Folasaga

2-pentanone, e taʻua foʻi o le pentanone, o se faʻalapotopotoga faʻapitoa. O loʻo taua i lalo se faʻamatalaga i meatotino, faʻaoga, metotia sauniuni ma faʻamatalaga saogalemu o le 2-pentanone:

Tulaga lelei:

- Fa'aaliga: 2-pentanone ose vai e leai ni lanu ma se manogi fa'apitoa.

- Solubility: E mafai ona faʻamavaeina i le vai ma e faʻafefiloi foi ma le tele o vailaʻau faʻasolosolo.

- Fa'amumu: 2-pentanone ose vai e mu e mafai ona fa'atupu ai le afi i le tulaga o le mu matala po'o le maualuga o le vevela.

Fa'aaogā:

- Fa'aaogāga fa'apisinisi: 2-pentanone e fa'aaogaina e fai ma soli i le gaosiga o fa'alavalava, vaitusi, fa'apipi'i, ma isi mea, e pei o se fa'amama, fa'amama fa'amama, ma tali fa'avaitaimi.

Metotia:

- 2-pentanone e masani ona saunia e ala ile oxidizing pentanol. O se auala masani o le tali atu i le pentanol e se mea fa'ama'i fa'ama'i e pei o le okesene po'o le hydrogen peroxyide, ma fa'atelevave le tali mai se fa'alavelave e pei o le potassium chromate po'o le cerium oxide.

Fa'amatalaga Saogalemu:

- 2-pentanone e mu ma e tatau ona taofia mai le mu matala ma le vevela maualuga.

- Fai totigilima puipui, matatioata puipui, ma se talipupuni puipui e aloese ai mai le paʻi i mata, paʻu, ma asu.

- E tatau ona lafoa'i otaota e tusa ai ma tulafono ma tulafono fa'alotoifale, ma e le tatau ona lafoa'i i vai po'o le si'osi'omaga.

- Pe a teuina ma faʻaoga, faʻamolemole mulimulitaʻi lelei i le saogalemu o taualumaga ma taʻiala e faʻamautinoa ai lona faʻaoga tatau ma le teuina.
