Meatotino Faaletino ma Vailaau Suavai e le lanu. Fa'asao 169-171 ℃,61 ℃(1.33kPa). Metotia Sauniuniga: Ole vaifofo o le sodium methyl mercaptan-anhydrous ethanol e fa'avevela e fa'apuna, taofi le fa'avevela, ae fa'aopoopo le chloroethanol i lalo ole fa'aoso i totonu ole 2H. O le fa'afefiloiga tali sa fa'atumauina, fa'ataga e tu mo le mālūlū, ma fa'amama le sodium chloride. O le filtrate na vaevaeina i lalo o le faʻaitiitia o le mamafa e aoina ai se vaega 68-70 ° C. (2.67kPa) e maua ai le 2-methylthioethanol i se fua o le 74% -82%. Fa'amoemoega: vaeluagalemu i le tu'ufa'atasiga.

Folasaga

2-Methylthioethanol, lea e taʻua foi o le 2-methylthioethanol, 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-Methylthioethanol ose vai e leai se lanu i se vai samasama.

- Sogisogi: E malosi lona manogi ole hydrogen sulfide.

- Solubility: Solu i le vai ma nisi solu fa'aletino e pei ole ava malosi ma ethers.

- Meatotino: E maaleale i le ea ma e mafai ona faʻamaʻiina i le disulfide, lea e faigofie ona faʻafefe.

 

Fa'aaogā:

- Fa'asologa o vaila'au: 2-methylthioethanol e mafai ona fa'aogaina e fai ma mea fa'avauvau i le fa'aogaina o meaola.

- Detergent: E mafai ona faʻaaogaina e fai ma mea faʻafefe ma faʻamama i le sauniuniga o vailaʻau.

- Fa'asao le afi o le ava malosi: 2-methylthioethanol e mafai ona fa'aogaina e fai ma mea e fa'afefe ai le afi.

 

Metotia:

2-Methylthioethanol e mafai ona saunia e:

- Thioethanol e faia e ala ile tali ile methyl chloride.

- O le Ethiohydrazine e fa'atupu ile tali atu ile ethanol.

 

Fa'amatalaga Saogalemu:

- 2-Methylthioethanol e manogi leaga ma e ono afaina ai mata ma pa'u pe a tago i ai.

- Pe a manava, e mafai ona mafua ai le manava manava ma le faʻanoanoa o le fatafata.

- O le foloina po'o le 'aina tele e ono mafua ai le 'ona, ma mafua ai le tiga ole manava.

- Fa'aaoga mea faigaluega puipuia e pei o totigilima ma matatioata saogalemu pe a fa'aaoga.

- A fa'agaoioi, 'alo 'ese mai afi matala ma nofoaga e maualuga le vevela e 'alofia ai le fa'amumu.
