I-acetonelulwelo olungenambala, olucacileyo olunevumba elibukhali nelicaphukisayo. Sisinyibilikisi esinokutsha nesiguquguqukayo kwaye sisetyenziswa kakhulu kushishino, amayeza, nakubomi bemihla ngemihla. Kweli nqaku, siza kuphonononga iindlela zokuchongwa kwe-acetone.

1. Ukuchongwa okubonakalayo

Ukuchongwa okubonakalayo yenye yezona ndlela zilula zokuchonga i-acetone. Iacetone enyulu lulwelo olungenambala noluselubala, ngaphandle kokungcola okanye intlenga. Ukuba ufumanisa ukuba isisombululo siphuzi okanye si-turbid, kubonisa ukuba kukho ukungcola okanye intlenga kwisisombululo.

2. Ukuchongwa kwe-infrared spectrum

Ukuchongwa kwe-infrared spectrum yindlela eqhelekileyo yokuchonga amacandelo e-organic compounds. Iikhompawundi ezahlukeneyo zezinto eziphilayo zinembonakalo eyahlukileyo ye-infrared, enokusetyenziswa njengesiseko sokuchongwa. I-acetone ecocekileyo inophawu lokufunxa kwi-1735 cm-1 kwi-spectrum ye-infrared, eyincopho ye-carbonyl yokwelula i-vibration yeqela le-ketone. Ukuba ezinye iikhompawundi zivela kwisampulu, kuya kubakho utshintsho kwincopho yokufunxa okanye ukubonakala kweencopho ezintsha zokufunxa. Ke ngoko, ukuchongwa kwe-infrared spectrum kungasetyenziselwa ukuchonga i-acetone kunye nokuyahlula kwezinye iikhompawundi.

3. Ukuchongwa kwechromatography yegesi

Ichromatography yegesi yindlela yokwahlula kunye nokuhlalutya iikhompawundi eziguquguqukayo zezinto eziphilayo. Ingasetyenziselwa ukwahlula kunye nokuhlalutya amacandelo emixube enzima kwaye ibone umxholo wecandelo ngalinye. I-acetone ecocekileyo inomlinganiselo othile wechromatographic kwi-chromatogram yegesi, kunye nexesha lokugcinwa malunga nemizuzu eyi-1.8. Ukuba ezinye iikhompawundi zivela kwisampulu, kuya kubakho utshintsho kwixesha lokugcinwa kwe-acetone okanye ukubonakala kweencopho ezintsha zechromatographic. Ngoko ke, i-chromatography yegesi ingasetyenziselwa ukuchonga i-acetone kwaye iyahlula kwezinye iikhompawundi.

4. Ukuchongwa kwe-mass spectrometry

I-Mass spectrometry yindlela yokuchonga iikhompawundi zezinto eziphilayo ngeesampulu ze-ionizing kwindawo ephezulu yokufunxa phantsi kwe-electron beam beam irradiation ene-energy ephezulu, kwaye emva koko ibona iimolekyuli zesampulu ze-ionized nge-mass spectrograph. Ikhompawundi nganye yendalo inobunzima obungafaniyo, obunokusetyenziswa njengesiseko sokuchongwa. I-acetone ecocekileyo inophawu lwe-massspectrum peak kwi-m/z = 43, eyona ncopho ye-ion ye-acetone. Ukuba ezinye iikhompawundi zivela kwisampulu, kuya kubakho utshintsho kwimo ye-massspectrum peak peak okanye ukubonakala kweencopho ezintsha ze-masspectrum. Ke ngoko, i-mass spectrometry ingasetyenziselwa ukuchonga i-acetone kwaye iyahlula kwezinye iikhompawundi.

Isishwankathelo, ukuchongwa okubonakalayo, ukuchongwa kwe-infrared spectrum, ukuchongwa kwe-chromatography yegesi, kunye nokuchongwa kwe-mass spectrometry kungasetyenziselwa ukuchonga i-acetone. Nangona kunjalo, ezi ndlela zifuna izixhobo zobuchwephesha kunye nokusebenza kobugcisa, ngoko kuyacetyiswa ukuba usebenzise amaziko ovavanyo lobuchwephesha ukuze uchonge.
