Folasaga
2,4-Difluorobenzaldehyde o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i ona meatotino, fa'aoga, auala gaosi ma fa'amatalaga saogalemu:
Tulaga lelei:
- Fa'aaliga: Le lanu pe samasama vai.
- Solubility: solu i solu fa'aletino e pei ole ava malosi, ethers ma chlorinated hydrocarbons.
Fa'aaogā:
- 2,4-Difluorobenzaldehyde e masani ona faʻaaogaina e avea o se vaeluagalemu i le tuʻufaʻatasiga o isi faʻalapotopotoga faʻapitoa.
- Talosaga taua i le tuʻufaʻatasia o nisi photosensitizers.
Metotia:
2,4-difluorobenzaldehyde e masani ona saunia i auala nei:
- E mafai ona maua e ala i le taliina o le benzaldehyde ma le hydrogen fluoride, masani ile 40-50°C.
- E mafai foi ona saunia e ala i le tali atu i le chlorobenzaldehyde ma le hydrogen fluoride poʻo le fluorosilanes.
Fa'amatalaga Saogalemu:
- 2,4-Difluorobenzaldehyde atonu e faʻafefe i le paʻu, mata, ma le manava. O mea faigaluega puipuia talafeagai e pei o totigilima, mata tioata, ma le puipuiga o le manava e tatau ona ofuina pe a faʻaaoga pe tagofia.
- E tatau ona teu ese mai le afi ma le maualuga o le vevela, i totonu o se nofoaga malulu, mago, faʻalelei lelei, ma vavae ese mai mea faʻamaʻi ma mea malosi alkaline.
- Mata'ituina ma mulimulita'i fa'atonuga fa'agaioiga saogalemu talafeagai a'o le'i fa'aogaina.
