Taw qhia
Lithium borohydride yog ib qho inorganic compound nrog cov tshuaj formula BH4Li. Nws yog ib yam khoom, feem ntau nyob rau hauv daim ntawv ntawm ib tug dawb crystalline hmoov. Lithium borohydride muaj cov khoom hauv qab no:
1. High hydrogen cia muaj peev xwm: Lithium borohydride yog cov khoom siv hydrogen zoo heev, uas tuaj yeem khaws cov hydrogen ntawm qhov sib piv loj.
2. Solubility: Lithium borohydride muaj siab solubility thiab yuav yaj nyob rau hauv ntau cov organic solvents, xws li ether, ethanol thiab THF.
3. High flammability: Lithium borohydride tuaj yeem hlawv hauv huab cua thiab tso tawm ntau lub zog.
Kev siv tseem ceeb ntawm lithium borohydride yog:
1. Hydrogen cia: Vim nws lub peev xwm hydrogen siab, lithium borohydride tau siv dav hauv kev siv hluav taws xob hydrogen los khaws thiab tso tawm hydrogen.
2. Organic synthesis: Lithium borohydride tuaj yeem siv los ua tus neeg sawv cev txo qis rau cov tshuaj hydrogenation hauv cov tshuaj lom neeg cov tshuaj synthesis.
3. Roj teeb tshuab: Lithium borohydride kuj tuaj yeem siv los ua cov khoom siv hluav taws xob ntxiv rau cov roj teeb lithium-ion.
Txoj kev npaj ntawm lithium borohydride feem ntau yog npaj los ntawm cov tshuaj tiv thaiv ntawm lithium hlau thiab boron trichloride. Txoj kev npaj tshwj xeeb yog raws li hauv qab no:
1. Siv anhydrous ether ua cov kuab tshuaj, lithium hlau yog ntxiv rau ether nyob rau hauv ib qho chaw inert.
2. Ntxiv cov tshuaj ether ntawm boron trichloride rau lithium hlau.
3. Stirring thiab qhov kub thiab txias cov tshuaj tiv thaiv yog nqa tawm, thiab lithium borohydride yog lim tom qab cov tshuaj tiv thaiv tiav.
1. Lithium borohydride yog ib qho yooj yim rau hlawv thaum nyob rau hauv kev sib cuag nrog huab cua, yog li tsis txhob sib cuag nrog qhib nplaim taws thiab kub-kub tshuaj.
2. Lithium borohydride ua rau khaus tawv nqaij thiab qhov muag, thiab cov khoom siv tiv thaiv tus kheej tsim nyog xws li hnab looj tes thiab tsom iav yuav tsum hnav thaum ua haujlwm.
3. Lithium borohydride yuav tsum tau muab cia rau hauv qhov chaw qhuav, deb ntawm dej thiab qhov chaw ntub dej, tiv thaiv nws los ntawm absorbing noo noo thiab decomposing.
Thov xyuas kom meej tias koj tau nkag siab thiab paub txog cov kev ua haujlwm raug thiab kev paub txog kev nyab xeeb ua ntej siv lithium borohydride. Yog tias koj tsis muaj kev nyab xeeb lossis tsis ntseeg, koj yuav tsum nrhiav kev qhia ua haujlwm.
