Taw qhia
M-fluorobenzyl bromide yog ib qho organic compound.
Zoo:
M-fluorobenzyl bromide yog cov kua tsis muaj xim lossis daj daj nrog cov ntxhiab tsw tshwj xeeb. Nws tuaj yeem yaj hauv feem ntau cov kuab tshuaj organic xws li cawv, ethers, thiab aromatics.
Kev Siv: Nws kuj tuaj yeem siv los ua cov khoom siv rau cov hlau hnyav ions thiab ua cov khoom nruab nrab rau cov dyes.
Txoj kev:
M-fluorobenzyl bromide tuaj yeem npaj los ntawm reacting m-chlorobromobenzene nrog hydrogen fluoride. Hydrofluoric acid, glacial acetic acid, thiab hydrogen peroxide feem ntau yog siv los ua reactants. Cov tshuaj tiv thaiv yuav tsum tau nqa tawm ntawm qhov kub thiab txias nrog kev ua haujlwm pab pawg tiv thaiv, ua raws li bromination nyob rau hauv alkaline tej yam kev mob.
Cov ntaub ntawv kev nyab xeeb:
M-fluorobenzyl bromide yog qhov ruaj khov ntawm chav tsev kub, tab sis tuaj yeem ua rau muaj kev phom sij thaum raug kub hnyiab, qhib nplaim taws, lossis muaj zog oxidizing cov neeg ua haujlwm. Nws yog khaus thiab corrosive thiab tuaj yeem ua rau puas tsuaj rau daim tawv nqaij, qhov muag, thiab ua pa. Kev saib xyuas yuav tsum tau hnav cov hnab looj tes tiv thaiv, tsom iav thiab lub tshuab ua pa thaum siv, thiab xyuas kom meej tias lawv ua haujlwm hauv qhov chaw muaj cua zoo.
