Taw qhia
2,5-Dichloro-3-methylpyridine yog cov organic compound. Cov hauv qab no yog kev qhia txog qee yam ntawm nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Cov Khoom Siv: 2,5-Dichloro-3-methylpyridine yog cov kua tsis muaj xim lossis daj daj uas yog nplaim taws.
Kev Siv: 2,5-Dichloro-3-methylpyridine feem ntau yog siv los ua ib qho tseem ceeb nruab nrab ntawm cov organic synthesis. Nws kuj tseem siv tau los ua ib feem hauv cov kuab tshuaj, cov catalysts, thiab lubricants.
Txoj kev npaj: Muaj ntau txoj hauv kev los npaj 2,5-dichloro-3-methylpyridine. Ib txoj hauv kev yog kom tau txais cov khoom nruab nrab los ntawm kev ua haujlwm methylpyridine nrog thionyl chloride, thiab tom qab ntawd chlorination los tsim cov khoom lag luam. Lwm txoj hauv kev npaj muaj xws li txo qis thiab tshuaj chlorination, thiab lwm yam.
Cov ntaub ntawv kev nyab xeeb: 2,5-dichloro-3-methylpyridine yuav tsum tau siv rau hauv cov txheej txheem kev nyab xeeb. Nws yog khaus thiab corrosive rau lub qhov muag, tawv nqaij, thiab ua pa ib ntsuj av tau thiab yuav tsum tau yaug nrog dej ntau tam sim ntawd tom qab sib cuag. Thaum ua haujlwm, cov cuab yeej tiv thaiv tsim nyog xws li tsom iav, hnab looj tes thiab khaub ncaws tiv thaiv yuav tsum hnav. Xyuas kom qhov chaw ua haujlwm zoo ventilated thiab tsis txhob nqus nws cov vapors. Thaum khaws cia, khaws cia rau hauv qhov chaw airtight, txias, qhuav, deb ntawm hluav taws thiab oxidants.
