Folasaga

O le Isoamyl alcohol, e ta'ua fo'i o le isobutanol, o lo'o iai le fua fa'atatau C5H12O. O lo'o ta'ua i lalo se folasaga i lona natura, fa'aoga, auala sauniuni ma fa'amatalaga saogalemu:

 

Tulaga lelei:

1. Isoamyl alcohol o se vai e leai ni lanu ma se manogi uaina faapitoa.

2. O lo'o i ai se mea fa'apuna a'e o le 131-132 °C ma le fa'amauina o le 0.809g/mLat 25 °C (malamalama).

3. Isoamil alcohol e solu i le vai ma le tele o so'o so'o.

 

Fa'aaogā:

1. O le Isoamyl alcohol e masani ona faʻaaogaina e avea o se solvent ma e iai le tele o faʻaoga i paʻu, vaitusi, faʻapipiʻi ma mea faʻamamaina.

2. E mafai fo'i ona fa'aoga le Isoamil alcohol e fa'afefiloi ai isi mea fa'afefiloi e pei ole eter, esters, ma aldehydes ma ketones.

 

Metotia:

1. O se metotia masani o sauniuniga o le isoamyl alcohol e maua mai i le fa'afefe o le ava malosi o le ethanol ma le isobutylene.

2. O le isi auala sauniuni e maua i le hydrogenation o le isobutylene.

 

Fa'amatalaga Saogalemu:

1. O le Isoamyl alcohol ose vai e mu e mafai ona tupu ai se afi pe a fa'aalia i se mea e mu ai.

2. Pe a faʻaaoga le isoamyl alcohol, e tatau ona aloese mai le manava, faʻafesoʻotaʻi ma le paʻu poʻo le ingestion i totonu o le tino e puipuia ai le faʻaleagaina o le soifua maloloina.

3. E tatau ona faia faiga lelei ea lelei pe a fa'aogaina le isoamyl alcohol e fa'amautinoa ai le fa'aogaina o le ea i totonu.

4. I le tulaga o le leakage, o le isoamyl alcohol e tatau ona vavaeeseina vave, ma le leakage e tatau ona lafoai lelei ina ia aloese mai le tali atu i isi mea.
