2-chloro-5-chloromethyl pyridine (CCMP) yog ib qho tseem ceeb ntawm pyridine rau cov synthesis ntawm synthesis ntawm synthesis ntawm synthesis ntawm synthesis ntawm synthesis ntawm synthesis ntawm synthesis, acetamiprid, fluazinam, thiab lwm yam.
Muaj ntau hom lus synthesis ntawm 2-chloro-5-chloromethyl pyridine. Tam sim no, 2-chloro-5-Methylpyridine yog siv los ua cov khoom siv raw hauv kev lag luam, uas yog, 2-chloro-5-chloro-5-chloro-5-chloro-5-chloro-5-chloromethyl pyridine. Qhov 2-chloro-5-metylpyridine thiab cov kuab tshuaj tau ntxiv rau cov tshuaj nplaum, thiab cov tshuaj chlorine ntxiv, thiab cov tshuaj chlorine roj tau txhaj rau hauv cov tshuaj tiv thaiv raws li cov tshuaj tiv thaiv. Tom qab cov tshuaj tiv thaiv, thawj lub siab siab tau yaj, thiab tom qab ntawd cov qub feem tau raug tshem tawm los ntawm lub tsev pheeb suab, thiab 2-chloro-5-Methylpyridine tau txais hauv qab ntawm lub lauj kaub. Ntxiv rau cov, muaj ntau txoj kev sib txawv uas siv niacin li cov khoom siv raw, 3-Methylpyridine li cov khoom siv raw, 2-trichloromethyl pyridine li cov khoom siv raw. Ib qho kev sib txawv ntawm cov hau kev no yog tsim ntawm lub nplhaib pyridine ua raws li kev ua tiav ntawm chloromethylation. Lwm txoj hauv kev tsim los ntawm United States RayleC.) Yuav siv cov khoom siv ua kom zoo nkauj rau kev pib ua kom zoo li 95%, tsis muaj ISOMER 2-chloro-3-chloromethyl pyridine.
25kg / Barel; Ntim raws li tus neeg siv khoom.
Cov khoom no yuav tsum tau muab cia rau hauv cov thawv ntim thiab khaws cia rau hauv qhov chaw txias thiab qhuav thaum lub sijhawm cia thiab tsheb thauj mus los. Tsis txhob sib xyaw nrog oxidants rau kev thauj mus los thiab cia.
