2-chloro-5-chloromethyl pyridine (CCMP) inokosha yemishonga yepakati uye yakakosha yepakati pekugadzirwa kwepyridine pesticide agents seimidacloprid, acetamiprid, fluazinam, nezvimwewo.
Kune dzakawanda nzira dzekugadzira 2-chloro-5-chloromethyl pyridine.Parizvino, 2-chloro-5-methylpyridine inoshandiswa seyakabikwa muindasitiri, kureva, 2-chloro-5-methylpyridine inonatswa ne 2-chloro-5-methylpyridine pamberi peiyo catalyst kuwana 2-chloro. -5-chloromethyl pyridine.Iyo 2-chloro-5-methylpyridine uye solvent yakawedzerwa kune chlorination kettle, iyo catalyst yakawedzerwa, uye chlorine gasi yakaiswa mukuita pasi peiyo reflux mamiriro.Mushure mekuita, mhepo yekutanga yemhepo yakanyungudutswa, uye ipapo chikamu chekare chakabviswa nevhavha mu kettle ye distillation, uye 2-chloro-5-methylpyridine yakawanikwa kubva pasi peketero.Pamusoro peiyo, kune nzira dzakasiyana dzakasiyana dzinoshandisa niacin seyakabikwa, 3-methylpyridine seyakabikwa, 2-chloro-5-trichloromethyl pyridine seyakabikwa.Chinhu chinozivikanwa chemaitiro aya ndiko kuumbwa kwemhete yepyridine inoteverwa nekupedzwa kwechloromethylation.Imwe nzira yakagadziridzwa neUnited States Rayleigh Company (ReillyIndustriesInc.) inotora cyclopentadiene uye propanal sekutanga zvinhu zvakasvibirira zvakananga cyclosynthesize 2-chloro-5-chloromethyl pyridine, uye kuchena kwechigadzirwa kwakakwira se95%, isina isomer 2. -chloro-3-chloromethyl pyridine.
25Kg / mbiya;Kurongedza zvinoenderana nezvinodiwa nemutengi.
Ichi chigadzirwa chinofanira kuchengetwa mumudziyo wakavharwa uye kuchengetwa munzvimbo inotonhorera uye yakaoma panguva yekuchengetedza uye kutakura.Usasanganise nemaoxidants ekufambisa nekuchengetedza.
