Folasaga
4-Nitro-3-trifluoromethylaniline, e lauiloa foi o le TNB (Trinitrofluoromethylaniline), 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:
- Fa'aaliga: Pa'epa'e i tioata samasama malamalama po'o pa'u
- Solubility: soluble teisi i le vai, soluble i solu faʻaola pei ole ethanol, acetone, ma isi.
- Tulaga mautu: E mautu i le malamalama, vevela ma le ea, ae faigofie ile susu ma pa.
Fa'aaogā:
- 4-Nitro-3-trifluoromethylaniline e masani ona faʻaaogaina e avea o se vaega o mea amata ma mea pāpā, mo se faʻataʻitaʻiga, e mafai ona faʻaaogaina e suitulaga i le TNT (tinitrotoluene). E maualuga le malosi o le pa ma le mautu i le fanua o mea pāpā.
Metotia:
- Mai le aniline, o le trifluoromethanesulfonic acid e muamua ona tali atu i le bromide cuprous e fausia ai le trifluoromethylaniline. Ona, faʻafeiloaʻi le trifluoromethylaniline i le nitric acid, faʻaopoopo le nitrobenzene, ma a maeʻa togafitiga o le nitrite acid, e iu lava ina maua le 4-nitro-3-trifluoromethylaniline.
Fa'amatalaga Saogalemu:
- 4-Nitro-3-trifluoromethylaniline o se mea paʻu ma e manatu e pa ma e tatau ona faʻaaoga ma le faʻaeteete.
- Pe a tagofia ma teuina, aloese mai le faʻaosoina o soʻo se afi poʻo aloiafi eletise.
- Aloese mai le fa'afeso'ota'i ma mea e mu, vaila'au fa'ama'i ma mea alkaline e ono fa'atupu ai ni fa'alavelave mata'utia.
- O le manava, fa'ai, po'o le fa'afeso'ota'i i le pa'u ma mata e ono iai ni a'afiaga leaga, e mana'omia ai le ofuina o mea e puipui ai le tagata lava ia pe a fa'agaioi.
