Taw qhia
Bromoethylpyridine yog ib qho organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm bromoethylpyridine:
Zoo:
Bromoethylpyridine yog cov kua uas tsis muaj xim rau yellowish nrog ib qho aromatic amine zoo li aminophenol saj. Nws muaj solubility zoo thiab yog soluble hauv cawv, ethers thiab ester solvents.
Siv:
Bromoethylpyridine feem ntau yog siv los ua reagent thiab nruab nrab hauv cov organic synthesis. Bromoethylpyridine kuj tseem siv tau ua ib qho surfactant, pyrotechnic fluorescent tshuaj, thiab lwm yam.
Txoj kev:
Bromoethylpyridine feem ntau yog tsim los ntawm cov tshuaj tiv thaiv ntawm ethyl bromide thiab pyridine nyob rau hauv alkaline tej yam kev mob. Hauv cov tshuaj tiv thaiv, bromine atom hauv ethyl bromide hloov cov hydrogen atom hauv pyridine molecule los tsim ethylpyridine bromide.
Cov ntaub ntawv kev nyab xeeb:
Kev ceev faj txog kev nyab xeeb hauv qab no yuav tsum tau ua thaum siv bromoethylpyridine:
Hnav looj tsom iav thiab hnab looj tes thaum ua haujlwm, thiab tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag.
Ua haujlwm nyob rau hauv qhov chaw uas muaj cua zoo thiab tsis txhob nqus pa los yog vapors.
Thaum khaws cia, nws yuav tsum khaws cia kom deb ntawm qhov hluav taws kub thiab cua sov, thiab kom deb ntawm tshav ntuj ncaj qha.
Bromoethylpyridine yog khaus thiab cov txheej txheem kev nyab xeeb ntawm kev ua haujlwm yuav tsum tau ua raws li nruj me ntsis.
Thaum siv los yog tuav bromoethylpyridine, nws yog ib qho tseem ceeb uas yuav tsum tau ua raws li lub chaw soj nstuam cov txheej txheem kev nyab xeeb thiab ua ib qho kev ntsuam xyuas kev nyab xeeb ntawm tus kheej raws li qhov xwm txheej.
