Lithium borohydride wani fili ne na inorganic tare da dabarar sinadarai BH4Li. Yana da wani m abu, yawanci a cikin nau'i na fari crystalline foda. Lithium borohydride yana da kaddarorin masu zuwa:
1. Babban ƙarfin ajiyar hydrogen: Lithium borohydride shine kyakkyawan kayan ajiyar hydrogen, wanda zai iya adana hydrogen a babban rabo mai yawa.
2. Solubility: Lithium borohydride yana da babban solubility kuma ana iya narkar da shi a yawancin kaushi na kwayoyin halitta, irin su ether, ethanol da THF.
3. High flammability: Lithium borohydride za a iya ƙone a cikin iska da kuma saki mai yawa adadin kuzari.
Babban amfani da lithium borohydride sune:
1. Ma’ajiyar hydrogen: Saboda yawan iya ajiyar hydrogen, ana amfani da lithium borohydride sosai a fannin makamashin hydrogen don adanawa da sakin hydrogen.
2. Ƙwayoyin halitta: Lithium borohydride za a iya amfani da shi azaman wakili mai ragewa don halayen hydrogenation a cikin halayen haɗin gwiwar kwayoyin halitta.
3. Fasahar batir: Hakanan ana iya amfani da lithium borohydride azaman ƙari ga batir lithium-ion.
Hanyar shiri na lithium borohydride gabaɗaya ana shirya shi ta hanyar ɗaukar ƙarfe na lithium da boron trichloride. Takamammen hanyar shiri shine kamar haka:
1. Yin amfani da ether anhydrous azaman ƙarfi, ana ƙara ƙarfe lithium zuwa ether a cikin yanayi mara kyau.
2. Ƙara ether bayani na boron trichloride zuwa karfe lithium.
3. Ana yin motsa jiki da yawan zafin jiki akai-akai, kuma ana tace lithium borohydride bayan an gama amsawa.
1. Lithium borohydride yana da sauƙin ƙonewa lokacin da yake hulɗa da iska, don haka a guji haɗuwa da bude wuta da abubuwa masu zafi.
2. Lithium borohydride yana cutar da fata da idanu, kuma yakamata a sanya kayan kariya masu dacewa kamar safar hannu da tabarau yayin aiki.
3. Lithium borohydride yakamata a adana shi a busasshen wuri, nesa da ruwa da yanayi mai ɗanɗano, don hana shi ɗaukar danshi da rubewa.
Da fatan za a tabbatar cewa kun fahimci kuma kun ƙware ingantattun hanyoyin aiki da ilimin aminci kafin amfani da lithium borohydride. Idan ba ku da lafiya ko cikin shakka, ya kamata ku nemi jagorar ƙwararru.
