Folasaga

O le cyclopentanone, e taʻua foi o le pentanone, o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se fa'amatalaga i meatotino, fa'aoga, tapenaga ma fa'amatalaga saogalemu ole cyclopentanone:

 

Tulaga lelei:

2. Fa'aaliga: vai manino le lanu

3. Tofo: E manogi leaga

5. Malosi: 0.81 g/mL

6. Solubility: Solu i le vai, ava malosi ma solu masani masani

 

Fa'aaogā:

1. Fa'aaogāga fa'apisinisi: O le Cyclopentanone e masani ona fa'aaogaina e avea o se solvent ma e mafai ona fa'aaogaina i le gaosiga o fa'alavalava, resini, fa'apipi'i, ma isi.

2. Reagent i vailaʻau faʻamaʻi: Cyclopentanone e mafai ona faʻaaogaina e fai ma mea faʻapipiʻi mo le tele o gaioiga faʻasolosolo faʻasolosolo, e pei o faʻamaʻi faʻamaʻi, faʻaitiitiga faʻaitiitiga, ma le faʻapipiʻiina o mea faʻapipiʻi carbonyl.

 

Metotia:

O le cyclopentanone e masani ona saunia e ala i le vaeluaina o le butyl acetate:

CH3COC4H9 → CH3COCH2CH2CH2CH3 + C2H5OH

 

Fa'amatalaga Saogalemu:

1. Cyclopentanone e fa'aitaitagofie ma e tatau ona 'alofia pe a fa'afeso'ota'i ma le pa'u ma mata, ma 'alofia le manavaina o ana ausa.

2. E tatau ona faia ni faiga sa'o ile ea ile taimi ole fa'agaioiga ma fa'aaoga mea e puipui ai le tagata lava ia e pei o totigilima ma matatioata saogalemu.

3. O le Cyclopentanone o se vai e mu ma e tatau ona teu ese mai afi matala ma puna maualuga o le vevela i se nofoaga malulu ma lelei le savili.

4. Afai na e inuina fa'afuase'i pe manavaina se aofaiga tele o le cyclopentanone, e tatau ona e vave saili togafitiga faafoma'i. Afai e te maua le mumu, mageso, poʻo le mu i ou mata poʻo le paʻu, fufulu i le tele o vai ma faʻafesoʻotaʻi se fomaʻi.
