Folasaga

formic acid) ose vai e le lanu ma se manogi manogi. O mea taua ia o le formic acid:

 

Mea fa'aletino: Formic acid e sili ona solu ma solu i le vai ma le tele o solu fa'aletino.

 

O mea tau vaila'au: Formic acid ose mea fa'aitiitiga e faigofie ona fa'ama'iina i le kaponi ma vai. O le tuufaatasiga e tali atu i se faavae malosi e maua ai le formate.

 

Ole fa'aoga autu ole formic acid e fa'apea:

 

I le avea o se vailaau faʻamaʻi ma faʻasao, e mafai ona faʻaaogaina le formic acid i le sauniuniga o vali ma paʻu.

 

E mafai fo'i ona fa'aogaina le fomic acid e fai ma mea e fa'afefe ai le aisa ma fa'ama'i miti.

 

E lua auala autu e saunia ai le formic acid:

 

Auala fa'aleaganu'u: Fa'amama le auala e maua mai ai le acid formic e ala i le fa'ama'iina o fafie.

 

Metotia fa'aonaponei: formic acid e saunia e le methanol oxidation.

 

O puipuiga mo le fa'aogaina saogalemu o le formic acid e fa'apea:

 

O le formic acid e iai sona manogi manogi ma mea e pala, o lea e tatau ai ona e fai totigilima ma mata tioata pe a fa'aaogaina.

 

Aloese mai le manavaina o le ausa formic acid poʻo le pefu, ma faʻamautinoa lelei le faʻafefe pe a faʻaaoga.

 

Formic acid e mafai ona mafua ai le mu ma e tatau ona teu ese mai afi ma mea e mu.
