Folasaga puupuu
O le 4-Chloro-2-fluorobenzoic acid o se vailaʻau faʻapitoa. O lo'o ta'ua i lalo se folasaga i ona meatotino, fa'aoga, auala gaosi ma fa'amatalaga saogalemu:
Tulaga lelei:
4-Chloro-2-fluorobenzoic acid o se tioata malosi, e masani ona leai ni lanu pe samasama tioata. E le fa'afefete i le vevela o le potu. E i ai se manogi manogi ma e mafai ona faʻamavaeina i soʻo faʻalagona pei ole methanol, ethanol, methylene chloride, ma isi.
Fa'aaogā:
4-Chloro-2-fluorobenzoic acid o loʻo i ai le tele o faʻaoga i totonu o le vailaʻau vailaʻau. E masani ona faʻaaogaina e avea o se mea amata poʻo se vaeluaga i le faʻaogaina o meaola. E mafai foi ona faʻaaogaina e fai ma meaʻai mo catalysts ma mea faʻaeletoroni.
Metotia:
4-Chloro-2-fluorobenzoic acid e mafai ona maua ile chlorination ole p-fluorobenzoic acid. I le tulaga lautele, o le hydrogen chloride poʻo le chlorous acid e mafai ona faʻafefe i le thionyl chloride poʻo le sulfinyl chloride i lalo o tulaga faʻamaʻi, sosoo ai ma le tali atu i le hydrogen fluoride e maua ai le 4-chloro-2-fluorobenzoic acid.
Fa'amatalaga Saogalemu:
O puipuiga nei e tatau ona faia pe a tagofia le 4-chloro-2-fluorobenzoic acid: aloese mai le faʻafesoʻotaʻi ma le paʻu ma mata, ma faʻalogo lelei i faiga puipuia e pei o le faia o mata tioata ma totigilima. E tatau ona faia i totonu o se nofoaga e faʻafefe lelei e puipuia ai le manava pe foloina. Aloese mai le fa'afeso'ota'i ma mea e mu ma 'alo 'ese mai mu matala po'o le vevela maualuga. E tatau ona faʻamaufaʻailogaina lelei pe a faʻaaogaina pe teuina ma mamao ese mai acids, bases, ma oxidants. A tupu se liki, e tatau ona faia ni fa'alavelave fa'afuase'i talafeagai, e pei o le mitiia o le vai i se desiccant po'o le fa'amamāina i se vaila'au talafeagai.
