I-2-chloro-5-chloromethyl pyridine (i-CCMP) yinto ebalulekileyo ye-pharmaceutical intermediate kunye ne-intermediate ebalulekileyo ye-synthesis ye-pyridine pesticide agents ezifana ne-imidacloprid, i-acetamiprid, i-fluazinam, njl.
Kukho iindlela ezininzi zokuhlanganisa i-2-chloro-5-chloromethyl pyridine.Okwangoku, i-2-chloro-5-methylpyridine isetyenziswa njengento eluhlaza kwishishini, oko kukuthi, i-2-chloro-5-methylpyridine i-chlorine yi-2-chloro-5-methylpyridine phambi kwe-catalyst ukufumana i-2-chloro. -5-chloromethyl pyridine.I-2-chloro-5-methylpyridine kunye ne-solvent yongezwa kwi-kettle ye-chlorination, i-catalyst yongezwa, kwaye igesi ye-chlorine ifakwe kwi-reaction phantsi kwemeko ye-reflux.Emva kokuphendula, uxinzelelo lokuqala lwe-atmospheric lwachithwa, kwaye i-fraction yangaphambili yasuswa nge-vacuum kwi-kettle ye-distillation, kwaye i-2-chloro-5-methylpyridine ifunyenwe phantsi kweketile.Ukongeza kwi-, kukho iindlela ezahlukeneyo ezahlukeneyo ezisebenzisa i-niacin njengento ekrwada, i-3-methylpyridine njengento ekrwada, i-2-chloro-5-trichloromethyl pyridine njengezinto eziluhlaza.Into eqhelekileyo yezi ndlela kukubunjwa kweringi yepyridine elandelwa kukugqitywa kwe-chloromethylation.Enye indlela ephuhliswe yi-United States Rayleigh Company (i-ReillyIndustriesInc.) ithatha i-cyclopentadiene kunye ne-propanal njengesiqalo sezinto eziluhlaza ukuya ngqo kwi-cyclosynthesize 2-chloro-5-chloromethyl pyridine, kwaye ukucoceka kwemveliso kuphezulu njenge-95%, ngaphandle kwe-isomer 2. -chloro-3-chloromethyl pyridine.
