Intshayelelo
I-2-Acetylfran yi-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-2-acetylfran:
1. Indalo:
- Imbonakalo: 2-acetylfran lulwelo olungenambala ukuya kumthubi.
- Ivumba: Uphawu lwencasa yeziqhamo.
-Ukunyibilika: Inyibilika kuninzi lwezinyibilikisi zendalo, njenge-ethanol, i-ether, njl.
- Uzinzo: Uzinzile kwioksijini kunye nokukhanya.
2. Ukusetyenziswa:
- Ukusetyenziswa kwamashishini: I-2-acetylfuran ingasetyenziselwa njengenxalenye kwi-solvents, i-lacquerers kunye ne-corrosives.
- I-Intermediates kwi-chemical reactions: Yindawo ephakathi kwi-synthesis yezinye iikhompawundi kwaye isoloko isetyenziswa kwi-organic synthesis.
3. Indlela:
I-2-Acetylfran inokulungiswa nge-acetylation, kwaye oku kulandelayo yenye yeendlela eziqhelekileyo zokudibanisa:
- I-Furan kunye ne-acetic anhydride isetyenziswa kwi-reaction.
- Kwiqondo lokushisa elifanelekileyo kunye nexesha lokuphendula, i-feedstock isabela ukuvelisa imveliso ye-2-acetylfran.
- Ekugqibeleni, imveliso ecocekileyo ifunyenwe nge-distillation kunye neendlela zokucoca.
4. Ulwazi ngoKhuseleko:
- 2-Acetylfran lulwelo olunokutsha kwaye kufuneka lugcinwe kude namadangatye avulekileyo kunye nemithombo yobushushu.
- Kuphephe ukuphefumla, ukudibana nesikhumba kunye namehlo ngexesha lokusetyenziswa, kwaye uqinisekise ukungena komoya okulungileyo.
- Kwimeko yoqhagamshelwano, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango.
