Isingeniso
I-2,4,5-Trifluorobenzoic acid iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: Ayinambala impushana ecwebezelayo emhlophe
- Ukunyibilika: kuncibilika kancane emanzini futhi kuncibilika kuzincibilikisi zemvelo ezifana notshwala, ama-ether nama-ketones
- Izici zamakhemikhali: I-asidi eqinile ehlangana nama-alkali, izinsimbi nezinsimbi ezisebenzayo.
Sebenzisa:
- I-2,4,5-Trifluorobenzoic acid isetshenziswa ngokuyinhloko njengento ebalulekile ephakathi kanye ne-catalyst ku-organic synthesis.
- Kwezinye izimo ezithile, ingasetshenziswa njengomthombo wama-ion e-fluoride futhi ibambe iqhaza ekuphenduleni kwe-fluorination.
- Ingasetshenziswa futhi ekulungiseleleni ezinye izinhlanganisela ze-organofluorine.
Indlela:
Kunezindlela ezihlukahlukene zokulungiselela i-2,4,5-trifluorobenzoic acid, futhi okulandelayo kungenye yezindlela ezivame ukusetshenziswa:
- Sabela i-benzoic acid ne-aluminium trifluoride ukuze uthole i-benzoylaluminium trifluoride.
- Bese, i-benzoyl aluminium trifluoride iphendulwa ngamanzi noma utshwala ukuze i-hydrolyze inikeze u-2,4,5-trifluorobenzoic acid.
Ulwazi Lokuphepha:
- I-2,4,5-Trifluorobenzoic acid iyacasula esikhumbeni nasemahlweni, futhi imishini yokuzivikela efanele iyadingeka lapho uphatha futhi uthintana.
- Endaweni enomswakama, ingahle yehlise izinga futhi ikhiqize amagesi ayingozi, okudingeka asetshenziswe endaweni engenawo umoya.
- Lapho ugcina futhi uthutha, ukuthintana nama-oxidants aqinile, ama-asidi aqinile nezinye izinto kufanele kugwenywe.
- Thola usizo lwezempilo ngokushesha uma udliwe noma uhogelwe.
Izinqubo ezifanele zokusebenza kanye nezinyathelo zokuphepha kufanele zilandelwe lapho kusetshenziswa futhi kusingathwa amakhemikhali, futhi kuhlolwe futhi kulawulwe ngokwesisekelo secala ngalinye.
