Taw qhia
4-(Trifluoromethoxy) benzyl bromide yog cov organic compound.
Ib qho ntawm nws txoj kev siv tseem ceeb yog ua ib qho reagent thiab nruab nrab hauv cov organic synthesis. Cov khoom tshwj xeeb ntawm nws pawg trifluoromethoxy, nws tuaj yeem siv los qhia txog pawg trifluoromethoxy.
Kev npaj ntawm 4-(trifluoromethoxy) benzyl bromide feem ntau tau txais los ntawm cov tshuaj tiv thaiv ntawm benzyl bromide thiab trifluoromethanol. Ntawm lawv, benzyl bromide reacts nrog trifluoromethanol nyob rau hauv alkaline tej yam kev mob rau daim ntawv 4-(trifluoromethoxy) benzyl bromide.
Nws yog ib qho organohalide uas ua rau khaus thiab lom, thiab yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag ntawm daim tawv nqaij thiab qhov muag thaum ua haujlwm. Nws yuav tsum tau siv rau hauv qhov chaw uas muaj cua zoo thiab muaj kev tiv thaiv tsim nyog, xws li hnav looj tsom iav, hnab looj tes thiab khaub ncaws tiv thaiv. Nws yuav tsum tau khaws cia kom deb ntawm qhov hluav taws kub thiab oxidants, thiab khaws cia rau hauv lub thawv airtight kom tsis txhob muaj huab cua. Nyob rau hauv qhov kev tshwm sim ntawm kev huam yuaj, nws yuav tsum tau muab tshem tawm sai sai thiab tsis txhob nkag mus rau hauv lub qhov dej los yog kav dej.
