methyl 2H-1 2 3-triazole-4-carboxylate（CAS# 4967-77-5)
Folasaga
Methyl 1,2,3-triazole-4-carboxylic acid 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:
Methyl 1,2,3-triazole-4-carboxylic acid o se vai lanu samasama e leai se lanu ma se manogi malosi. E solu i solu fa'aola pei ole ethanol ma dimethylformamide. E fai si mautu i le vevela o le potu, ae pala i le maualuga o le vevela poʻo lalo o le malamalama.
Fa'aoga: E mafai fo'i ona fa'aogaina e fai ma fa'atonuga o le tuputupu a'e o la'au ma se vaega o mea fa'aata.
Metotia:
O se metotia masani sauniuni mo le methyl 1,2,3-triazole-4-carboxylic acid e maua e ala i le tali atu i le phenylenediamine ma le formic anhydride i lalo o tulaga alkaline. O le faagasologa o sauniuniga faapitoa e faapea:
1) Fa'aopoopo le phenylenediamine ma le formic anhydride i se vaifofo alkaline, e masani ona fa'aaoga le sodium hydroxide po'o le sodium carbonate e fai ma sui ole alkaline;
2) I se vevela talafeagai, o le tali e faia mo le tele o itula e faʻaalia atoatoa ai le tali;
3) O le oloa e faʻamama ma faʻamamāina e ala i le faʻamaʻiina e maua ai le methyl 1,2,3-triazole-4-carboxylate.
Fa'amatalaga Saogalemu:
Methyl 1,2,3-triazole-4-carboxylic acid e sili ona ita ma pala, ma faʻafesoʻotaʻi ma le paʻu, mata, poʻo le manavaina o ona ausa e ono mafua ai le ita poʻo isi faʻafitauli faʻalesoifua maloloina. O mea faigaluega puipuia o le tagata lava ia (PPE) talafeagai, e aofia ai totigilima, mata puipui, ma mea e puipuia ai le manava, e tatau ona ofuina pe a faʻaaogaina pe tagofia. E tatau ona fa'agaioia i totonu o se nofoaga e fa'afefe lelei ma aloese mai le fa'afeso'ota'i ma ni mea fa'ama'i malolosi po'o mea e mu. A fa'afuase'i ona fa'afeso'ota'i, fufulu vave i le tele o vai ma saili vave togafitiga faafoma'i.
