1-bromo-2,3,4-trifluorobenzene (CAS # 176317-02-5) Taw qhia
1-bromo-2,3,4-trifluorobenzene yog cov kua tsis muaj xim nrog cov ntxhiab tsw muaj zog hydrocarbon. Nws muaj qhov kub ntawm -19 ° C thiab qhov kub ntawm 60 ° C. Nws yog volatile thiab soluble hauv ethanol thiab Ether cov kuab tshuaj.
Siv:
1-bromo-2,3,4-trifluorobenzene yog siv los ua ib qho tseem ceeb nruab nrab ntawm cov organic synthesis. Nws muaj ntau yam kev siv hauv cov tshuaj synthesis, Pesticide Synthesis, dye synthesis thiab lwm yam. Nws kuj tseem siv tau los ua ib feem ntawm photoresist, ib qho ntxiv ntawm cov khoom siv hluav taws xob, lossis lwm yam.
Txoj kev:
Kev npaj ntawm 1-bromo-2,3,4-trifluorobenzene tuaj yeem ua tau los ntawm ntau txoj hauv kev. Ib txoj hauv kev yog los ua bromobenzene nrog hydrogen fluoride muab 1-bromo-2,3,4-trifluorobenzene. Nws tuaj yeem npaj tau los ntawm kev ua haujlwm bromobenzene nrog antimony trifluoride.
Cov ntaub ntawv kev nyab xeeb:
1-bromo-2,3,4-trifluorobenzene yog teeb meem rau tib neeg lub cev thiab ib puag ncig. Nws yog cov kua hluav taws xob uas ua rau muaj cov pa phem thaum raug cov nplaim taws qhib lossis kub kub. Kev sib cuag nrog daim tawv nqaij thiab qhov muag yuav ua rau khaus thiab kub hnyiab. Yog li ntawd, thaum siv los yog tuav 1-bromo-2,3,4-trifluorobenzene, koj yuav tsum hnav cov khoom tiv thaiv tsim nyog thiab xyuas kom meej tias kev ua haujlwm tau ua tiav hauv qhov chaw muaj cua zoo.
