Lihlahisoa tsa acetone

Acetoneke mokelikeli o se nang 'mala le o bonaletsang, o nang le tšobotsi e matla ea ho fetoha le tatso e khethehileng ea solvent. E sebelisoa haholo indastering, saenseng le thekenoloji, le bophelong ba letsatsi le letsatsi. Sebakeng sa khatiso, hangata acetone e sebelisoa e le solvent ho tlosa sekhomaretsi mochineng oa khatiso, e le hore lihlahisoa tse hatisitsoeng li ka aroloa. Lefapheng la baeloji le meriana, acetone e boetse e le thepa ea bohlokoa e tala bakeng sa motsoako oa metsoako e mengata, joalo ka lihomone tsa steroid le alkaloids. Ntle le moo, acetone e boetse ke ntho e ntle ka ho fetisisa ea ho hloekisa le solvent. E ka qhaqha metsoako e mengata ea lintho tse phelang 'me ea tlosa mafome, mafura le litšila tse ling holim'a likarolo tsa tšepe. Ka hona, acetone e sebelisoa haholo ho lokisa le ho hloekisa mochini le lisebelisoa.

 

Foromo ea molek'hule ea acetone ke CH3COCH3, eo e leng ea mofuta oa metsoako ea ketone. Ntle le acetone, ho boetse ho na le metsoako e meng e mengata ea ketone bophelong ba letsatsi le letsatsi, joalo ka butanone (CH3COCH2CH3), propanone (CH3COCH3) joalo-joalo. Metsoako ena ea ketone e na le litšobotsi tse fapaneng tsa 'mele le lik'hemik'hale, empa kaofela li na le monko o khethehileng le tatso ea solvent.

 

Tlhahiso ea acetone haholo-holo ka ho bola ha acetic acid ka pel'a li-catalysts. Equation ea karabelo e ka hlalosoa e le: CH3COOH → CH3COCH3 + H2O. Ho phaella moo, ho boetse ho na le mekhoa e meng ea ho hlahisa acetone, e kang ho senyeha ha ethylene glycol ka pel'a li-catalysts, hydrogenation ea acetylene, joalo-joalo Acetone ke lisebelisoa tsa letsatsi le letsatsi tsa lik'hemik'hale tse nang le tlhokahalo e phahameng indastering ea lik'hemik'hale. E sebelisoa haholo mafapheng a meriana, baeloji, khatiso, masela, joalo-joalo Ntle le ho sebelisoa e le solvent, e boetse ke lisebelisoa tsa bohlokoa tse tala bakeng sa ho kopanya metsoako e mengata lefapheng la meriana, baeloji le masimo a mang. .

 

Ka kakaretso, acetone ke sesebelisoa se sebetsang haholo sa lik'hemik'hale se nang le menyetla e mengata ea ts'ebeliso. Leha ho le joalo, ka lebaka la ho fetoha ha eona ho phahameng le litšoaneleho tse tukang, e hloka ho tšoaroa ka hloko tlhahiso le tšebeliso ho qoba likotsi.
