Folasaga
pent-4-ynoic acid, e ta'ua fo'i o le pent-4-ynoic acid, fua fa'ama'i C5H6O2. O loʻo taua i lalo se faʻamatalaga i le natura, faʻaogaina, faʻatulagaina ma faʻamatalaga saogalemu o le pent-4-ynoic acid:
natura:
- pent-4-ynoic acid o se vai e le lanu ma se manogi manogi.
-O lona tele mole mole feso'ota'iga o le 102.1g/mol.
Fa'aaogā:
- pent-4-ynoic acid o se mea taua tele i le fa'asologa o vaila'au ma fa'aaogaina e saunia ai isi mea fa'apipi'i.
-E mafai ona faʻaaogaina mo le carbonylation tali, condensation tali ma esterification tali i organic synthesis tali.
- pent-4-ynoic acid e mafai foi ona faʻaaogaina i le sauniuniga o vailaʻau, mea manogi ma vali.
Sauniuniga auala:
-O le sauniuniga o le pent-4-ynoic acid e mafai ona ausia e le 1-chloropentyne ma le acid hydrolysis. Muamua, o le 1-chloropentyne e faʻafefe i le vai e tuʻuina atu ai le aldehyde poʻo le ketone, ona liua lea o le aldehyde poʻo le ketone i le pent-4-ynoic acid e ala i le faʻamaʻiina.
Fa'amatalaga Saogalemu:
- pent-4-ynoic acid ose vailaʻau faʻafefe e mafai ona mafua ai le faʻaleagaina ma le mumu pe a faʻafesoʻotaʻi ma le paʻu ma mata.
- Fai totigilima puipui, matatioata, ma lavalava falesuesue pe a faʻaaogaina le pent-4-ynoic acid.
-I le tulaga o le paʻi i le paʻu poʻo mata, fufulu vave i le tele o vai ma saili togafitiga faafomaʻi.
- Aloese mai le faʻafesoʻotaʻi ma oxidants, malosi malosi ma faʻavae malosi i le taimi o le teuina ma faʻaoga e aloese ai mai faʻalavelave mataʻutia.
Faamolemole ia matau ae e te le'i fa'aogaina so'o se vaila'au, e tatau ona e faitau ma le fa'aeteete le pepa o fa'amaumauga mo le saogalemu (MSDS) o le vaila'au ma mulimulita'i i auala sa'o fa'agaioiga ma fa'agaioiga saogalemu.
