale chida chofunikira pamachitidwe amankhwala, ukadaulo wama cell cell komanso kuwongolera tizilombo.Komabe, kupanga ndi kugwiritsa ntchito kwake kuyenera kuyang'aniridwa mosamala kuti zitsimikizire chitetezo ndikuchepetsa kuwononga chilengedwe.
