2-chloro-5-chloromethyl pyrididel (ccmp) ndi gawo lofunikira lofunikira kuti azigwiritsa ntchito mankhwala a pidacloprid monga Imidacloprid, catabiniprid, etc.
Pali njira zambiri za synthesis za 2-chloro-5-chloromethyl pyrididine. Pakadali pano, 2-chloro-5-methylpyridine amagwiritsidwa ntchito ngati zopangira m'makampaniwo, ndiye kuti, chloro-5-chloro-5-chloromethyl proromethyl prororomethyl pyrididine. The 2 chloro-5-methyllyridine ndi sonsylpyridididine ndi solvent adawonjezeredwa ku ketoto, chothandizira adawonjezeredwa, ndipo mpweya wa chlorine udalowetsedwa kuti azolowere. Pambuyo pochita, kukakamizidwa kwa mlengalenga koyamba kunasungunuka, kenako seraction wakaleyo idachotsedwa pa ketulo yopadera, ndipo 2-chloro-5-methylpyridine adapezeka kuchokera pansi pa ketulo. Kuphatikiza pa, pali njira zosiyanasiyana zogwiritsira ntchito Niacn monga raw zopangira, 3-methylpyridine ngati zida zomera, 2-chlororomethyl zipatso zosaphika. Chinthu chodziwika bwino cha njirazi ndikupanga mphete ya PYYING kumatsatiridwa ndi kumaliza kwa chloromethyty. Njira ina yomwe inayambitsidwa ndi United States Ruleagh Company (Revillindustilinc (Revillintinc)
25kg / mbiya; Kulongedza malinga ndi zofunikira za makasitomala.
Izi ziyenera kusungidwa mumtsuko wosindikizidwa ndikusungidwa m'malo ozizira komanso owuma nthawi yosungirako komanso mayendedwe. Osasakaniza ndi oxidants oyenda ndikusungirako.
