Isingeniso
I-2-Chloro-4-fluorobenzoic acid iyinhlanganisela ephilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2-chloro-4-fluorobenzoic acid:
Ikhwalithi:
- Ukubukeka: I-2-Chloro-4-fluorobenzoic acid iyikristale eqinile emhlophe.
- Ukunyibilika: Inokuncibilika okuphansi emanzini, kodwa inokuncibilika okuhle kuzincibilikisi zemvelo (isb., i-ethanol, i-acetone).
- Ukuzinza: Kuyinhlanganisela ezinzile, kodwa ukuthintana nama-oxidants aqinile nama-asidi kufanele kugwenywe.
Sebenzisa:
- Iziphakathi zamakhemikhali: I-2-chloro-4-fluorobenzoic acid ingasetshenziswa njengezixhumanisi zamakhemikhali ku-organic synthesis.
- I-Surfactant: Ingasetshenziswa njengempahla eluhlaza yama-surfactants futhi inomsebenzi omuhle wangaphezulu kanye nezindawo zokuhlakazeka.
- Izinto ezikwazi ukuthwebula izithombe: I-2-chloro-4-fluorobenzoic acid ingasetshenziswa ukulungisa izinto ezithatha izithombe, njengezinamatheliso ezelapha ukukhanya.
Indlela:
I-2-Chloro-4-fluorobenzoic acid ingatholwa ngokusabela kwe-fluorochloro-substitution ye-p-dichlorobenzoic acid noma i-difluorobenzoic acid. Izindlela eziqondile zokulungiselela zingase zihlanganise i-fluorochloro-substitution, i-fluorination noma okunye ukusabela okufanele esikhundleni.
Ulwazi Lokuphepha:
- Ubuthi: I-2-chloro-4-fluorobenzoic acid iyinhlanganisela ye-organofluorine, engenabuthi obuncane kunezinhlanganisela ezijwayelekile ze-organofluorine. Nokho, kufanele kuqikelelwe ukugwema ukuhogela umoya noma ukuthintana.
- Ukucasuka: Kungabangela ukucasuka kwamehlo, isikhumba kanye nendlela yokuphefumula futhi kufanele kugezwe ngokushesha ngemva kokuxhumana.
- Izinto zokucisha umlilo: Emlilweni, ukucisha kufanele kwenziwe ngesicisha-mlilo esifanele njenge-carbon dioxide, igwebu noma impushana eyomile, kugwenywe ukusetshenziswa kwamanzi ukuze kucishwe umlilo njengoba kune-solubility encane emanzini.
- Isitoreji: I-2-Chloro-4-fluorobenzoic acid kufanele igcinwe endaweni eyomile, enomoya omuhle, kude nomlilo kanye nama-oxidants aqinile.
