Hordhac
Lithium borohydride waa unug aan organic ahayn oo leh qaacidada kiimikada BH4Li. Waa walax adag, sida caadiga ah qaabka budada crystalline cad. Lithium borohydride waxay leedahay sifooyinka soo socda:
1. Awoodda kaydinta haydaroojiin sare: Lithium borohydride waa shay kaydinta hydrogen ah oo aad u fiican, kaas oo ku kaydin kara hydrogen marka la eego saamiga sare.
2. Solubility: Lithium borohydride waxa ay leedahay milmayn sare, waxaana lagu milmi karaa dareerayaal badan oo organic ah, sida ether, ethanol iyo THF.
3. Dabool sare: Lithium borohydride waxa lagu gubi karaa hawada oo waxa ay sii dayn kartaa xaddi badan oo tamar ah.
Isticmaalka ugu muhiimsan ee borohydride lithium waa:
1. Kaydinta Hydrogen: Iyada oo ay ugu wacan tahay awoodda kaydinta haydaroojiin ee sarreeya, lithium borohydride waxa si weyn loogu isticmaalaa qaybta tamarta hydrogen si loo kaydiyo loona sii daayo hydrogen.
2. Isku-xidhka Dabiiciga ah: Lithium borohydride waxa loo isticmaali karaa sidii wakiil yaraynta fal-celinta hydrogenation-ka ee fal-celinta kiimikooyinka dabiiciga ah.
3. Tignoolajiyada baytariga: Lithium borohydride waxa kale oo loo isticmaali karaa sidii wax lagu daro electrolyte ee baytariyada lithium-ion.
Habka diyaarinta ee borohydride lithium guud ahaan waxaa lagu diyaariyaa falcelinta birta lithium iyo boron trichloride. Habka diyaarinta gaarka ah waa sida soo socota:
1. Isticmaalka eter-ka anhydrous sida dareere ahaan, birta lithium ayaa lagu daraa eter-ka jawiga aan firfircoonayn.
2. Ku dar dareeraha etherka ee boron trichloride birta lithium.
3. kicinta iyo falcelinta heerkulka joogtada ah ayaa la sameeyaa, lithium borohydride waa la sifeeyaa ka dib marka falcelinta la dhammeeyo.
1. Lithium borohydride waa sahlan tahay in la gubo marka hawada la taabto, markaa iska ilaali taabashada ololka furan iyo walxaha heerkulka sare leh.
2. Lithium borohydride waxay ka xanaajisaa maqaarka iyo indhaha, waana in la xidho qalabka ku habboon ee ilaalinta shakhsi ahaaneed sida galoofyada iyo muraayadaha indhaha marka la shaqaynayo.
3. Lithium borohydride waa in lagu kaydiyaa meel qalalan, kana fog biyaha iyo deegaanka qoyan, si aanay u nuugin qoyaanka iyo qudhunka.
Fadlan hubi inaad fahantay oo aad baratay hababka hawlgalka saxda ah iyo aqoonta badbaadada ka hor inta aanad isticmaalin lithium borohydride. Haddii aadan ammaan ahayn ama shaki ku jiro, waa inaad raadsataa hagitaan xirfadle ah.
