I-acetoneiwuketshezi olungenambala, olusobala olunephunga elibukhali nelicasulayo. Kuyi-solvent ephilayo evuthayo futhi eguquguqukayo futhi isetshenziswa kakhulu embonini, kwezokwelapha, nasempilweni yansuku zonke. Kulesi sihloko, sizohlola izindlela zokuhlonza i-acetone.

1. Ukuhlonza okubonakalayo

Ukuhlonza okubonakalayo kungenye yezindlela ezilula zokuhlonza i-acetone. I-acetone ehlanzekile inguketshezi olungenambala futhi olusobala, olungenakho ukungcola noma inzika. Uma uthola ukuthi isixazululo siphuzi noma sine-turbid, kubonisa ukuthi kukhona ukungcola noma i-sediment esixazululweni.

2. Ukuhlonza i-infrared spectrum

Ukuhlonza i-infrared spectrum kuyindlela evamile yokuhlonza izingxenye zenhlanganisela yezinto eziphilayo. Izinhlobonhlobo ze-organic compounds zine-spectra ye-infrared ehlukene, engasetshenziswa njengesisekelo sokuhlonza. I-acetone emsulwa inesici sokumuncwa esiqongweni esingu-1735 cm-1 ku-spectrum ye-infrared, okuyinani eliphakeme lokudlidliza elinwebekayo le-carbonyl leqembu le-ketone. Uma ezinye izinhlanganisela zivela kusampula, kuzoba nezinguquko endaweni ephakeme kakhulu yokumuncwa noma ukubonakala kweziqongo ezintsha zokumunca. Ngakho-ke, ukuhlonza i-infrared spectrum kungasetshenziswa ukukhomba i-acetone futhi iyihlukanise kwezinye izinhlanganisela.

3. Ukuhlonza i-chromatography yegesi

I-gas chromatography iyindlela yokuhlukanisa nokuhlaziya izinhlanganisela zezinto eziphilayo eziguquguqukayo. Ingasetshenziselwa ukuhlukanisa nokuhlaziya izingxenye zezingxube eziyinkimbinkimbi futhi ithole okuqukethwe kwengxenye ngayinye. I-acetone emsulwa inenani elithile eliphakeme le-chromatographic ku-chromatogram yegesi, nesikhathi sokugcina cishe imizuzu eyi-1.8. Uma ezinye izinhlanganisela zivela kusampula, kuzoba nezinguquko esikhathini sokugcinwa kwe-acetone noma ukubonakala kweziqongo ezintsha zechromatographic. Ngakho-ke, i-chromatography yegesi ingasetshenziswa ukukhomba i-acetone futhi iyihlukanise kwezinye izinhlanganisela.

4. Ukuhlonza i-mass spectrometry

I-Mass spectrometry iyindlela yokuhlonza inhlanganisela yezinto eziphilayo ngokufaka amasampula e-ionizing endaweni ye-vacuum ephezulu ngaphansi kwe-radiation ye-electron beam ephezulu yamandla, bese ithola amasampula e-ionized molecule nge-mass spectrograph. Inhlanganisela ngayinye ye-organic ine-mass spectrum eyingqayizivele, engasetshenziswa njengesisekelo sokuhlonza. I-acetone ehlanzekile inesici esiphezulu se-mass spectrum ku-m/z=43, okuyisiqongo se-ion yamangqamuzana e-acetone. Uma ezinye izinhlanganisela zivela kusampula, kuzoba nezinguquko endaweni ephakeme ye-mass spectrum noma ukubonakala kweziqongo ze-mass spectrum entsha. Ngakho-ke, i-mass spectrometry ingasetshenziswa ukukhomba i-acetone futhi iyihlukanise kwezinye izinhlanganisela.

Kafushane, ukuhlonza okubonakalayo, ukuhlonza i-infrared spectrum, ukuhlonza i-gas chromatography, nokuhlonza i-mass spectrometry kungasetshenziswa ukukhomba i-acetone. Kodwa-ke, lezi zindlela zidinga amathuluzi ochwepheshe nokusebenza kobuchwepheshe, ngakho-ke kunconywa ukuthi usebenzise izikhungo zokuhlola eziqeqeshiwe ukuze uhlonzwe.
