3-Bromo-2-fluoro-5-methylpyridine (CAS # 17282-01-8) Taw qhia
yog cov kua uas tsis muaj xim rau daj ntseg daj. Nws muaj ib tug pungent tsw ntawm chav tsev kub. Qhov ntom ntawm cov compound yog siab dua, thiab nws cov ntsiab lus melting thiab boiling point nce nrog qhov nce ntawm bromine cov ntsiab lus.
Siv:
Nws yog tsuas yog siv los ua reagent lossis nruab nrab hauv cov organic synthesis. Nws tuaj yeem siv rau hauv kev npaj cov tshuaj, tshuaj tua kab thiab lwm yam organic tebchaw. Nws kuj tseem siv tau los ua cov tshuaj reagent hauv kev tshawb fawb thiab chaw soj nstuam.
Txoj kev:
Cov txheej txheem ntawm kev npaj cov ntsiav tshuaj feem ntau suav nrog cov tshuaj tiv thaiv ob-kauj ruam. Ua ntej, bromomethylpyridine yog reacted nrog poov tshuaj fluoride nyob rau hauv cov organic hnyav los qhia ib tug fluorine atom. Tom qab ntawd bromofluoro compound yog oxidized rau cov halogen sib xws nrog hydrogen peroxide los yog lwm yam oxidizing agents.
Cov ntaub ntawv kev nyab xeeb:
Nws yog ib qho organic compound thiab yuav tsum tau saib xyuas. Thaum siv lossis npaj, yuav tsum muaj kev ntsuas kev nyab xeeb tsim nyog, xws li hnav cov hnab looj tes tiv thaiv tshuaj, tsom iav thiab tso pa tawm sab nraum chav kuaj. Tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag, thiab kom deb ntawm hluav taws. Thaum khaws cia, khaws lub ntim ntim thiab muab tso rau hauv qhov chaw txias, qhuav. Nyob rau hauv rooj plaub ntawm kev noj los yog kev sib cuag ntawm daim tawv nqaij, nrhiav kev kho mob tam sim ntawd.
