Acetoneke seedi se se nang mmala, se tsubehang se nang le monko o matla. E sebelisoa haholo liindastering tse sa tšoaneng, tse kang meriana, petroleum, lik'hemik'hale, joalo-joalo Acetone e ka sebelisoa e le solvent, agent ea ho hloekisa, sekhomaretsi, pente e fokolang, joalo-joalo Sehloohong sena, re tla kenyelletsa tlhahiso ea acetone.
Tlhahiso ea acetone haholo-holo e kenyelletsa mehato e 'meli: mohato oa pele ke ho hlahisa acetone ho tloha ho acetic acid ka ho fokotsa matla,' me mohato oa bobeli ke ho arola le ho hloekisa acetone.
Mohato oa pele, asiti ea acetic e sebelisoa e le lisebelisoa tse tala, 'me catalyst e sebelisoa ho etsa karabelo ea phokotso ea matla ho fumana acetone. Li-catalysts tse sebelisoang hangata ke phofo ea zinki, phofo ea tšepe, joalo-joalo. Mokhoa oa ho itšoara ka tsela e latelang: CH3COOH + H2→CH3COCH3. Mocheso oa karabelo ke 150-250℃, mme khatello ea karabelo ke 1-5 MPa. Phofo ea zinki le phofo ea tšepe li nchafatsoa ka mor'a karabelo 'me li ka sebelisoa khafetsa.
Mohato oa bobeli, motsoako o nang le acetone o arotsoe 'me o hloekisoa. Ho na le mekhoa e mengata ea ho arola le ho hloekisa acetone, joalo ka mokhoa oa distillation, mokhoa oa ho monya, mokhoa oa ho ntša, joalo-joalo Har'a bona, mokhoa oa ho hloekisa ke mokhoa o sebelisoang ka ho fetisisa. Mokhoa ona o sebelisa lintlha tse fapaneng tse belang tsa lintho ho li arola ka distillation. Acetone e na le ntlha e tlase ea ho bela le khatello e phahameng ea mouoane. Ka hona, e ka aroloa ho lintho tse ling ka distillation tlas'a tikoloho e phahameng ea vacuum mocheso o tlase. Joale acetone e arohaneng e romeloa ts'ebetsong e latelang bakeng sa phekolo e eketsehileng.
Ka kakaretso, tlhahiso ea acetone e kenyelletsa mehato e 'meli: phokotso ea catalytic ea acetic acid ho fumana acetone le karohano le tlhoekiso ea acetone. Acetone ke ntho ea bohlokoa ea lik'hemik'hale tse tala ka har'a peterole, lik'hemik'hale, meriana le liindasteri tse ling. E na le mefuta e mengata e fapaneng ea lits'ebetso lefapheng la indasteri le bophelo. Ntle le mekhoa e kaholimo, ho na le mekhoa e meng ea ho etsa acetone, joalo ka mokhoa oa belisoa le mokhoa oa hydrogenation. Mekhoa ena e na le litšoaneleho le melemo ea tsona lits'ebetsong tse fapaneng.
