Folasaga
2-Ethyl-3-methylpyrazine o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i ona meatotino, fa'aoga, auala gaosi ma fa'amatalaga saogalemu:
Tulaga lelei:
- Fa'aaliga: 2-ethyl-3-methylpyrazine o lo'o i totonu o se vai e leai ni lanu po'o se tioata malosi.
- Solubility: E maualalo le solubility i le vai, ae mafai ona soluble i soluble organic.
- Faʻamautu: O se faʻamautu mautu, ae o le faʻafesoʻotaʻi ma vailaʻau malolosi ma vailaʻau malolosi e tatau ona aloese.
Fa'aaogā:
- 2-Ethyl-3-methylpyrazine ose faʻaaogaina masani ma faʻaaogaina foi e avea o se vaeluaga i le faʻaogaina o vailaʻau.
Metotia:
2-Ethyl-3-methylpyrazine e mafai ona saunia i auala nei:
- E tali muamua le Ethyl bromide i le pyrazine e maua ai le 2-ethylpyrazine i lalo ole tulaga alkaline.
- Mulimuli ane, o le 2-ethylpyrazine e tali atu i le methyl bromide e maua ai le 2-ethyl-3-methylpyrazine mulimuli.
Fa'amatalaga Saogalemu:
- 2-Ethyl-3-methylpyrazine e masani ona manatu e maualalo le oona, ae tatau ona mulimulitaʻia tulafono saogalemu.
- Aloese mai le manava, fa'afeso'ota'i i le pa'u ma mata, ma fai mea e puipui ai le tagata lava ia e pei o totigilima, mata tioata, ma talipupuni mata.
- Pe a teuina ma taulimaina, ia tuʻu ese mai faʻapogai faʻamumu ma faʻamaʻi faʻamaʻi ina ia aloese mai le lamatiaga o le afi ma le pa.
- Va'ai i tusitusiga talafeagai mo le saogalemu ma le pepa o fa'amatalaga saogalemu o lo'o tu'uina atu e le fa'atau oloa mo fa'amatalaga sili atu ma sa'o le saogalemu.
