2-CHLORO-6-FLUOROPYRIDINE (CAS# 20885-12-5) Isingeniso

I-2-chloro-6-fluoropyridine iyinhlanganisela ye-organic ene-chemical formula C5H2ClFN. Iwuketshezi olungenambala olunephunga elifana ne-pyridine.Okunye ukusetshenziswa okuyinhloko kwe-2-chloro-6-fluoropyridine kufana nesibulala-zinambuzane esiphakathi. Ingasetshenziselwa ukuhlanganisa ama-insecticide ahlukahlukene kanye nama-herbicides ukuze kulawulwe futhi kuvikelwe amapulazi nezilimo ze-horticultural.

I-2-chloro-6-fluoropyridine ngokuvamile itholakala nge-fluorination kanye ne-chlorination ye-pyridine. Igesi ye-fluorine ne-hydrochloric acid ngokuvamile isetshenziswa njengama-reactants, futhi ukusabela kwenziwa ngesikhathi esifanele sokushisa nesikhathi sokuphendula.

Mayelana nolwazi lokuphepha, i-2-chloro-6-fluoropyridine iyikhemikhali enobuthi, ukuthintana noma ukuhogela okungase kubangele izingozi empilweni. Iyacasula, iyacasula futhi ilimaza amehlo, isikhumba kanye nesistimu yokuphefumula. Ngakho-ke, lapho uphatha futhi usebenzisa i-2-chloro-6-fluoropyridine, kufanele kuthathwe izinyathelo zokuphepha ezifanele, njengokugqoka izibuko zokuzivikela, amagilavu ​​namamaski obuso, nokuqinisekisa ukuthi ukuhlinzwa kwenziwa endaweni enomoya omuhle. Ngemuva kokusetshenziswa, udoti kufanele ulahlwe ngendlela efanele ukuze kugwenywe ukungcoliswa kwemvelo.
