Folasaga
4,5-Dimethylthiazole o se faʻalapotopotoga faʻapitoa. O nisi nei o ona meatotino, fa'aoga, metotia gaosiga, ma fa'amatalaga saogalemu:
Tulaga lelei:
- Fa'aaliga: Sua e leai ni lanu po'o se tioata tioata.
- Solubility: Solu i le tele o solu fa'aola pei ole ava malosi, eter ma ketones.
- Tulaga mautu: E fai si mautu ile vevela ole potu.
Fa'aaogā:
- E mafai foʻi ona faʻaaogaina e fai ma faʻavave paʻu ma faʻamaʻi paʻu vulcanizing e faʻaleleia ai mea faʻainisinia o le paʻu.
Metotia:
- 4,5-Dimethylthiazole e mafai ona gaosia e ala ile tali ole dimethyl sodium dithiolate ma le 2-bromoacetone.
- Fa'atusa o tali: 2-bromoacetone + dimethyl dithiolate → 4,5-dimethylthiazole + sodium bromide.
Fa'amatalaga Saogalemu:
- 4,5-Dimethylthiazole ose fa'aputuga fa'aola ma e tatau ona 'alo'ese fa'atasi ai ma faiga talafeagai.
- Totigilima puipui, mata tioata ma ofu e mana'omia a'o fa'aoga.
- Aloese mai le manavaina o ana ausa ma faʻamautinoa le faʻaogaina i totonu o se siosiomaga faʻaleleia lelei.
- Pe a fa'afuase'i ona sausau mata, fufulu vave i le tele o vai ma saili vave togafitiga faafoma'i.
- Teu le 4,5-dimethylthiazole i se nofoaga malulu, matutu mamao ese mai mea faʻamaʻi ma vailaʻau malolosi.
