Folasaga

2,4-Dinitroaniline o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i ona meatotino, fa'aoga, auala gaosi ma fa'amatalaga saogalemu:

 

Tulaga lelei:

- 2,4-Dinitroaniline o se tioata samasama e le mafai ona solu i le vai.

- E maualuga lona tulaga fa'amumu ma pa, ma ua fa'avasegaina o mea pa.

- E mafai ona faʻaititia i amine faʻatasi e faʻavae malosi ma hydroxides.

 

Fa'aaogā:

- 2,4-Dinitroaniline e masani ona faʻaaogaina i le vailaʻau vailaʻau e avea o se mea mataʻutia mo mea pāpā ma mea pāpā.

- E mafai foi ona faʻaaogaina i le tuʻufaʻatasia o vali ma pigments, faʻapea foʻi ma se mea taua tele.

 

Metotia:

- O le sauniuniga o le 2,4-dinitroaniline e masani ona faia e le nitrification. p-nitroaniline fa'afefete fa'atasi ma le acid nitric concentrated e fausia ai le 2,4-dinitronitroaniline, ona fa'aitiitia ai lea o le fa'afefiloi ma le malosi malosi e maua ai le 2,4-dinitroaniline.

 

Fa'amatalaga Saogalemu:

- 2,4-Dinitroaniline o se vailaʻau sili ona pa ma e tatau ona taofia mai le mumū ma le vevela.

- O le a'afiaga o fete'ena'iga, a'afiaga, aloiafi, ma le fa'aeletise fa'alele e mana'omia le fa'atonutonuina lelei i le taimi o le tagofiaina, teuina, ma felauaiga.

- Fa'aaoga mea e puipui ai le tagata lava ia e pei o matatioata saogalemu ma totigilima puipui pe a fa'aoga. Afai e inuina, saili vave togafitiga faafomai.

 

Mulimuli i taimi uma faiga saogalemu talafeagai pe a faʻaaoga ma faʻaaogaina le 2,4-dinitroaniline, ma faʻaaoga ma le malamalama ma puipuiga talafeagai.
