Aluminium borohydride ke motsoako oa inorganic. E na le litšobotsi tse latelang:
1. Lintho tsa 'mele: Aluminium borohydride ke ntho e tiileng e se nang 'mala, hangata e le phofo. Ha e tsitsisehe haholo mochesong oa kamore 'me e tlameha ho bolokoa le ho sebetsoa ka mocheso o tlase le tikoloho ea khase e sa sebetseng.
2. Lintho tsa lik'hemik'hale: Aluminium borohydride e ka itšoara ka li-acids, joala, ketone le metsoako e meng ho etsa lihlahisoa tse lumellanang. Karabelo e mabifi e etsahala ka metsing ho hlahisa hydrogen le aluminium acid hydride.
Tšebeliso ea mantlha ea aluminium borohydride e kenyelletsa:
1. Joaloka moemeli oa ho fokotsa: Aluminium borohydride e na le thepa e matla ea ho fokotsa, 'me e atisa ho sebelisoa e le ho fokotsa lintho tse entsoeng ka tlhaho. E ka fokotsa metsoako e kang aldehydes, ketones, joalo-joalo, ho ea ho li-alcohol tse tsamaellanang.
2. Tšebeliso ea lipatlisiso tsa mahlale: Aluminium borohydride e na le bohlokoa ba lipatlisiso tšimong ea organic synthesis le catalysis, 'me e ka sebelisoa ho kopanya metsoako e mecha ea tlhaho le ho susumetsa maikutlo.
Ka kakaretso ho na le mekhoa e 'meli ea ho lokisetsa aluminium borohydride:
1. Karabelo pakeng tsa aluminium hydroxide le trimethylboron: trimethylboron e qhibiliha ka tharollo ea ethanol ea aluminium hydroxide, khase ea hydrogen e hlahisoa ho fumana aluminium borohydride.
2. Karabelo ea alumina le dimethylborohydride: sodium dimethylborohydride le alumina li futhumetse 'me li itšoara ho fumana aluminium borohydride.
Ha u sebelisa aluminium borohydride, lintlha tse latelang tsa polokeho li lokela ho hlokomeloa:
1. Aluminium borohydride e na le reducibility e matla, 'me e tla itšoara ka mabifi ha e kopana le metsi, asiti le lintho tse ling, e hlahisang khase e tukang le likhase tse chefo. Likhalase tse sireletsang, liatlana le liaparo tse sireletsang li tlameha ho apesoa nakong ea ts'ebetso.
2. Aluminium borohydride e lokela ho bolokoa sebakeng se omileng, se tiisitsoeng le se lefifi, hole le mollo le thepa e tukang.
3. Ho hlaseloa ha pampiri ea ho hema kapa letlalo ho ka baka kotsi e tebileng 'me e tlameha ho qojoa bakeng sa ho hema le ho kopana. Haeba ho ka etsahala hore u kopane ka phoso, hlatsoa hang-hang ka metsi a mangata 'me u batle ngaka.
