Sodium borohydridengumgubo we-crystalline emhlophe ngefomula yekhemicamicamicane Nabh4. Yiarhente enamandla yokuncitshiswa esetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yepropathi yayo eyahlukileyo kunye nokungasebenzi kakuhle. Eli nqaku alikho kuphela kwi-chemistry ye-organic, kodwa idlala indima ebalulekileyo kwiinkqubo zemveliso, usetyenziso lwendalo esingqongileyo, kunye neendawo ezenzakalisayo. Kwezi bhlog, siya kuphonononga indawo yokusetyenziswa kwezilwanyana kwi-sodium borohydride kwaye ibaluleke kakhulu kwimimandla eyahlukeneyo.
Ukunciphisa iiarhente kwi-chemistry ye-organic
Enye yezicelo eziphambili zesodium borohydride yindima yayo njengearhente yokunciphisa i-organic chemistry. Kuyimpumelelo ngakumbi ekunciphiseni i-AldeHYSE kunye neeKetos kwi-collopt ehambelana. Le mpendulo ibalulekile kwi-synthesis yoluhlu olubanzi lwezinto eziphilayo, ezenza i-sodium borohydride i-prowrications ephambili kwilabhoratri kunye noseto lwemizi-mveliso. Ukukwazi kwayo ukukhetha ukunciphisa amaqela asebenza imisebenzi kwenza ukuba oochwephesha basebenzela iimolethi ezintsonkothileyo ngokuchaneka, kusenza sisixhobo esibalulekileyo kwicandelo lezinto eziphilayo.
Izithako eziphambili zeziyobisi
Sodium borohydrideikwasetyenziswa kumzi-mveliso wamachiza, ngakumbi njenge-hydroning therment ye-dihydrostreptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptoptopycin, i-antibiotic esetyenziselwa ukunyanga isifo sephepha. Inkqubo yokuncitshiswa ikhuthazwe yi-sodium borohydride ibaluleke kakhulu ekuvelisweni kwesi siyobisi sibalulekileyo. Ukongeza, isodium borohydride inokusetyenziswa njengendawo ephakathi kwimveliso ye-PBH (POLORORORYDDRRNDRRNDRENDREDDRENDER) kwaye isetyenziswa kwiinkqubo ezahlukeneyo zekhemikhali. Indima yayo kumayeza ibalaselisa ukubaluleka kwe-sorohydride yokuphuhliswa kwamachiza okusindisa ubomi.
Ukuphucula inkqubo yokwenza
Kwimveliso,sodium borohydrideisetyenziswa njengearhente yokubetha iplastiki. Esi sicelo sibaluleke ngokukhethekileyo ekuvelisweni kwezinto zeplasitiki ezikhanyayo kunye neplastiki. Ngokongeza i-sodium borohydride ngexesha lokwenza imveliso, inkampani inokwenza i-foam engabomeleleyo kuphela kodwa ikwanazo iipropathi eziguquguqukayo. Ukuvela okuvela kwimveliso yeemveliso ezivela kwizinto zokupakisha ukuya kwiindawo ezizenzekelayo.
Isicelo sendalo esingqongileyo
Sodium borohydrideUsebenzisa ngaphandle kwezicelo zemveli zemveli. Ikwadlala indima ebalulekileyo kulawulo lwendalo. Isicelo esinye esibonakalayo sinjengearhente yonyango lwamanzi amdaka amanzi amdaka. I-Mercury yintsimbi enetyhefu enetyhefu ebeka umngcipheko kwindalo kunye nempilo. I-sodium borohydride inokunciphisa ngokufanelekileyo ii-Ion zeMercur kumhlaba otshintshwayo kwaye uziguqule zibe ziifom eziyingozi. Esi sicelo sibalulekile kumashishini ajongana nongcoliseko lwensimbi enzima, encedisa ukunciphisa ukungcoliseka kokusingqongileyo nokukhusela imigaqo-nkqubo yendalo.
Indima kwiShishini lePhepha
Umzi mveliso wephepha ukwamkela izibonelelo ze-sodium borohydride. Isetyenziselwa inkqubo yonyawo ukunceda ukunciphisa umbala we-pulp yenkuni, kukhokelela kwimveliso eqaqambileyo, yephepha elimhlophe. Esi sicelo asiphumi nje umgangatho wemveliso yokugqibela kodwa ikwanegalelo kwiindlela ezizinzileyo ngokunciphisa isidingo seekhemikhali ezinobunzima kwinkqubo yokuqhushumba.
Sodium borohydrideyingxowa ephawulekayo ngoluhlu olubanzi lwezicelo kumashishini ahlukeneyo. Kwindima yayo njengearhente yokunciphisa i-orgastric chemistry kwizicelo kwiindawo zamayeza, ukuvelisa, ulawulo lwendalo kunye ne-Depermaghtdride iqinisekisiwe ukuba sisixhobo esibalulekileyo kwiSayensi yanamhlanje. Njengoko uphando luyaqhubeka nokufumana ukusetyenziswa okutsha kwezi lube ziguquguqukayo, ukubaluleka kwayo kunokwenzeka ukuba kunyuke, kusenza umdlali ophambili ekuqinisekiseni izinto ezintsha kunye nokuzinza. Nokuba ungumchweli, umvelisi, okanye ubume bendalo, ukuqonda izicelo ezininzi ze-sodium boronehride kunokubonelela ngokuqonda okuxabisekileyo kwimpembelelo yayo kwihlabathi lethu.
