2-Chloro-3-fluoro-5-methylpyridine (CAS# 34552-15-3)
| Izimpawu Eziyingozi | Xi - Irritant |
| I-Hazard Class | I-IRRITANT |
Isingeniso
Kuyinhlanganisela yemvelo enefomula yamakhemikhali ye-C6H5ClFN. Okulandelayo incazelo yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwenhlanganisela:
Imvelo:
-Ukubukeka: Iwuketshezi olungenambala ukuya kokuphuzi.
-Indawo yokubilisa: cishe ku-126-127°C.
-Ukuminyana: mayelana ne-1.36g/cm³.
-I-Solubility: Incibilika kuzincibilikisi eziningi eziphilayo, njenge-ethanol, i-ether ne-dimethylformamide.
Sebenzisa:
-isetshenziswa kabanzi njengendawo ephakathi ku-organic synthesis futhi ingasetshenziswa ukuhlanganisa ezinye izinhlanganisela eziphilayo.
-Ingasetshenziswa futhi njengesiqalo sokuhlanganiswa kwezidakamizwa, ukuhlanganiswa kwezibulala-zinambuzane kanye nokuhlanganiswa kodayi.
Indlela Yokulungiselela:
-noma ingalungiswa ukusabela kwe-halogenation ye-pyridine. Okokuqala, i-pyridine ne-acetic acid ithola ukusabela kwe-chlorination ukukhiqiza i-2-chloropyridine. I-2-chloropyridine ibe isiguqulelwa ku-2-chloro-3-fluoropyridine ngokusabela kwe-fluorination. Ekugcineni, i-2-chloro-3-fluoropyridine i-methylated isebenzisa ukusabela kwe-methylation.
Ulwazi Lokuphepha:
-Inhlanganisela ecasulayo engase icunule amehlo nesikhumba.
-Ngesikhathi sokusetshenziswa nokuphatha, izinyathelo ezifanele zokuphepha kufanele zithathwe, okuhlanganisa ukugqoka izibuko zokuzivikela namagilavu.
-Gwema ukuhogela umhwamuko wenhlanganisela futhi uqinisekise ukuthi usebenza endaweni enomoya omuhle.
-Lapho ugcina futhi uphatha, gwema umlilo kanye nama-oxidizing ukuze ugweme ingozi yomlilo nokuqhuma.
-Ngesikhathi sokusetshenziswa, kufanele kuqashelwe ukuhambisana nezinqubo nemithethonqubo yokusebenza yokuphepha efanele.
