Mawu Oyamba
2,4-Difluorobenzaldehyde ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:
Ubwino:
- Maonekedwe: Madzi opanda mtundu kapena achikasu.
- Kusungunuka: kusungunuka mu zosungunulira organic monga ma alcohols, ethers ndi ma chlorinated hydrocarbons.
Gwiritsani ntchito:
- 2,4-Difluorobenzaldehyde nthawi zambiri amagwiritsidwa ntchito ngati wapakatikati pakuphatikizika kwazinthu zina.
- Ntchito zofunika pakuphatikiza kwa ma photosensitizers ena.
Njira:
2,4-difluorobenzaldehyde nthawi zambiri imakonzedwa ndi njira izi:
- Itha kupezeka pochita benzaldehyde ndi hydrogen fluoride, nthawi zambiri pa 40-50°C.
- Itha kukonzedwanso pochita ndi chlorobenzaldehyde yokhala ndi hydrogen fluoride kapena fluorosilanes.
Zambiri Zachitetezo:
- 2,4-Difluorobenzaldehyde ikhoza kukwiyitsa khungu, maso, ndi kupuma. Zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi chitetezo cha kupuma ziyenera kuvala mukamagwiritsa ntchito kapena pogwira.
- Ziyenera kusungidwa kutali ndi moto ndi kutentha kwambiri, pamalo ozizira, owuma, odutsa mpweya wabwino, komanso mosiyana ndi zowonjezera zowonjezera komanso zamchere zamphamvu.
- Yang'anirani ndikutsata njira zoyendetsera chitetezo mwatsatanetsatane musanagwiritse ntchito.
