Folasaga

Aminobenzene sulfonic acid, e taʻua foi o le sulfamine phenol, o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i meatotino, fa'aoga, metotia o sauniuniga ma fa'amatalaga saogalemu o le p-aminobenzene sulfonic acid:

 

Tulaga lelei:

Aminobenzenesulfonic acid o se pa'epa'e tioata pa'epa'e e leai se manogi ma solu i le vai ma le ethanol.

 

Fa'aaogāina: E mafai fo'i ona fa'aoga i le tu'ufa'atasiga o nisi o vali ma vaila'au fa'ama'i.

 

Metotia:

Aminobenzenesulfonic acid e mafai ona maua e ala i le tali atu o le benzenesulfonyl chloride ma le aniline. Muamua, o le aniline ma le alkali e faʻapipiʻiina e fausia ai le m-aminobenzene sulfonic acid, ona maua ai lea o le aminobenzene sulfonic acid e ala i le acylation reaction.

 

Fa'amatalaga Saogalemu:

E ese mai i ona aafiaga ita i mata, paʻu, ma le manava, aminobenzene sulfonic acid e leʻi faʻailoa manino mai e oona pe mataʻutia. Pe a faʻaaoga pe faʻaaogaina le aminobenzene sulfonic acid, faʻatumauina lelei le ea, aloese mai le faʻafesoʻotaʻi ma mata ma le paʻu, ma fai mea puipui pe a manaʻomia. Afai na fa'afuase'i ona 'ai pe pa'i atu i ai, saili vave togafitiga faafoma'i. Pe a teuina ma faʻasaoina, e tatau ona teuina i se nofoaga matutu, malulu, mamao ese mai le afi ma isi mea e mu.
