Taw qhia
2,4-Dibromoaniline yog ib qho organic compound. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
2,4-Dibromoaniline yog cov xim tsis muaj xim uas yog soluble hauv cov kuab tshuaj organic xws li ethanol, acetone thiab ether, thiab me ntsis soluble hauv dej. Nws muaj ib tug muaj zog pungent tsw.
Siv:
2,4-Dibromoaniline muaj ntau yam kev siv hauv cov organic synthesis. Nws tuaj yeem siv los ua cov khoom ua ntej rau dyes thiab pigments, thiab tseem tuaj yeem siv los npaj cov khoom siv xws li fluorescent brighteners.
Txoj kev:
Txoj kev npaj ntawm 2,4-dibromoaniline tuaj yeem tau txais los ntawm bromination cov tshuaj tiv thaiv ntawm aniline thiab bromine nyob rau hauv qhov tsim nyog cov tshuaj tiv thaiv. Ib txoj kev npaj siv feem ntau yog ntxiv bromine rau aniline nyob rau hauv alkaline tej yam kev mob, ces react nws los ntawm qhov kub thiab txias stirring, thiab thaum kawg mus rau cov kauj ruam ntawm pom, ntxuav thiab crystallization kom tau lub hom phiaj cov khoom.
Cov ntaub ntawv kev nyab xeeb:
2,4-Dibromoaniline yog ib qho tshuaj tiv thaiv kab mob uas tuaj yeem ua rau khaus thiab kub hnyiab ntawm daim tawv nqaij thiab qhov muag. Cov hnab looj tes tiv thaiv tsim nyog, tsom iav, thiab khaub ncaws tiv thaiv yuav tsum hnav thaum ua haujlwm kom tsis txhob nqus pa. Nws yuav tsum tau ua nyob rau hauv ib qho chaw zoo-ventilated thiab tsis txhob sib cuag nrog cov khoom flammable. Kev saib xyuas yuav tsum tau ua kom ua raws li cov cai tswj kev nyab xeeb thaum lub sij hawm khaws cia thiab tuav kom tsis txhob muaj hluav taws xob thiab hluav taws xob zoo li qub.
