Folasaga
3,5-Dichloro-4-hydroxybenzoic acid 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:
- Faʻaaliga: 3,5-Dichloro-4-hydroxybenzoic acid o se paʻu tioata paʻepaʻe e leai se lanu.
- Solubility: E solu i nisi solvents organic pei ole ava malosi ma ethers, ae e le mafai ona solu i le vai.
Fa'aaogā:
Metotia:
- 3,5-Dichloro-4-hydroxybenzoic acid e mafai ona maua ile chlorination ole parahydroxybenzoic acid. O le auala faʻapitoa o le tali atu o le hydroxybenzoic acid ma le thionyl chloride e sui ai le hydrogen atom i luga o le hydroxyl group ma chlorine atoms i lalo o tulaga faʻafefe e ala i le suitulaga o ions chloride.
Fa'amatalaga Saogalemu:
- Aafiaga i le soifua maloloina o tagata: 3,5-dichloro-4-hydroxybenzoic acid e leai se afaina tele i le soifua maloloina o tagata i lalo o tulaga lautele o le faʻaaogaina.
- Aloese mai le fa'afeso'ota'i: Pe a tagofia le mea lea, 'alo'ese le fa'afeso'ota'i sa'o i le va o le pa'u ma mata ma ia mautinoa e fa'agaioi i se nofoaga e fa'aalili lelei.
- Puipuiga o le teuina: E tatau ona teuina i se nofoaga mago, malulu, ma fa'alili, mamao ese mai afi ma mu.
