2-chloro-5-chloromethyl pyridine (CCMP) yog ib qho tseem ceeb ntawm cov tshuaj nruab nrab thiab ib qho tseem ceeb nruab nrab rau kev sib txuas ntawm pyridine tshuaj tua kab xws li imidacloprid, acetamiprid, fluazinam, thiab lwm yam.
Muaj ntau ntau txoj kev sib txuas ntawm 2-chloro-5-chloromethyl pyridine. Tam sim no, 2-chloro-5-methylpyridine yog siv los ua raw khoom hauv kev lag luam, uas yog, 2-chloro-5-methylpyridine yog chlorinated los ntawm 2-chloro-5-methylpyridine nyob rau hauv lub xub ntiag ntawm catalyst kom tau 2-chloro. -5-chloromethyl pyridine. Cov 2-chloro-5-methylpyridine thiab hnyav tau ntxiv rau hauv chlorination kettle, cov catalyst tau ntxiv, thiab cov roj chlorine tau txhaj rau hauv cov tshuaj tiv thaiv nyob rau hauv cov mob reflux. Tom qab cov tshuaj tiv thaiv, thawj lub siab ntawm huab cua tau yaj, thiab tom qab ntawd cov seem qub raug tshem tawm los ntawm lub tshuab nqus tsev hauv lub tshuab hluav taws xob distillation, thiab 2-chloro-5-methylpyridine tau txais los ntawm hauv qab ntawm lub lauj kaub. Ntxiv rau qhov, muaj ntau txoj kev sib txawv siv niacin ua raw khoom, 3-methylpyridine li raw khoom, 2-chloro-5-trichloromethyl pyridine ua raw khoom. Ib qho tshwj xeeb ntawm cov txheej txheem no yog tsim lub nplhaib pyridine tom qab ua tiav ntawm chloromethylation. Lwm txoj hauv kev tsim los ntawm Teb Chaws Asmeskas Rayleigh Tuam Txhab (ReillyIndustriesInc.) siv cyclopentadiene thiab propanal raws li cov khoom siv raw rau cyclosynthesize 2-chloro-5-chloromethyl pyridine, thiab purity ntawm cov khoom yog siab li 95%, tsis muaj isomer 2. - chloro-3-chloromethyl pyridine.
25Kg / chim; Packing raws li tus neeg yuav tsum tau muaj.
Cov khoom no yuav tsum tau muab khaws cia rau hauv lub thawv kaw thiab khaws cia hauv qhov chaw txias thiab qhuav thaum khaws cia thiab thauj mus los. Tsis txhob sib tov nrog oxidants rau kev thauj mus los thiab cia.
