I-2-Chloro-5-Chloromethyl Pyridine (CCMP) ingumphakathi obalulekile wezemithi kanye nomphakathi obalulekile wokuhlanganiswa kwama-pyridine pesticide agents ageridine, i-acetamiprid, i-flaazinam, njll.
Kunezindlela eziningi ze-synthesis ze-2-Chloro-5-chloromethyl pyridine. Njengamanje, 2-chloro-5-methylpyridine isetshenziswa njengento eluhlaza embonini, okungukuthi, 2-chloro-5-methylpyridine ihlolwe ngu-2-chloro-5-chloromethyy pyridine. I-2-Chloro-5-Huthylpyridine futhi i-solvent yengezwe ku-chlorination kettle, i-catalyst yangezwa, futhi igesi ye-chlorine yafakwa ekuphendukelweni ngaphansi kwesimo se-Reflux. Ngemuva kokusabela, ingcindezi yokuqala yasemkhathini yachithwa, kwathi ingxenye yangaphambilini yasuswa nge-vacuum ku-distillation kettle, kwatholakala ama-2-chloro-5-methylpyridine atholakala ezansi kwelettle. Ngaphezu kwalokho, kunemizila ehlukahlukene ehlukene usebenzisa i-niacin njengento eluhlaza, ama-3-methylpyridine njenge-distential eluhlaza, ama-2-chloro-5-trichloromethyl pyridine njengento eluhlaza. Isici esijwayelekile salezi zindlela ukwakheka kwendandatho ye-pyridine elandelwa ukugcwaliswa kwe-chlorometylation. Enye indlela ethuthukiswe yi-United States Rayleigh Company (Reillyindustiesnic.) Kuthatha i-cyclopentadiene kanye nePropational njengokuqala kokudla okuvuselelayo kuya kuma-cyclosynthesize ama-95% aphezulu, ngaphandle kwe-isomer 2-Chloro-3-Chloromethyl pyridine.
I-25kg / umgqomo; Ukupakisha ngokuya ngezidingo zekhasimende.
Lo mkhiqizo kufanele ugcinwe esitsheni esivalwe uphawu futhi ugcinwe endaweni epholile neyomile ngesikhathi sokugcina nokuhamba. Ungahlanganisi ne-oxidants yokuhamba nokugcinwa.
