Okwu mmalite
Lithium borohydride bụ ihe inorganic nwere usoro kemịkalụ BH4Li. Ọ bụ ihe siri ike, na-adịkarị n'ụdị ntụ ntụ kristal ọcha. Lithium borohydride nwere mmetụta ndị a:
1. Nnukwu nchekwa nchekwa hydrogen: Lithium borohydride bụ ihe nchekwa nchekwa hydrogen dị mma, nke nwere ike ịchekwa hydrogen na oke oke.
2. Solubility: Lithium borohydride nwere nnukwu solubility ma nwee ike ịgbaze n'ọtụtụ ihe mgbaze organic, dị ka ether, ethanol na THF.
3. Nnukwu ọkụ: Lithium borohydride nwere ike ịgba ọkụ na ikuku wee hapụ nnukwu ume.
Isi ojiji nke lithium borohydride bụ:
1. Nchekwa mmiri hydrogen: N'ihi ikike nchekwa hydrogen dị elu, a na-eji lithium borohydride mee ihe n'ọtụtụ ebe na ike hydrogen iji chekwaa ma hapụ hydrogen.
2. Organic njikọ: Lithium borohydride nwere ike iji dị ka a mbenata gị n'ụlọnga maka hydrogenation Jeremaya mere na organic chemical njikọ mmeghachi omume.
3. Teknụzụ batrị: Lithium borohydride nwekwara ike iji dị ka ihe mgbakwunye electrolyte maka batrị lithium-ion.
Usoro nkwadebe nke lithium borohydride na-akwadokarị site na mmeghachi omume nke lithium metal na boron trichloride. Usoro nkwadebe kpọmkwem bụ nke a:
1. Iji ether anhydrous dị ka ihe mgbaze, a na-agbakwunye metal lithium na ether na ikuku inert.
2. Tinye ngwọta ether nke boron trichloride na metal lithium.
3. A na-eme ihe na-akpali akpali na okpomọkụ mgbe niile, na lithium borohydride na-enyocha mgbe emechara mmeghachi omume ahụ.
1. Lithium borohydride dị mfe ọkụ mgbe ị na-akpọtụrụ ikuku, yabụ zere kọntaktị na ọkụ na-emeghe na ihe ndị na-ekpo ọkụ.
2. Lithium borohydride na-akpasu anụ ahụ na anya iwe, yana akụrụngwa nchedo onwe onye kwesịrị ekwesị dịka uwe aka na enyo enyo kwesịrị iyi mgbe ị na-arụ ọrụ.
3. Lithium borohydride kwesịrị ịchekwa n'ebe kpọrọ nkụ, na-adịghị na mmiri na ebe iru mmiri, ka ọ ghara ịmịnye mmiri na ire ere.
Biko hụ na ị ghọtara na marakwa ụzọ ọrụ ziri ezi na ihe ọmụma nchekwa tupu i jiri lithium borohydride. Ọ bụrụ na ị nweghị nchebe ma ọ bụ nwee obi abụọ, ị kwesịrị ịchọ nduzi ọkachamara.
