Ko te 2-chloro-5-chloromethyl pyridine (CCMP) he takawaenga rongoa nui me te takawaenga nui mo te whakahiatotanga o te pyridine pesticide penei i te imidacloprid, acetamiprid, fluazinam, etc.
He maha nga tikanga whakahiato o te 2-chloro-5-chloromethyl pyridine.I tenei wa, ka whakamahia te 2-chloro-5-methylpyridine hei rauemi mata i roto i te ahumahi, ara, ko te 2-chloro-5-methylpyridine ka whakamaua e te 2-chloro-5-methylpyridine i te aroaro o te whakakorikori kia whiwhi 2-chloro. -5-chloromethyl pyridine.I tapirihia te 2-chloro-5-methylpyridine me te whakarewa ki te kettle chlorination, ka tapirihia te whakakorikori, ka werohia te hau maota ki te tauhohenga i raro i te ahua o te reflux.I muri i te tauhohenga, ka rewa te pehanga hau tuatahi, katahi ka tangohia te hautanga o mua ma te korehau i roto i te kettle whakamaarama, ka riro mai te 2-chloro-5-methylpyridine mai i raro o te ketere.I tua atu i te , he maha nga huarahi rereke e whakamahi ana i te niacin hei rauemi mata, 3-methylpyridine hei rauemi mata, 2-chloro-5-trichloromethyl pyridine hei rauemi mata.Ko tetahi ahuatanga noa o enei tikanga ko te hanganga o te mowhiti pyridine ka whai i te otinga o te chloromethylation.Ko tetahi atu huarahi i whakawhanakehia e te United States Rayleigh Company (ReillyIndustriesInc.) ka tango i te cyclopentadiene me te propanal hei timata i nga rauemi mata ki te huri tika i te 2-chloro-5-chloromethyl pyridine, a ko te ma o te hua ka rite ki te 95%, kaore he isomer 2 -chloro-3-chloromethyl pyridine.
25Kg/paera;Taapiri kia rite ki nga whakaritenga a te kaihoko.
Me penapena tenei hua ki roto i te ipu hiri ka pupuri ki te waahi makariri me te maroke i te wa e rokiroki ana me te kawe.Kaua e uru ki nga waikura mo te kawe me te rokiroki.
