2-Acetylfran ndi organic compound. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 2-acetylfran:
1. Chilengedwe:
- Maonekedwe: 2-acetylfran ndi madzi achikasu otumbululuka.
- Fungo: Kukoma kwa zipatso.
- Kusungunuka: Kusungunuka mu zosungunulira zambiri za organic, monga ethanol, ether, etc.
- Kukhazikika: Kukhazikika ku oxygen ndi kuwala.
2. Kagwiritsidwe:
- Kugwiritsa ntchito mafakitale: 2-acetylfuran ingagwiritsidwe ntchito ngati chigawo cha solvents, lacquerers ndi corrosives.
- Zapakati pamachitidwe amankhwala: Ndiwopakatikati pakuphatikizika kwazinthu zina ndipo nthawi zambiri amagwiritsidwa ntchito popanga organic.
3. Njira:
2-Acetylfran ikhoza kukonzedwa ndi acetylation, ndipo zotsatirazi ndi imodzi mwa njira zodziwika bwino:
- Furan ndi acetic anhydride amagwiritsidwa ntchito pochita.
- Pa kutentha koyenera ndi nthawi yochitapo kanthu, chodyeracho chimayamba kupanga 2-acetylfran.
- Pomaliza, chinthu choyera chimapezedwa ndi distillation ndi njira zoyeretsera.
4. Zambiri Zachitetezo:
- 2-Acetylfran ndi madzi omwe amatha kuyaka ndipo ayenera kusungidwa kutali ndi malawi otseguka komanso magwero a kutentha.
- Pewani kupuma movutikira, kukhudzana ndi khungu ndi maso mukamagwiritsa ntchito, komanso onetsetsani kuti mpweya wabwino ukuyenda bwino.
- Mukakhudza, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupita kuchipatala.
