Taw qhia
3,4-Difluorobenzaldehyde yog ib qho organic compound. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos mob: tsis muaj xim rau cov kua daj daj
- Solubility: soluble nyob rau hauv organic solvents, insoluble nyob rau hauv dej
- Kev sib hloov tshwj xeeb: approx. +9 °
- Tej zaum yuav decompose ntawm qhov kub thiab txias los tsim cov pa phem
Siv:
- Nws kuj yog siv los ua cov catalyst thiab reagent hauv cov organic synthesis cov tshuaj tiv thaiv
Txoj kev:
- Kev npaj ntawm 3,4-difluorobenzaldehyde tuaj yeem tau txais los ntawm kev ua haujlwm benzyl cawv nrog hydrofluoric acid thiab ua cov tshuaj hloov pauv raws li qhov tsim nyog.
Cov ntaub ntawv kev nyab xeeb:
- 3,4-Difluorobenzaldehyde ua rau khaus ntawm daim tawv nqaij thiab qhov muag, thiab kev sib cuag nrog daim tawv nqaij thiab qhov muag yuav tsum zam.
- Hnav cov hnab looj tes tiv thaiv, tsom iav, thiab lub tshuab ua pa thaum siv lossis tuav
- Tsis txhob nqus nws cov vapors thiab, yog tias tsim nyog, ua kom muaj cua zoo thaum ua haujlwm
- Khaws rau hauv qhov chaw txias, qhuav, deb ntawm qhov hluav taws kub thiab hluav taws kub
