-E mafai foi ona faʻaaogaina e avea o se mea faʻapipiʻi faʻapipiʻi mo vailaʻau faʻalaʻau.
Metotia:
I se tulaga lautele, 4-(Trifluoromethyl) phenylhydrazine hydrochloride e mafai ona saunia i laasaga nei:
1. O le 4-Nitrotoluene e tali atu i le trifluoromethanesulfonic acid e maua ai le 4-trifluoromethyltoluene.
2. O le 4-Trifluoromethyltoluene e tali atu i le hydrazine e gaosia ai le 4-trifluoromethylphenylhydrazine.
3. Mulimuli ane, o le 4-trifluoromethylphenylhydrazine e tali atu i le hydrochloric acid e maua ai le 4-(Trifluoromethyl) phenol hydrochloride.
Fa'amatalaga Saogalemu:
- 4-(Trifluoromethyl)phenylhydrazine hydrochloride ose vailaʻau e manaʻomia le mulimulitaʻia o faʻataʻitaʻiga talafeagai mo le saogalemu ma faʻatumauina faiga talafeagai mo le saogalemu o falesuesue.
- Fa'aaoga mea e puipui ai le tagata lava ia e pei o totigilima a le fale suesue, mata tioata, ma isi pe a tago i le fa'afu.
- Aloese mai le manavaina o lona pefu poʻo le faʻafesoʻotaʻi ma le paʻu, mata ma lavalava e puipuia ai le ita poʻo le manuʻa.
- Aloese mai le faʻafesoʻotaʻi ma vailaʻau faʻamaʻi ma vailaʻau malosi i le taimi o le teuina ma le taulimaina e aloese ai mai le faʻaalia.
-Afai e folo pe manava, saili vave togafitiga faafomai. Afai e pa'i le pa'u po'o mata, fufulu ile vai tele mo le itiiti ifo ile 15 minute ma saili se foma'i.
