Taw qhia
1-Bromo-2-nitrobenzene yog cov organic compound nrog cov tshuaj formula C6H4BrNO2. Hauv qab no yog cov lus piav qhia ntawm cov khoom, kev siv, kev tsim thiab kev nyab xeeb cov ntaub ntawv ntawm 1-Bromo-2-nitrobenzene:
Xwm:
-Cov tsos mob: 1-Bromo-2-nitrobenzene yog xim dawb rau daj daj crystalline khoom.
- Melting point: txog 68-70 ° C.
- Boiling point: txog 285 degrees Celsius.
-Solubility: me ntsis soluble nyob rau hauv dej, zoo solubility nyob rau hauv cov organic solvents xws li ethers, alcohols thiab ketones.
Siv:
-Chemical reagents: siv rau oxidation-txo cov tshuaj tiv thaiv hauv cov organic synthesis thiab hloov cov tshuaj tsw qab ntawm cov tshuaj tsw qab.
-Cov tshuaj tua kab: 1-Bromo-2-nitrobenzene tuaj yeem siv los ua cov tshuaj tua kab thiab tshuaj tua kab.
-Fluorescent dyes: tuaj yeem siv los npaj cov fluorescent dyes.
Txoj Kev Npaj:
1-Bromo-2-nitrobenzene tuaj yeem npaj los ntawm cov tshuaj tiv thaiv p-nitrochlorobenzene thiab bromine. Ua ntej, p-nitrochlorobenzene yog reacted nrog bromine los tsim 2-bromonitrochlorobenzene, thiab tom qab ntawd 1-Bromo-2-nitrobenzene yog tau los ntawm thermal decomposition thiab rotation rearrangement.
Cov ntaub ntawv kev nyab xeeb:
- 1-Bromo-2-nitrobenzene yog cov organic compound nrog qee yam tshuaj lom. Hnav cov khoom tiv thaiv tus kheej tsim nyog kom tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag.
-Tsis txhob nqus nws cov plua plav lossis vapors thiab xyuas kom meej tias qhov chaw ua haujlwm muaj qhov cua zoo.
- Khaws cia kom deb ntawm hluav taws thiab oxidant kom tsis txhob muaj hluav taws kub thiab tawg.
- Kev pov tseg pov tseg yuav tsum ua raws li cov cai hauv zos thiab cov kev cai, tsis tuaj yeem muab pov tseg.
