| Fa'ailoga Mata'utia | Xi – Irita |
| Tulaga lamatia | R36/37/38 – Fa'aitaita'i i mata, faiga manava ma le pa'u. R5 – O le vevela e ono tupu ai se pa |
| Fa'amatalaga Saogalemu | S26 – Pe a pa'i i mata, fufulu vave i le tele o vai ma saili fautuaga fa'afoma'i. S37/39 – Fai totigilima talafeagai ma le puipuiga o mata/mata |
Folasaga
2-Nitrophenylhydrazine(2-Nitrophenylhydrazine) ose fa'aputuga fa'aola fa'atasi ma le fua fa'atatau kemikolo C6H6N4O2. O se pauta tioata samasama.
E uiga i le natura:
-Fa'aaliga: Pa'u tioata samasama
- Liu liusuavai: 117-120 ° C
-Tausaga: 343 ° C (vala'aina)
-Solubility: Soluble teisi i le vai, soluble i solu faʻaola pei ole ethanol, acetone ma dichloromethane
Fa'aaogā:
2-Nitrophenylhydrazine o se faʻasologa faʻasolosolo faʻasolosolo, faʻaaogaina lautele i le sauniuniga o le tele o vailaʻau faʻasolosolo ma vali. E mafai ona fa'aogaina i le tu'ufa'atasiga o mea fa'apipi'i carbamic bis (2-Nitrophenylhydrazine) e fai ma vaila'au va'ava'ai ma mea e fa'alumaina ai le mu.
Metotia:
2-Nitrophenylhydrazine e mafai ona saunia e ala i le tali atu i le 2-Nitrophenylhydrazine acid ma se sui faʻaitiitia talafeagai, e pei o le sulfite poʻo le hydride. O tulaga e tali atu ai e mafai ona fa'amautu i luga o fa'avae i lea mataupu.
Fa'amatalaga Saogalemu:
2-Nitrophenylhydrazine e ono tula'i mai se lamatiaga o le soifua maloloina pe a fa'aalia ma manava. E fa'aitaita ma e ono fa'atupu ai le fa'afefe o le manava, fa'afefe mata ma le pa'u. E le gata i lea, o le 2-Nitrophenylhydrazine o loʻo manatu foi e ono mafai ona faʻamaʻi ma faʻamaʻi. O lea, ia fa'aeteete ma faia ni puipuiga talafeagai, e pei o le ofuina o totigilima puipui, matatioata saogalemu ma mea e puipuia ai le manava. Pe a teuina ma taulimaina le faʻaogaina, e manaʻomia le mataʻituina o auala saogalemu.
