Folasaga
2,4-Dimethyl-5-acetylthiazole o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i meatotino, fa'aoga, metotia sauniuni ma fa'amatalaga saogalemu o lenei fa'apotopotoga:
Tulaga lelei:
- Faʻaaliga: 2,4-Dimethyl-5-acetylthiazole o se lanu e leai se lanu i le malamalama samasama tioata poʻo le paʻu malosi.
- Solubility: E solu i le tele o solu faʻaola pei ole ethanol, eter ma acetone, ma soluble teisi i le vai.
Fa'aaogā:
- Vailaau faalafua: 2,4-dimethyl-5-acetylthiazole ose iniseti lautele o alaleo e fa'aaogaina e pulea ai fa'ama'i fa'ato'aga e pei ole mogamoga laula'au ma anufe kapisi.
Metotia:
- 2,4-Dimethyl-5-acetylthiazole e masani lava ona saunia e ala i le tali atu i le 2,4-dimethylthiazole faʻatasi ai ma se mea faʻapipiʻi e pei ole acetyl chloride. O le tali e faia i totonu o se solvent talafeagai, faʻavevela ma faʻavevesi mo se vaitaimi, ona faʻamamaina lea e ala i le tioata poʻo le suction filtration.
Fa'amatalaga Saogalemu:
- Fa'aaoga mea e puipui ai le tagata lava ia e pei o totigilima falesu'esu'e ma matatioata puipui a'o fa'agaioiga fale gaosimea.
- Aloese mai le pa'i o le pa'u ma le manavaina o le pefu, asu, po'o kasa mai le fa'aputuga.
- Pe a teu, teu i totonu o se atigipusa malulu, mamao ese mai afi ma oxidants.
- I le taimi o le faʻaaogaina, e tatau ona mulimulitaʻi i faʻatonuga talafeagai o le faʻaogaina o le saogalemu ma faia vave fesoasoani fesoasoani muamua pe a tupu se faʻalavelave. I le tulaga o le manava fa'afuase'i po'o le 'ai fa'afuase'i, saili vave togafitiga faafoma'i.
