Folasaga

2-Methylbutyric acid. O lo'o ta'ua i lalo se folasaga i meatotino, fa'aoga, metotia o sauniuniga ma fa'amatalaga saogalemu o le 2-methylbutyric acid:

 

Tulaga lelei:

Fa'aaliga: 2-methylbutyric acid o se vai e leai ni lanu po'o se tioata.

Density: approx. 0.92 g/cm³.

Solubility: 2-methylbutyric acid o lo'o solu se vaega ile vai.

 

Fa'aaogā:

E mafai foʻi ona faʻaaogaina e avea o se solvent mo resins, plasticizers mo palasitika, ma solvents mo paʻu.

2-Methylbutyric acid e mafai foʻi ona faʻaaogaina i le sauniuniga o faʻamaʻi ele uʻamea ma vali vali.

 

Metotia:

O auala sauniuni ole 2-methylbutyric acid e masani lava e pei ona taua i lalo:

E saunia e ala i le tali fa'ama'iina o le ethanol.

Saunia e ala i le tali fa'ama'iina o le 2-methacryrolen.

 

Fa'amatalaga Saogalemu:

2-Methylbutyric acid e ita ma e ono mafua ai le ita ma le erythema pe a paʻi i le paʻu, ma e tatau ona aloese mai le faʻafesoʻotaʻi tuusaʻo ma le paʻu.

O le inhalation o le 2-methylbutyric acid ausa e mafai ona mafua ai le faʻafefe o le faʻaʻi, faʻafefe manava, ma tale, ma e tatau ona gauai atu i le ea ma le puipuiga o le tagata lava ia.

A'o fa'aoga, e tatau ona 'alofia le fa'afeso'ota'i ma vaila'au malolosi ma mea fa'amumu e puipuia ai fa'alavelave mata'utia.

Pe a teuina ma taulimaina, e tatau ona aloese mai le vevesi tele ma le maualuga o le vevela.
