Isingeniso
I-2,3,4-Trifluorobenzoic acid iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: 2,3,4-trifluorobenzoic acid iyi-crystalline eqinile engenambala.
- Ukunyibilika: Kuncibilika kuzincibilikisi zemvelo njengama-ethers notshwala futhi kuncibilika kancane emanzini.
- Ukuzinza: Izinzile ngokuqhathaniswa ekamelweni lokushisa, kodwa ingancishiswa ngama-oxidants aqinile noma ama-ejenti anciphisa izinga lokushisa eliphezulu.
- Ukuminyana: cishe. 1.63 g/cm³.
Sebenzisa:
- 2,3,4-Trifluorobenzoic acid ivame ukusetshenziswa njengento ebalulekile ephakathi ku-organic synthesis.
- Ingasetshenziswa futhi njengesinqamuleli somlilo embotsheni, odayi, kumapulasitiki, nakumapholymer.
Indlela:
I-2,3,4-Trifluorobenzoic acid ingalungiswa ngezindlela zokwenziwa ezilandelayo:
- I-Benzoic acid isabela nge-trifluoroacetyl chloride ukukhiqiza i-2,3,4-trifluorobenzoyl chloride.
- Bese, i-2,3,4-trifluorobenzoyl chloride iphendulwa ngamanzi ukuze inikeze i-2,3,4-trifluorobenzoic acid.
Ulwazi Lokuphepha:
- Uthuli nomhwamuko we-2,3,4-trifluorobenzoic acid kungase kubangele ukucasuka emehlweni, isikhumba kanye nesistimu yokuphefumula.
- Gqoka izinto zokuzivikela ezifanele njengezingubo zamehlo ezivikelayo, amagilavu, namamaski okuzivikela lapho usebenzisa noma uphatha.
- Uma ifakwe enkomponi, indawo ethintekile kufanele igezwe ngokushesha ngamanzi ahlanzekile futhi ukunakekelwa kwezempilo kufanele kufunelwe ngokushesha ngangokunokwenzeka.
- Lapho ugcina futhi uphatha, izinyathelo zokuphepha ezifanele kanye nezinqubo kufanele zibhekwe, njengokugcina indawo enomoya omuhle kanye nokugwema ukuthintana nezinto ezingahambelani.
