Taw qhia
Fluorobenzaldehyde) yog ib qho organic compound uas belongs rau cov aromatic aldehyde pawg ntawm cov tebchaw. Nws yog fluorinated derivative ntawm benzaldehyde thiab muaj ib lub nplhaib benzene thiab fluorine atom txuas rau tib cov pa roj carbon.
Nyob rau hauv cov nqe lus ntawm nws cov khoom, fluorobenzaldehyde yog cov kua tsis muaj xim nrog ib qho tsw qab ntawm chav tsev kub. Nws muaj solubility zoo thiab soluble nyob rau hauv ntau yam organic solvents xws li cawv, ethers thiab ketones.
Fluorobenzaldehyde yog dav siv nyob rau hauv lub teb ntawm organic synthesis. Fluorobenzaldehyde kuj tseem siv rau hauv kev tsim cov txheej, yas, roj hmab, thiab lwm yam ntaub ntawv.
Muaj ntau txoj hauv kev los npaj fluorobenzaldehyde. Ib txoj hauv kev yog tau los ntawm kev ua haujlwm nrog benzaldehyde nrog fluorinating reagent. Lwm txoj kev yog fluoroalkylation, uas fluoralkane reacts nrog benzaldehyde los tsim fluorobenzaldehyde. Txoj kev npaj tshwj xeeb tuaj yeem xaiv raws li koj xav tau.
Fluorobenzaldehyde muaj pungent tsw thiab tej zaum yuav khaus rau lub qhov muag, tawv nqaij, thiab ua pa ib ntsuj av. Cov iav tiv thaiv tsim nyog yuav tsum hnav thaum siv thiab yuav tsum zam kev sib cuag ncaj qha. Tsis txhob nqus cov pa roj los yog kev daws teeb meem. Nws yuav tsum tau ua nyob rau hauv ib qho chaw zoo-ventilated, deb ntawm hluav taws.
