2-Fluoro-4-nitrophenylacetic acid (CAS# 315228-19-4)
| I-Hazard Class | I-IRRITANT |
Isingeniso
i-asidi iyinhlanganisela ye-organic enefomula yamakhemikhali i-C8H6FNO4. Okulandelayo yincazelo yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha lwale nhlanganisela:
Imvelo:
-Ukubukeka: Okuqinile okucwebezelayo okumhlophe kuya kokuphuzi okuphaphathekile
-Indawo yokuncibilika: 103-105 ℃
-Indawo yokubilisa: 337 ℃
-Ukunyibilika: Kuncibilika kancane emanzini, kuncibilika kuzincibilikisi zemvelo ezifana ne-ethanol, i-ether, njll.
Sebenzisa:
-i-asidi ingasetshenziswa njenge-chemical intermediate futhi inezinhlobonhlobo zezicelo ekuhlanganiseni kwezidakamizwa, i-Pesticide Synthesis, i-dayi synthesis neminye imikhakha.
-Ocwaningweni lwezidakamizwa, lungasetshenziswa ukuhlanganisa amanye ama-anti-inflammatory, antibacterial kanye nezinye izinhlanganisela ezisebenzayo.
-Ocwaningweni lwesibulala-zinambuzane, singasetshenziswa ukuhlanganisa ezinye izibulala-zinambuzane, izibulala-zinambuzane, njll.
-Ekuhlanganiseni kodayi, ingasetshenziswa ukuhlanganisa ezinye izingulube namadayi.
Indlela:
Ukulungiswa kwe-asidi kungenziwa ngezinyathelo ezilandelayo:
1. I-2-Fluoro-4-nitrobenzene (2-fluoroo-4-nitrobenzene) iphendulwa nge-bromoacetic acid (bromoacetic acid) ukuze ithole i-2-bromoacetic acid ester (bromoacetic acid ester).
2. Yenza usawoti we-acid bromide nge-ejenti ye-hydrolysis noma uphathe nge-anion exchange resin ukuze uthole i-asidi.
Ulwazi Lokuphepha:
-noma i-asidi iyinhlanganisela yezinto eziphilayo, futhi izinyathelo zokuzivikela ezifanele kufanele zithathwe lapho ziveziwe, njengokugqoka amagilavu okuvikela amakhemikhali, izibuko, njll.
-Kungase kucasule futhi kudle emehlweni, esikhumbeni nasemgudwini wokuphefumula. Gwema ukuthintana ngqo.
-Ngesikhathi sokusetshenziswa nokugcinwa, ukunakekelwa kufanele kuthathwe ukugwema umlilo futhi ugweme ukuthintana nama-oxidants.
-Uma udliwe noma uhogele, funa usizo lwezempilo ngokushesha.
