Selelekela

4-Methyl-5-thiazolylethanol hexanoate, e tsejoang hape e le MTBE (Methyl tert-butyl ether), ke mokelikeli o se nang 'mala o nang le monko o khethehileng. Se latelang ke selelekela sa sebopeho sa eona, ts'ebeliso, mokhoa oa tlhahiso le tlhaiso-leseling ea polokeho:

 

Boleng:

E qhibiliha ka har'a metsoako e mengata ea tlhaho e kang alcohols, ethers le ketones, empa e batla e sa qhibilihe ka metsing.

MTBE e na le ts'ebetso e phahameng ea ho thibela ho kokota 'me e ka sebelisoa e le moemeli oa antiknock bakeng sa peterole.

 

Sebelisa:

MTBE e sebelisoa haholo-holo e le tlatsetso bakeng sa peterole ho eketsa khanyetso ea peterole, ho ntlafatsa matla a ho tuka ha peterole le ho fokotsa likhase tse silafatsang moea.

E ka boela ea sebelisoa e le solvent mme e na le lisebelisoa tse itseng tsa lik'hemik'hale tsa lik'hemik'hale, tlhahlobo ea lik'hemik'hale le likarolo tse ling.

 

Mokhoa:

Tokisetso ea MTBE hangata e fumanoa ka karabelo ea condensation ea isopropanol le methanol tlas'a maemo a acidic. Mehato e tobileng e kenyelletsa ho sebetsana le isopropanol ka methanol ka pel'a motsoako oa acid (mohlala, sulfuric acid) ho hlahisa MTBE, e hloekisoang ka ho hlapolla ho fumana sehlahisoa sa ho qetela.

 

Lintlha tsa Tšireletseho:

MTBE ke mokelikeli o tukang o nang le khanya e tlase le mocheso o ikemetseng. E lokela ho sebetsoa sebakeng se nang le moea o motle, hole le malakabe a bulehileng le mehloli ea mocheso.

Ho pepesehela mouoane oa MTBE ka nako e telele ho ka ba le litlamorao tse khopisang mokhoeng oa ho hema, mahlo le letlalo. Lisebelisoa tse loketseng tsa ho itšireletsa tse kang tšireletso ea phefumoloho, likhalase le liatlana tse sireletsang li lokela ho apesoa.

MTBE ke chefo e fokolang, empa ha ea lokela ho nooa kapa ho angoa ke litho tsa ka hare. Haeba motho a ka ja ka phoso kapa a kopana, batla thuso ea bongaka hang-hang.
