Zizindikiro Zowopsa | R14/15 - R23/24/25 – Poizoni pokoka mpweya, kukhudzana ndi khungu komanso kummeza. R34 - Imayambitsa kuyaka R20/21/22 - Zowopsa pokoka mpweya, kukhudzana ndi khungu komanso kumeza. R11 - Yoyaka Kwambiri R40 - Umboni wochepa wa zotsatira za carcinogenic R36/37/38 - Zokwiyitsa maso, kupuma komanso khungu. R19 - Itha kupanga ma peroxides ophulika R67 - Nthunzi imatha kuyambitsa kugona komanso chizungulire R66 - Kuwonekera mobwerezabwereza kungayambitse khungu kuuma kapena kusweka R22 - Zowopsa ngati zitamezedwa R12 - Yoyaka Kwambiri |
Kufotokozera Zachitetezo | S26 - Mukakhudza maso, yambani nthawi yomweyo ndi madzi ambiri ndikupempha uphungu wachipatala. S36/37/39 - Valani zovala zodzitchinjiriza zoyenera, magolovesi ndi chitetezo chamaso / kumaso. S43 - Pakagwiritsidwa ntchito moto ... (pamatsatira mtundu wa zida zozimitsa moto zomwe zigwiritsidwe ntchito.) S45 - Pakachitika ngozi kapena ngati simukumva bwino, funsani upangiri wachipatala nthawi yomweyo (onetsani chizindikirocho ngati kuli kotheka.) S36/37 - Valani zovala zoyenera zodzitchinjiriza ndi magolovesi. S16 - Khalani kutali ndi magwero oyatsira. |

Lithium borohydride ndi mankhwala opangidwa ndi mankhwala BH4Li. Ndi chinthu cholimba, nthawi zambiri chimakhala ngati ufa woyera wa crystalline. Lithium borohydride ili ndi zotsatirazi:
1. Kuchuluka kwa hydrogen yosungirako: Lithium borohydride ndi chinthu chabwino kwambiri chosungiramo haidrojeni, chomwe chimatha kusunga haidrojeni pamlingo waukulu.
2. Kusungunuka: Lithium borohydride imakhala ndi kusungunuka kwakukulu ndipo imatha kusungunuka muzitsulo zambiri za organic, monga ether, ethanol ndi THF.
3. Kutentha kwakukulu: Lithium borohydride ikhoza kutenthedwa mumlengalenga ndikutulutsa mphamvu zambiri.
Ntchito zazikulu za lithiamu borohydride ndi:
1. Kusungirako kwa haidrojeni: Chifukwa cha mphamvu yake yosungiramo haidrojeni, lithiamu borohydride imagwiritsidwa ntchito kwambiri m'munda wa mphamvu ya hydrogen kusunga ndi kumasula haidrojeni.
2. Organic kaphatikizidwe: Lithium borohydride angagwiritsidwe ntchito ngati kuchepetsa wothandizila kwa hydrogenation zimachitikira organic mankhwala synthesis zimachitikira.
3. Ukadaulo wa batri: Lithium borohydride itha kugwiritsidwanso ntchito ngati chowonjezera cha electrolyte pamabatire a lithiamu-ion.
Njira yokonzekera lithiamu borohydride nthawi zambiri imakonzedwa ndi zomwe lithiamu chitsulo ndi boron trichloride. Njira yeniyeni yokonzekera ndi iyi:
1. Pogwiritsa ntchito ether anhydrous monga zosungunulira, zitsulo za lithiamu zimawonjezeredwa ku ether mumlengalenga.
2. Onjezani yankho la ether la boron trichloride ku zitsulo za lithiamu.
3. Kulimbikitsana kwa kutentha kosalekeza kumachitika, ndipo lithiamu borohydride imasefedwa pambuyo pomaliza.
1. Lithium borohydride ndiyosavuta kuyaka mukakumana ndi mpweya, choncho pewani kukhudzana ndi malawi otseguka komanso zinthu zotentha kwambiri.
2. Lithium borohydride imakwiyitsa khungu ndi maso, ndipo zida zoyenera zodzitetezera monga magolovesi ndi magalasi ziyenera kuvalidwa pochita opaleshoni.
3. Lithium borohydride iyenera kusungidwa pamalo ouma, kutali ndi madzi ndi chinyezi, kuti isatenge chinyezi ndikuwola.
Chonde onetsetsani kuti mwamvetsetsa ndikuzindikira njira zoyendetsera ntchito ndi chidziwitso chachitetezo musanagwiritse ntchito lithiamu borohydride. Ngati simuli otetezeka kapena mukukayika, muyenera kufunsa akatswiri.
