Taw qhia
M-fluorobenzaldehyde. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm m-fluorobenzaldehyde:
Zoo:
- Cov tsos mob: M-fluorobenzaldehyde yog cov kua tsis muaj xim lossis daj.
- Solubility: Soluble nyob rau hauv organic solvents xws li ethers, alcohols thiab ether alcohols.
Siv:
- High-efficiency insecticides: M-fluorobenzaldehyde, ua ib qho nruab nrab ntawm cov organic synthesis, yog siv dav hauv kev ua liaj ua teb los npaj cov tshuaj tua kab uas muaj txiaj ntsig zoo, xws li tshuaj tua kab CFOFLUOROETHYLENE lossis lwm yam khoom siv tshuaj tua kab.
- Kev siv tshuaj lom neeg: M-fluorobenzaldehyde feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis thiab tuaj yeem siv los npaj lwm cov tebchaw, xws li m-fluorophenyl oxalate thiab camphor ethanol.
Txoj kev:
- Muaj ob txoj kev npaj tseem ceeb rau m-fluorobenzaldehyde: fluoride method thiab fluorination method. Ntawm lawv, txoj kev fluoride yog tau los ntawm reacting m-fluorophenylmagnesium fluoride nrog formaldehyde; Txoj kev fluorination yog tau los ntawm hydrolysis ntawm p-toluene thiab antimony trichloride nyob rau hauv ib qho chaw chlorine.
Cov ntaub ntawv kev nyab xeeb:
- Nws yog ib qho tseem ceeb heev uas m-fluorobenzaldehyde yog ib qho tshuaj lom thiab yuav tsum tau ua haujlwm hauv qhov cua kom zoo thiab cov cuab yeej tiv thaiv tus kheej tsim nyog yuav tsum hnav.
- Thaum siv lossis khaws cia, tsis txhob sib xyaw nrog cov oxidants muaj zog, cawv thiab lwm yam khoom kom tsis txhob muaj kev phom sij txaus ntshai.
- Khaws lub thawv kom nruj thiab kom deb ntawm qhov hluav taws kub thiab qhov chaw kub thaum khaws cia.
