Folasaga

2-nitroaniline, e lauiloa foi o le O-nitroaniline, o se faʻalapotopotoga faʻapitoa. O loʻo taua i lalo se faʻamatalaga i meatotino, faʻaoga, metotia sauniuni ma faʻamatalaga saogalemu o le 2-nitroaniline.

 

Tulaga lelei:

- Faʻaaliga: 2-nitroaniline o se tioata samasama poʻo se paʻu tioata.

- Solubility: 2-nitroaniline e solu i le ethanol, eter ma benzene, ma solute laitiiti i le vai.

 

Fa'aaogā:

- Gaosiga o vali: 2-nitroaniline e mafai ona faʻaaogaina i le tuʻufaʻatasia o mea faʻalanu, pei o le saunia o le lanu samasama aniline.

- Pa'u: 2-nitroaniline o lo'o i ai mea pāpā ma e mafai ona fa'aaogaina e fai ma mea mata mo mea pāpā ma pyrotechnics.

 

Metotia:

- 2-nitroaniline e mafai ona saunia e ala i le tali atu o le aniline ma le nitric acid. O tulaga e tali atu ai e masani lava ona faia i le maualalo o le vevela ma o le sulfuric acid e faʻaaogaina e fai ma faʻamalosi.

- Fa'atusa o tali: C6H5NH2 + HNO3 -> C6H6N2O2 + H2O

 

Fa'amatalaga Saogalemu:

- 2-Nitroaniline ose mea pāpā e ono mafua ona o le faʻaalia i le afi poʻo le maualuga o le vevela. E tatau ona 'alo'ese mai le mumū o le afi, puna vevela, aloiafi eletise, ma isi.

- Fai matatioata puipui ma totigilima pe a fa'agaioiga e 'alofia ai le manavaina o le pefu po'o le pa'i i le pa'u, ma aloese mai le 'ai fa'afuase'i.

- Pe a fa'afeso'ota'i ma le 2-nitroaniline, fufulu vave i le tele o vai ma sa'ili fa'afoma'i mo togafitiga.
