Intshayelelo
I-Lithium borohydride yi-inorganic compound kunye ne-chemical formula BH4Li. Yinto eqinileyo, ngokuqhelekileyo ikwimo yomgubo omhlophe wekristale. I-Lithium borohydride inezi mpawu zilandelayo:
1. Umthamo ophezulu wokugcinwa kwe-hydrogen: I-Lithium borohydride yinto egqwesileyo yokugcina i-hydrogen, enokugcina i-hydrogen kumlinganiselo ophezulu wobunzima.
2. Ukunyibilika: I-Lithium borohydride ine-solubility ephezulu kwaye inokunyibilika kwizinto ezininzi ze-organic solvents, ezifana ne-ether, i-ethanol kunye ne-THF.
3. Ukutsha okuphezulu: I-Lithium borohydride inokutshiswa emoyeni kwaye ikhulule umthamo omkhulu wamandla.
Ukusetyenziswa okuphambili kwe-lithium borohydride zezi:
1. Ukugcinwa kwe-Hydrogen: Ngenxa yokugcinwa kwayo okuphezulu kwe-hydrogen, i-lithium borohydride isetyenziswa ngokubanzi kwintsimi yamandla e-hydrogen ukugcina nokukhulula i-hydrogen.
2. I-Organic synthesis: I-Lithium borohydride ingasetyenziswa njenge-arhente yokunciphisa ukuphendula kwe-hydrogenation kwi-organic chemical synthesis reactions.
3. Itekhnoloji yebhetri: I-Lithium borohydride ingasetyenziselwa njengesongezo se-electrolyte kwiibhetri ze-lithium-ion.
Indlela yokulungiselela i-lithium borohydride ilungiswa ngokubanzi ngokuphendula kwe-lithium metal kunye ne-boron trichloride. Indlela ethile yokulungiselela yile ilandelayo:
1. Ukusebenzisa i-ether ye-anhydrous njenge-solvent, i-lithium metal yongezwa kwi-ether kwi-atmospheric inert.
2. Yongeza isisombululo se-ether se-boron trichloride kwintsimbi ye-lithium.
3. Ukufudumala kunye nokufudumala kweqondo lokushisa kuyenziwa, kwaye i-lithium borohydride ihluzwa emva kokuba impendulo igqityiwe.
1. I-Lithium borohydride kulula ukutshisa xa idibene nomoya, ngoko ugweme ukudibanisa nomlilo ovulekileyo kunye nezinto eziphezulu zokushisa.
2. I-Lithium borohydride iyacaphukisa ulusu kunye namehlo, kwaye izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu kunye neeglavu kufuneka zinxitywe xa usebenza.
3. I-Lithium borohydride kufuneka igcinwe kwindawo eyomileyo, kude namanzi kunye nemekobume efumileyo, ukuyithintela ekufunxeni ukufuma kunye nokubola.
Nceda uqinisekise ukuba uyaziqonda kwaye wazi kakuhle iindlela zokusebenza ezichanekileyo kunye nolwazi lokhuseleko phambi kokusebenzisa i-lithium borohydride. Ukuba awukhuselekanga okanye uyathandabuza, kufuneka ufune isikhokelo sobuchule.
