Folasaga

2-Amino-4-nitrophenol o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i lona natura, fa'aoga, auala sauniuni ma fa'amatalaga saogalemu:

 

Tulaga lelei:

2-Amino-4-nitrophenol o se mea mautu ma tioata samasama i foliga. E maualalo le solubility i le vevela o le potu, e soluble i solvents organic pei ole eter ma benzene, ma soluble teisi i le vai. E malosi fa'asa'o ma malosi fa'ama'i.

 

Fa'aaogā:

2-Amino-4-nitrophenol e masani ona faʻaaogaina e avea o se mea mataʻutia mo vali ma lanu. E mafai ona fa'aoga e saunia ai vali e foliga samasama po'o moli, ma e mafai fo'i ona fa'aoga e saunia ai lanu i lanu ma vali.

 

Metotia:

O le tuʻufaʻatasiga o le 2-amino-4-nitrophenol e mafai ona maua e ala i le faʻaalia o le phenol ma le nitric acid e fausia ai le p-nitrophenol, ona faʻaalia lea i le vai ammonia e fausia ai le 2-amino-4-nitrophenol. O le auala faʻapitoa faʻatasi ma tulaga faʻaalia o le a eseese, ma e mafai ona filifilia le auala faʻapipiʻi talafeagai e tusa ai ma manaʻoga.

 

Fa'amatalaga Saogalemu:

O le 2-Amino-4-nitrophenol ose mea faʻafefe ma oona, ma o le faʻaalia poʻo le inuina o lona pefu e ono mafua ai le faʻafefe i mata, paʻu, ma le manava. E tatau ona ofuina ni mea e puipui ai le tagata lava ia pe a fa'aaoga pe tagofia ma e tatau ona 'alofia le fa'afeso'ota'i sa'o. E mafai foi ona afaina ai le siosiomaga, ma otaota e tatau ona lafoaʻi lelei ma e tatau ona mulimulitaʻia faiga faʻaoga saogalemu.
