Nhanganyaya
Lithium borohydride inorganic compound ine kemikari formula BH4Li. Icho chinhu chakasimba, kazhinji muchimiro cheupfu hwekristaro chena. Lithium borohydride ine zvinotevera zvivakwa:
1. High hydrogen storage capacity: Lithium borohydride yakanakisa hydrogen kuchengetedza zvinhu, iyo inogona kuchengeta haidrojeni pamwero mukuru.
2. Solubility: Lithium borohydride ine high solubility uye inogona kunyungudutswa mune zvakawanda organic solvents, akadai ether, ethanol uye THF.
3. Kupisa kwakanyanya: Lithium borohydride inogona kupiswa mumhepo uye kusunungura simba guru.
Iko kushandiswa kukuru kwe lithium borohydride ndeiyi:
1. Hydrogen kuchengetedza: Pamusana pehuwandu hwekuchengetedza hydrogen, lithium borohydride inoshandiswa zvakanyanya mumunda wehydrogen simba kuchengetedza uye kusunungura hydrogen.
2. Organic synthesis: Lithium borohydride inogona kushandiswa sechinhu chinodzikisa chehydrogenation reactions muorganic chemical synthesis reactions.
3. Battery teknolojia: Lithium borohydride inogonawo kushandiswa se electrolyte additive ye lithium-ion mabhatiri.
Nzira yekugadzirira ye lithium borohydride inowanzogadzirirwa nekuita kwe lithium metal uye boron trichloride. Iyo chaiyo nzira yekugadzirira ndeyotevera:
1. Kushandisa anhydrous ether sechinhu chinogadziriswa, lithium metal inowedzerwa kune ether mumhepo inert.
2. Wedzera ether solution ye boron trichloride kune lithium metal.
3. Kukurudzira uye nguva dzose kupisa kwekushisa kunoitwa, uye lithium borohydride inonatswa mushure mokunge mhinduro yapera.
1. Lithium borohydride iri nyore kupisa kana ikasangana nemhepo, saka dzivisa kusangana nemoto wakazaruka uye zvinhu zvinopisa zvakanyanya.
2. Lithium borohydride inogumbura ganda nemaziso, uye midziyo yakakodzera yekuzvidzivirira yakadai semagirovhosi nemagogi inofanira kupfekwa pakushanda.
3. Lithium borohydride inofanira kuchengetwa munzvimbo yakaoma, kure nemvura uye mhepo ine unyoro, kudzivirira kuti irege kutora unyoro uye kuora.
Ndokumbira utarise kuti wanzwisisa uye kugona nzira dzakaringana dzekushanda uye ruzivo rwekuchengetedza usati washandisa lithium borohydride. Kana usina kuchengeteka kana usina chokwadi, unofanira kutsvaga hutungamiriri hwenyanzvi.
