Folasaga

Tert-butylphenol o se fa'aputu fa'aola. O lo'o ta'ua i lalo se fa'amatalaga i meatotino, fa'aoga, metotia o sauniuniga ma fa'amatalaga saogalemu o le tert-butylphenol:

 

Tulaga lelei:

- Fa'aaliga: Tert-butylphenol ose ma'a tioata e leai se lanu pe samasama.

- Solubility: E maualalo le solubility i le vai ma sili atu le solubility i soluble organic.

- Aroma: E iai se manogi fa'apitoa o le phenol.

 

Fa'aaogā:

- Antioxidant: Tert-butylphenol e masani ona faʻaaogaina e fai ma antioxidant i mea faʻapipiʻi, paʻu, palasitika, ma isi mea e faʻalautele ai lona ola.

 

Metotia:

Tert-butylphenol e mafai ona saunia e ala i le nitrification o le p-toluene, ona faʻamaʻiina lea e maua ai le tert-butylphenol.

 

Fa'amatalaga Saogalemu:

- Tert-butylphenol e mu ma e ono tula'i mai se afi ma pa pe a fa'aalia i mu matala po'o le vevela maualuga.

- O le fa'aalia i le tert-butylphenol e ono i ai se aafiaga ita i le pa'u ma mata ma e tatau ona 'alofia.

- E mana'omia faiga puipuia lelei e pei o totigilima ma mata tioata pe a tagofia le tert-butylphenol.

- Tert-butylphenol e tatau ona tu'u ese mai mea e mu ma oxidants ma isi mea, ma ia aua ne'i o'o atu iai tamaiti. A lafoai, e tatau ona lafoai e tusa ai ma tulafono faatonutonu o le siosiomaga.
