Taw qhia
M-bromophenol. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm m-bromophenol:
Zoo:
Cov tsos mob: M-bromophenol yog dawb crystalline lossis crystalline hmoov.
Solubility: soluble hauv cov kuab tshuaj organic xws li ethanol thiab ether, insoluble hauv dej.
Cov khoom siv tshuaj: M-brominated phenol tuaj yeem oxidized ntawm qhov kub thiab txias thiab tuaj yeem txo mus rau m-bromobenzene los ntawm kev txo cov neeg ua haujlwm.
Siv:
Hauv thaj teb ntawm cov tshuaj tua kab: m-bromophenol kuj tseem siv tau los ua ib qho nruab nrab hauv cov tshuaj tua kab tua kab hauv kev ua liaj ua teb.
Lwm yam kev siv: m-bromophenol kuj tseem siv tau los ua cov khoom siv raw rau cov organic synthesis cov tshuaj tiv thaiv, nrog rau cov dyes, coatings thiab lwm yam teb.
Txoj kev:
M-brominated phenol feem ntau tuaj yeem tau los ntawm bromination ntawm p-nitrobenzene. Ua ntej, p-nitrobenzene yog yaj hauv sulfuric acid, ces cuprous bromide thiab dej ntxiv los tsim m-brominated phenol los ntawm cov tshuaj tiv thaiv, thiab thaum kawg neutralized nrog alkali.
Cov ntaub ntawv kev nyab xeeb:
M-bromophenol yog tshuaj lom thiab yuav tsum tau zam los ntawm kev nqus, nqus, lossis tiv tauj nrog daim tawv nqaij thiab qhov muag.
Cov cuab yeej tiv thaiv tus kheej xws li hnab looj tes tiv thaiv, tsom iav thiab daim npog ntsej muag yuav tsum hnav thaum siv kom muaj cua zoo.
Thaum khaws cia thiab tuav m-bromophenol, tsis txhob sib cuag nrog cov oxidants muaj zog, muaj zog acids thiab muaj zog hauv paus kom tsis txhob muaj kev phom sij txaus ntshai.
