2-chloro-5-chloromethyl pyridine (CCMP) nigihe kinini cyimiti yimiti nintera yingenzi muguhuza imiti yica udukoko twa pyridine nka imidacloprid, acetamiprid, fluazinam, nibindi.
Hariho uburyo bwinshi bwa synthesis ya 2-chloro-5-chloromethyl pyridine. Kugeza ubu, 2-chloro-5-methylpyridine ikoreshwa nkibikoresho fatizo mu nganda, ni ukuvuga, 2-chloro-5-methylpyridine ikorwamo chlorine na 2-chloro-5-methylpyridine imbere ya catalizator kugirango ibone 2-chloro -5-chloromethyl pyridine. 2-chloro-5-methylpyridine na solvent byongewemo mu isafuriya ya chlorine, catalizator yongerwamo, kandi gaze ya chlorine yatewe mubitekerezo nyuma yo kugaruka. Nyuma yo kubyitwaramo, umuvuduko wambere wikirere washeshwe, hanyuma igice cyambere cyakuweho na vacuum mumasafuriya, hanyuma 2-chloro-5-methylpyridine yabonetse munsi yicyayi. Usibye i, hariho inzira zitandukanye zitandukanye ukoresheje niacin nkibikoresho fatizo, 3-methylpyridine nkibikoresho fatizo, 2-chloro-5-trichloromethyl pyridine nkibikoresho fatizo. Ikintu gisanzwe muri ubu buryo ni ugukora impeta ya pyridine ikurikirwa no kurangiza chloromethylation. Indi nzira yatunganijwe n’isosiyete yo muri Amerika Rayleigh (ReillyIndustriesInc.) Ifata cyclopentadiene na propanal nko gutangiza ibikoresho fatizo kugirango cyclosynthesize itaziguye 2-chloro-5-chloromethyl pyridine, kandi ubuziranenge bwibicuruzwa buri hejuru ya 95%, nta isomer 2 -chloro-3-chloromethyl pyridine.
25Kg / ingunguru; Gupakira ukurikije ibyo umukiriya asabwa.
Ibicuruzwa bigomba kubikwa mu kintu gifunze kandi bikabikwa ahantu hakonje kandi humye mugihe cyo kubika no gutwara. Ntukavange na okiside yo gutwara no kubika.
