Acetoneke seedi se senang mmala, se bonaletsang se nang le monko o bohale le o hlabang.Ke sehlapolli sa lintho tse phelang se tukang mollo 'me se sebelisoa haholo indastering, meriana le bophelong ba letsatsi le letsatsi.Sehloohong sena, re tla hlahloba mekhoa ea ho khetholla acetone.

1. Boitsebiso bo bonahalang

Ho tsebahatsa ka pono ke e 'ngoe ea mekhoa e bonolo ka ho fetisisa ea ho khetholla acetone.Acetone e hloekileng ke mokelikeli o se nang 'mala le o bonaletsang, o se nang litšila kapa litšila.Haeba u fumana hore tharollo ke mosehla kapa turbid, e bontša hore ho na le litšila kapa sediment ka tharollo.

2. Boitsebiso ba mahlaseli a infrared

Infrared spectrum identification ke mokhoa o tloaelehileng oa ho khetholla likarolo tsa metsoako ea tlhaho.Metsoako e fapaneng ea manyolo e na le ponahalo e fapaneng ea infrared, e ka sebelisoang e le motheo oa ho tsebahatsa.Acetone e hloekileng e na le tlhōrō ea ho monya ho 1735 cm-1 ho infrared spectrum, e leng tlhōrō ea ho sisinyeha ea carbonyl ea sehlopha sa ketone.Haeba metsoako e meng e hlaha sampoleng, ho tla ba le liphetoho boemong ba tlhoro ea ho monya kapa ponahalo ea litlhoro tse ncha tsa ho monya.Ka hona, infrared spectrum identification e ka sebelisoa ho khetholla acetone le ho e khetholla ho metsoako e meng.

3. Boitsebiso ba chromatography ea khase

Khase chromatography ke mokhoa oa ho arola le ho sekaseka metsoako ea lintho tse phelang.E ka sebelisoa ho arola le ho sekaseka likarolo tsa metsoako e rarahaneng le ho lemoha litaba tsa karolo ka 'ngoe.Acetone e hloekileng e na le tlhoro e ikhethileng ea chromatographic ho chromatogram ea khase, ka nako ea ho boloka e ka bang metsotso e 1.8.Haeba metsoako e meng e hlaha sampuling, ho tla ba le liphetoho nakong ea ho boloka acetone kapa ponahalo ea litlhōrō tse ncha tsa chromatographic.Ka hona, chromatography ea khase e ka sebelisoa ho khetholla acetone le ho e khetholla ho metsoako e meng.

4. Boitsebiso ba spectrometry ea boima

Mass spectrometry ke mokhoa oa ho khetholla metsoako ea lintho tse phelang ka lisampole tsa ionizing sebakeng se phahameng sa vacuum tlas'a mahlaseli a matla a matla a elektronike, ebe o lemoha limolek'hule tsa ionized ka mass spectrograph.Motsoako o mong le o mong oa tlhaho o na le bongata bo ikhethang, bo ka sebelisoang e le motheo oa ho tsebahatsa.Acetone e hloekileng e na le tlhōrō ea boima ba 'mele ho m/z=43, e leng tlhoro ea ion ea molek'hule ea acetone.Haeba metsoako e meng e hlaha sampuling, ho tla ba le liphetoho boemong ba tlhōrō ea mahlahahlaha a mangata kapa ponahalo ea litlhōrō tse ncha tsa spectrum.Ka hona, spectrometry ea boima e ka sebelisoa ho khetholla acetone le ho e khetholla ho metsoako e meng.

Ka bokhuts'oane, boitsebahatso ba pono, boitsebahatso ba sebono sa infrared, boitsebahatso ba chromatography ea khase, le boitsebahatso ba boima ba spectrometry bo ka sebelisoa ho khetholla acetone.Leha ho le joalo, mekhoa ena e hloka lisebelisoa tsa profeshenale le ts'ebetso ea tekheniki, ka hona ho khothaletsoa hore o sebelise litsi tsa tlhahlobo ea litsebi bakeng sa boitsebahatso.
