Taw qhia
3,4-Difluorobromobenzene yog ib qho organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
Cov tsos mob: 3,4-Difluorobromobenzene yog xim tsis muaj xim rau lub teeb daj.
Ceev: approx. 1.65 g / cm³
Solubility: 3,4-difluorobromobenzene yog soluble hauv qee cov organic solvents thiab yuav luag insoluble hauv dej.
Siv:
Kev lag luam Electronics: vim nws cov khoom siv hluav taws xob zoo, 3,4-difluorobromobenzene feem ntau yog siv los ua cov khoom siv hauv cov khoom siv semiconductor.
Txoj kev:
Txoj kev npaj ntawm 3,4-difluorobromobenzene muaj cov kauj ruam hauv qab no:
Ua ntej, bromobenzene thiab bromoflurane reacted los tsim 2,3,4,5-tetrabromofluorobenzene.
2,3,4,5-tetrabromofluorobenzene ces reacted nrog hydrofluoric acid kom tau 3,4-difluorobromobenzene.
Cov ntaub ntawv kev nyab xeeb:
3,4-Difluorobromobenzene yog tshuaj lom thiab yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag nrog daim tawv nqaij thiab nqus tau nws cov vapors.
Cov txheej txheem kuaj xyuas kom raug thiab kev tiv thaiv tus kheej xws li hnav hnab looj tes tiv thaiv, tsom iav, thiab lub ntsej muag tiv thaiv yuav tsum tau ua raws li thaum siv.
Thaum khaws cia, nws yuav tsum tau khaws cia kom deb ntawm qhov hluav taws kub thiab cov oxidants, thiab tsis txhob sib cuag nrog cov acids muaj zog lossis alkalis.
Thaum pov tseg cov khoom pov tseg, nws yuav tsum muab pov tseg raws li cov kev cai lij choj thiab kev tswj hwm kom tsis txhob muaj kuab paug rau ib puag ncig.
