Isingeniso
I-2-Acetylfran iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2-acetylfran:
1. Imvelo:
- Ukubukeka: I-2-acetylfran iwuketshezi olungenambala ukuya kokuphuzi okuphaphathekile.
- Ukuhogela: Ukunambitheka kwesithelo okuyisici.
- Ukunyibilika: Kuncibilika kuzincibilikisi eziningi eziphilayo, njenge-ethanol, i-ether, njll.
- Ukuzinza: Izinzile kumoya-mpilo nokukhanya.
2. Ukusetshenziswa:
- Ukusetshenziswa kwezimboni: I-2-acetylfuran ingasetshenziswa njengengxenye ku-solvents, lacquerers kanye ne-corrosives.
- I-Intermediate ekuphenduleni kwamakhemikhali: Iphakathi ekuhlanganiseni ezinye izinhlanganisela futhi ivame ukusetshenziswa ekuhlanganiseni kwezinto eziphilayo.
3. Indlela:
I-2-Acetylfran ingalungiswa nge-acetylation, futhi okulandelayo kungenye yezindlela ezijwayelekile zokuhlanganisa:
- I-Furan ne-acetic anhydride isetshenziswa ekuphenduleni.
- Ngezinga lokushisa elilungile kanye nesikhathi sokusabela, i-feedstock isabela ukukhiqiza umkhiqizo we-2-acetylfran.
- Okokugcina, umkhiqizo ohlanzekile utholakala ngokuxutshwa nezindlela zokuhlanza.
4. Ulwazi Lokuphepha:
- I-2-Acetylfran iwuketshezi oluvuthayo futhi kufanele igcinwe kude namalangabi avulekile nemithombo yokushisa.
- Gwema ukuhogela, ukuthinta isikhumba namehlo ngesikhathi sokusebenzisa, futhi uqinisekise ukungena komoya okuhle.
- Uma uthintana, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.
