Folasaga

Trans-cinnamic acid ose mea fa'aola. O loʻo i ai i foliga o tioata paʻepaʻe poʻo paʻu tioata.

 

Trans-cinnamic acid e malo i le vevela o le potu ma e mafai ona solo i le ava malosi, ethers ma solvents acid, ma solu teisi i le vai. E iai sona manogi manogi fa'apitoa.

 

Trans-cinnamic acid e tele lona fa'aoga.

 

Ole auala sauniuni ole trans-cinnamic acid e mafai ona maua ile tali ole benzaldehyde ma le acrylic acid. E masani ona fa'aogaina auala sauniuni e aofia ai fa'ama'i fa'ama'i, fa'ama'i fa'ama'i fa'ama'i ma tali fa'ama'i fa'ama'i.

Mo se faʻataʻitaʻiga, aloese mai le faʻafesoʻotaʻi saʻo ma le paʻu ma mata e aloese ai mai le ita ma le mumū. Pe a fa'agaioi, e tatau ona fa'aoga meafaigaluega puipui talafeagai, e pei o totigilima falesuesue, matatioata puipui, ma isi. Trans-cinnamic acid e tatau ona teuina lelei ina ia aloese mai le fa'afeso'ota'i ma puna fa'amumu ma fa'ama'i e puipuia ai fa'alavelave fa'afuase'i o le afi ma le pa. A'o fa'aoga, fa'agaoioi e tusa ai ma le fa'agasologa sa'o ma fa'atonuga fa'agaioiga ina ia mautinoa le saogalemu.
