2-chloro-5-chloromethyl pyridine (CCMP) ndi mankhwala ofunikira apakati komanso ofunikira pakupanga mankhwala ophera tizilombo a pyridine monga imidacloprid, acetamiprid, fluazinam, etc.
Pali njira zambiri zopangira 2-chloro-5-chloromethyl pyridine.Pakali pano, 2-chloro-5-methylpyridine amagwiritsidwa ntchito ngati zopangira m'makampani, ndiko kuti, 2-chloro-5-methylpyridine ndi 2-chloro-5-methylpyridine pamaso pa chothandizira kupeza 2-chloro. -5-chloromethyl pyridine.2-chloro-5-methylpyridine ndi zosungunulira zinawonjezeredwa ku ketulo ya chlorination, chothandizira chinawonjezeredwa, ndipo mpweya wa chlorine unalowetsedwa muzochita pansi pa chikhalidwe cha reflux.Pambuyo pazimenezi, mphamvu yoyamba ya mumlengalenga inasungunuka, ndiyeno kachigawo kakang'ono kameneka kanachotsedwa ndi vacuum mu ketulo ya distillation, ndipo 2-chloro-5-methylpyridine inapezedwa pansi pa ketulo.Kuphatikiza pa , pali njira zosiyanasiyana zogwiritsira ntchito niacin monga zopangira, 3-methylpyridine ngati zopangira, 2-chloro-5-trichloromethyl pyridine ngati zopangira.Chinthu chodziwika bwino cha njirazi ndi kupanga mphete ya pyridine yotsatiridwa ndi kutsirizidwa kwa chloromethylation.Njira ina yopangidwa ndi United States Rayleigh Company (ReillyIndustriesInc.) imatenga cyclopentadiene ndi propanal ngati zoyambira zopangira kuti zipangitse cyclosynthesize 2-chloro-5-chloromethyl pyridine, ndipo chiyero cha mankhwalawa ndi chokwera mpaka 95%, popanda isomer 2. - chloro-3-chloromethyl pyridine.
25Kg / mbiya;Kulongedza malinga ndi zomwe kasitomala akufuna.
Izi ziyenera kusungidwa mu chidebe chosindikizidwa ndikusungidwa pamalo ozizira ndi owuma panthawi yosungira ndi kuyendetsa.Osasakanikirana ndi okosijeni ponyamula ndi kusunga.
