Folasaga

4-Methylvaleric acid, lea e taʻua foi o le isovaleric acid, o se faʻalapotopotoga faʻapitoa. O lo'o taua i lalo se fa'amatalaga pu'upu'u i lona natura, fa'aoga, auala sauniuni ma fa'amatalaga saogalemu:

 

Tulaga lelei:

- Fa'aaliga: Suavai e leai ni lanu

- Solubility: Solu i le vai ma solu fa'aletino

- Sogisogi: E iai le manogi oona e pei o le acetic acid

 

Fa'aaogā:

- I totonu o le gaosiga o mea manogi, e mafai ona faʻaaogaina e faʻapipiʻi ai meaʻai o fualaau 'aina, fualaau faisua ma mea faʻafefete.

- I totonu o pisinisi faʻapipiʻi, e faʻaaogaina e avea o se solvent ma plasticizer.

 

Metotia:

- 4-Methylpentanoic acid e mafai ona saunia e ala i le tali atu o le isovaleric acid ma le carbon monoxide i luma o le malamalama.

- E masani ona faʻaaogaina mea faʻapitoa e pei ole alumininic acid poʻo le potassium carbonate i le tali.

 

Fa'amatalaga Saogalemu:

- 4-Methylpentanoic acid o se vai e mu ma e tatau ona taofia mai le mumū ma le vevela maualuga.

- Fa'aaoga mea e puipui ai, e pei o totigilima ma mata, pe a fa'aoga.

- 'Alo'ese mai le manava, 'ai, pe fa'afeso'ota'i ma pa'u ma mata a'o tagofia.
