Folasaga

2-Methyl-4-nitroaniline o se faʻalapotopotoga faʻapitoa. O se samasama i le moli tioata malō ma lelei mautu. O loʻo taua i lalo se faʻamatalaga i meatotino, faʻaoga, metotia sauniuni ma faʻamatalaga saogalemu o le 2-methyl-4-nitroaniline:

 

Tulaga lelei:

- Fa'aaliga: Samasama i le moli tioata malo

- Soluble: Solu i nisi vaifofo fa'alenatura pei ole ethanol, chloroform ma le dimethyl sulfoxide.

 

Fa'aaogā:

- Alamanuia vailaʻau: 2-methyl-4-nitroaniline e mafai ona faʻaaogaina e avea o se vaeluaga i le faʻaogaina o meaola mo le faʻapipiʻiina o mea faʻapipiʻi e pei o vali, vailaʻau ma mea pāpā.

 

Metotia:

E tele auala e saunia ai le 2-methyl-4-nitroaniline:

- Nitrification tuusao: 2-methyl-4-aminoaniline e tali atu i le nitric acid concentrated e maua ai le 2-methyl-4-nitroaniline.

- Oxidation-nitrification: 2-methyl-4-bromoaniline e tali atu i le sili atu o le aniline peroxide ona faʻatasi ai lea ma le nitric acid concentrated e maua ai le 2-methyl-4-nitroaniline.

 

Fa'amatalaga Saogalemu:

- 2-Methyl-4-nitroaniline ose mea pāpā e ono mafua ai se pa pe a faʻaalia i le mumu poʻo le maualuga o le vevela.

- Pe a tagofia le 2-methyl-4-nitroaniline, fai mea e puipui ai oe lava e pei o totigilima puipui, mata tioata, ma ofu talaloa, ma ia mautinoa o loʻo faʻagaioia i se nofoaga e savili lelei.

- Aloese mai le fa'afeso'ota'i ma le pa'u, mata, ma le manava.

- Aloese mai le fa'afeso'ota'i ma mea e mu, oxidants, acids ma isi mea a'o teuina ma felauaiga.
