Acetonemai launi ne mai launi, ruwa mai narkewa wanda aka yi amfani dashi sosai a masana'antu da rayuwar yau da kullun. Wani nau'in jikin mutum ne tare da tsarin kwayar halittar C3h6o. Acetone abu ne mai wuta tare da tafasasshen yanayi na 56.11°C da melting m na -94.99°C. Yana da mai ƙanshi mai haushi kuma yana da m. Yana da narkewa cikin ruwa, eth, da barasa, amma ba cikin ruwa ba. Abubuwan da ke da amfani ne na albarkatun ƙasa a cikin masana'antar sunadarai, wanda za'a iya amfani dashi don samar da mahadi iri-iri, kuma ana amfani dashi azaman sauran ƙarfi, tsabtace, da sauransu.

Menene kayan masarufi na acetone? Kodayake ba a sanyayar ƙwayoyin rigakafi ne mai tsabta ba, tsarin samarwa ya shafi yawancin halayen. Bari mu bincika abun da ake ciki na acetone daga tsarin samarwa.

Da farko dai, menene hanyoyin yin acetone? Akwai hanyoyi da yawa don samar da acetone, daga cikinsu mafi yawanci shine oxidation na catalytic na propylene. Wannan tsari yana amfani da iska a matsayin oxidant, kuma yana amfani da mai kara kuzari don sauya propylene zuwa cikin acetone. Daidaitawa daidai yake kamar haka:

Ch3ch = ch2 + 3 / 2o2→Ch3coch3 + h2o2

Contalyst da aka yi amfani da shi a cikin wannan amsawar yawanci ana tallafawa iri-iri na titanium dioxide a kan mai ɗaukar ciki kamarγ-Ang2O3. Wannan nau'in mai kara kuzari yana da aiki mai kyau da kuma buƙatar canjin provylene zuwa acetone. Bugu da kari, wasu hanyoyin sun hada da samar da acetone ta dileydrogenation na isopropannol, da samar da acetone ta hydrolysis na Acrolein, da sauransu.

Don haka menene sinadarai suke yin acetone? A cikin tsarin samar da acetone, ana amfani da propylene azaman albarkatun kasa, da kuma ana amfani da iska a matsayin outidant. Mai kara kuzari da aka yi amfani da shi a cikin wannan tsari yawanci titanid dioxide ya tallafawaγ-Ang2O3. Bugu da kari, domin samun tsarkakakkiyar acetone, bayan amsawar rabuwa da tsattsauran ra'ayi kamar distilation da reshe ana buƙatar cire sauran ƙazanta a cikin samfurin dauki.

Bugu da kari, domin samun babban-tsarkakakke-tsarkaka kamar yadda ake tsarkakewa kamar distilation da kuma ƙara yawanci ana buƙatar cire wasu impurities. In addition, in order to protect the environment and human health, appropriate treatment measures should be taken in the production process to reduce pollution and emissions.

A takaice, samar da samar da acetone ya shafi abubuwa da yawa da matakai, amma babban albarkatun kasa da oxidant sune propylene da iska bi da bi. Bugu da kari, Titanium Dioxide ya goyi bayanγ-Al2o3 ana amfani da shi azaman mai kara kuzari don inganta tsarin binciken. A ƙarshe, bayan matakan rabuwa da tsattsagewa kamar distilation da kuma gyara, za a iya samun babban-tsarkakakkiyar acetone don amfani dashi a aikace-aikace daban-daban.
