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.
