I-sodium borohydride: ikamva lekhemistri eluhlaza kunye nezisombululo ezizinzileyo

Kwilizwe elihlala liguquka lekhemistri, ukufuna ezinye iindlela ezihambelana nokusingqongileyo kuye kwabaluleka.Njengoko ulwazi lwethu malunga nokutshintsha kwemozulu kunye neempembelelo zokusingqongileyo ziqhubeka zikhula, izazinzulu ziye zajika ingqalelo ekufumaneni izisombululo ezizinzileyo.Phakathi kwabo,sodium borohydrideibe lihlakani elinamandla kukhangelo lwekamva eliluhlaza, elizinzileyo.

Yintoni i-sodium borohydride?

I-sodium borohydride, eyaziwa ngokuba yi-NaBH4, yinto esetyenziswa ngokubanzi.Isetyenziswa ikakhulu njenge-ejenti yokunciphisa kwaye ibalulekile kwiindlela ezahlukeneyo zemichiza.Njenge-ejenti yokunciphisa esebenzayo, ekhethiweyo, iipropati zayo ezizodwa zenza ukuba ibe yinxalenye yeenkqubo ezininzi zoshishino.

iKhemistri eluhlaza:

I-chemistry eluhlaza ijolise ukuyila iimveliso zeekhemikhali kunye neenkqubo zokunciphisa impembelelo yazo kwindalo ngaphandle kokuphazamisa ukusebenza kwazo.I-sodium borohydride ihambelana ngokupheleleyo nale migaqo.Ngokwesiko, iikhompawundi ze-organic ziye zasetyenziswa njengee-agent zokunciphisa, ezihlala zikhokelela ekuvelisweni kweemveliso ezinetyhefu.Ukuqaliswa kwe-sodium borohydride njengenye indlela ekhuselekileyo, ehambelana nokusingqongileyo ngundoqo ekuvuleni uhlaza, ukuphendula kweekhemikhali ezizinzileyo.

Izisombululo ezizinzileyo:

Enye yeenzuzo ezibalulekileyo ze-sodium borohydride kukukwazi ukuvelisa igesi yehydrogen xa udibana namanzi okanye eminye imithombo yeproton.Isibaso seHydrojeni sinethemba elikhulu njengomthombo wamandla ohlaziyekayo nococekileyo.Indima ye-sodium borohydride kwimveliso ye-hydrogen inamandla okuguqula ushishino lwamandla, ukunciphisa ukuxhomekeka kwethu kumafutha efosili kunye nokunciphisa ukukhutshwa kwegesi ye-greenhouse.

isicelo:

Ukongeza kwimveliso ye-hydrogen, i-sodium borohydride isetyenziswa ngokubanzi kumashishini ahlukeneyo.Indima yayo kwi-chemistry yamayeza ivumela ukuhlanganiswa kweziyobisi ezisindisa ubomi, ukwandisa ukufikeleleka ngelixa kuncitshiswa umonakalo kwindalo.Ikwasetyenziswa kwiinkqubo zokucocwa kwamanzi amdaka ukuze kususwe ngokufanelekileyo iintsimbi ezinzima eziyingozi kunye nezingcolisi.

I-sodium borohydride yinto ebangela umdla yotshintsho kwihlabathi lekhemistri.Ngobuchule bayo obukhethekileyo bokunciphisa ukukhutshwa kunye neempembelelo ezincinci zokusingqongileyo, inesithembiso esikhulu sekamva elizinzileyo.Ukwamkelwa kwale khompawundi kuvula indlela yeenkqubo zemizi-mveliso eluhlaza, ukuveliswa kwamandla acocekileyo kunye nokuveliswa kwamayeza okukhuselekileyo.Njengoko siqhubeka sihlola amandla e-sodium borohydride, sisondela kwihlabathi apho i-chemistry kunye nokuzinza zihamba kunye, ukudala iplanethi engcono, enempilo kwizizukulwana ezizayo.
