Taw qhia
O-trifluoromethylbenzaldehyde. Nws yog soluble hauv cov kuab tshuaj organic xws li cawv thiab ethers thiab insoluble hauv dej.
Siv:
o-trifluoromethylbenzaldehyde feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis.
Txoj kev:
Muaj ntau ntau txoj hauv kev rau kev npaj ntawm o-trifluoromethylbenzaldehyde. Ib qho ntawm cov kev siv feem ntau yog ua rau benzaldehyde nrog trifluoroformic acid kom tau o-trifluoromethylbenzaldehyde los ntawm cov kua qaub catalysis.
Cov ntaub ntawv kev nyab xeeb:
O-trifluoromethylbenzaldehyde yog ib qho organic compound nrog qee yam kev phom sij. Yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag nrog cov tawv nqaij thiab qhov muag, thiab kom tsis txhob nqus cov pa los yog plua plav thaum siv nws. Nws yuav tsum tau ua haujlwm nyob rau hauv qhov chaw muaj cua zoo thiab hnav cov cuab yeej tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab lwm yam. Thaum khaws cia, nws yuav tsum tau muab kaw kom nruj kom deb ntawm qhov hluav taws kub thiab oxidants. Cov txheej txheem kev nyab xeeb ntsig txog kev ua haujlwm yuav tsum tau ua raws li qhov xwm txheej.
