Folasaga
O le 5-fluoro-2-nitrobenzoic acid(5-fluoro-2-nitrobenzoic acid) o se fa'alapotopotoga fa'alenatura ma le fua fa'atatau C7H4FNO4. O lo'o taua i lalo se fa'amatalaga o lona natura, fa'aoga, sauniuniga ma fa'amatalaga saogalemu:
natura:
-Fa'aaliga: 5-fluoro-2-nitrobenzoic acid o le pa'epa'e po'o le pa'epa'e pa'epa'e tioata.
- Liu liusuavai: E tusa o le 172°C.
-Solubility: Solu teisi i le vai, soluble i nisi solvents organic pei ole ava malosi ma esters.
Fa'aaogā:
-Kemisi faʻapipiʻi: 5-fluoro-2-nitrobenzoic acid o se faʻaoga masani faʻaoga faʻapitoa, lea e mafai ona faʻaaogaina e faʻapipiʻi ai isi mea faʻapipiʻi, e pei o vailaʻau, vailaau faʻasaina ma vali.
- Faamoemoega o suʻesuʻega faʻasaienisi: Ona o lona fausaga o loʻo i ai vaega o le fluorine ma le nitro, o le 5-fluoro-2-nitrobenzoic acid o loʻo i ai mea faʻapitoa faʻapitoa ma e mafai ona faʻaaogaina mo suʻesuʻega ma suʻega suʻesuʻe.
Metotia:
O le auala sauniuni o le 5-fluoro-2-nitrobenzoic acid e masani lava ona maua i le fluorination reaction o le 2-nitrobenzoic acid.
1. Muamua, o le 2-nitrobenzoic acid e tali atu i se vailaʻau faʻafefe (e pei o le hydrogen fluoride poʻo le sodium fluoride).
2. Ina ua maeʻa le tali, na maua le 5-fluoro-2-nitrobenzoic acid product.
E tatau ona maitauina i le taimi o le sauniuniga, e tatau ona faʻaogaina tulaga faʻataʻitaʻiga talafeagai ma faiga saogalemu e faʻamautinoa ai le saogalemu o le suʻega.
Fa'amatalaga Saogalemu:
- O le 5-fluoro-2-nitrobenzoic acid e manatu o se mea e saogalemu i lalo o tulaga lautele, ae e manaʻomia lava ona taulimaina ma le faʻaeteete ma mulimuli i faiga faʻataʻitaʻiga talafeagai.
-I le faʻafesoʻotaʻi ma lenei mea, faʻafesoʻotaʻi saʻo le paʻu ma le manavaina o lona pefu e tatau ona aloese.
-I le faʻaogaina ma le teuina o faʻagasologa, faʻamolemole puipuia lelei mea faigaluega falesuesue, ma tausisia taʻiala talafeagai mo le saogalemu.
-A tupu se fa'alavelave po'o le masalomia o le 'ona, saili vave togafitiga fa'afoma'i ma aumai le pepa fa'amaumauga o le saogalemu.
