Taw qhia
1-Bromo-3-nitrobenzene yog cov organic compound nrog cov tshuaj formula C6H4BrNO2. Cov hauv qab no yog cov lus piav qhia ntawm qee yam ntawm nws cov khoom, kev siv, txoj kev thiab cov ntaub ntawv kev nyab xeeb:
Xwm:
1-Bromo-3-nitrobenzene yog cov xim tsis muaj xim lossis daj daj crystalline hmoov nrog cov ntxhiab tsw tshwj xeeb. Nws yog insoluble hauv dej thiab soluble hauv cov kuab tshuaj organic.
Siv:
1-Bromo-3-nitrobenzene yog ib qho tseem ceeb ntawm cov organic synthesis nruab nrab, uas tuaj yeem siv los ua ke ntau yam tshuaj, dyes thiab tshuaj tua kab. Nws kuj tseem siv tau los ua reagent thiab catalyst rau cov tshuaj tiv thaiv.
Txoj Kev Npaj:
1-Bromo-3-nitrobenzene tuaj yeem ua ke los ntawm bromination ntawm nitrobenzene. Bromine thiab sulfuric acid feem ntau yog siv los ua cov tshuaj brominating, uas yog reacted nrog nitrobenzene muab 1-Bromo-3-nitrobenzene.
Cov ntaub ntawv kev nyab xeeb:
1-Bromo-3-nitrobenzene muaj teeb meem rau tib neeg lub cev thiab ib puag ncig. Nws yog cov khoom siv hluav taws xob thiab yuav tsum tau khaws cia kom deb ntawm cov nplaim taws qhib thiab qhov kub thiab txias. Kev sib cuag nrog daim tawv nqaij lossis nqus tau nws cov vapors tuaj yeem ua rau khaus thiab raug mob. Hnav hnab looj tes thiab tsom iav thaum tuav thiab siv, thiab xyuas kom muaj cua zoo. Thaum khaws cia, nws yuav tsum muab cia rau hauv qhov chaw qhuav, txias thiab deb ntawm oxidants thiab acids. Nyob rau hauv cov ntaub ntawv ntawm kev huam yuaj, kev ntsuas tsim nyog yuav tsum tau coj los daws thiab ntxuav. Ua ntej siv, nws raug nquahu kom xa mus rau phau ntawv qhia kev nyab xeeb kev ua haujlwm thiab cov ntaub ntawv kev nyab xeeb ntawm cov ntaub ntawv.
