Selelekela

N-butanol, eo hape e tsejoang e le butanol, ke motsoako oa lintho tse phelang, ke mokelikeli o se nang 'mala o nang le monko o sa tloaelehang oa joala. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea n-butanol:

 

Boleng:

1. Lintho tsa 'mele: Ke mokelikeli o se nang 'mala.

2. Lintho tsa lik'hemik'hale: E ka qhibiliha ka metsing le ka har'a li-solvents, 'me ke motsoako o itekanetseng oa polar. E ka ba oxidized ho butyraldehyde le butyric acid, kapa e ka felloa ke metsi ho etsa butene.

 

Sebelisa:

1. Tšebeliso ea indasteri: Ke motsoako oa bohlokoa 'me o na le mefuta e mengata ea lik'hemik'hale tse sebelisoang indastering ea lik'hemik'hale tse kang litlolo, li-inks le li-detergents.

2. Tšebeliso ea laboratori: E ka sebelisoa e le mokelikeli ho susumetsa helical protheine mene, 'me hangata e sebelisoa litekong tsa biochemical ho etsa hore ho be le liphetoho.

 

Mokhoa:

1. Butylene hydrogenation: Ka mor'a karabelo ea hydrogenation, butene e itšoara ka hydrogen ka pel'a boteng ba catalyst (e kang nickel catalyst) ho fumana n-butanol.

2. Dehydration reaction: butanol e sebetsanoa le li-acids tse matla (tse kang concentrated sulfuric acid) ho hlahisa butene ka karabelo ea dehydration, ebe butene ke hydrogenated ho fumana n-butanol.

 

Lintlha tsa Tšireletseho:

1. Ke mokelikeli o tukang, qoba ho kopana le mohloli oa mollo, 'me u lule hole le malakabe a bulehileng le libaka tse phahameng tsa mocheso.

3. E na le chefo e itseng, qoba ho kopana ka ho toba le letlalo le mahlo, 'me u qobe ho hema mouoane oa eona.

4. Ha e boloka, e lokela ho bolokoa sebakeng se koetsoeng, hole le li-oxidants le mehloli ea mollo, 'me e bolokoe mocheso oa kamore.
