Maple Furanone（CAS#698-10-2）

Folasaga

(5h) o le furanone ose fa'aputuga fa'aola ma le fua fa'ama'i C8H12O3 ma le mamafa mole e 156.18g/mol. O se vai e leai se lanu e o'o i le samasama samasama ma se suka-suamalie fa'apitoa. O lo'o taua i lalo se fa'amatalaga o lona natura, fa'aoga, sauniuniga ma fa'amatalaga saogalemu:

natura:

- Fa'aaliga: E leai se lanu i le vai samasama mumu

-Meli liusuavai:-7 ℃

-Puna: 171-173 ℃

-Tomia: tusa. 1.079g/cm³

-Solubility: E mafai ona solo i vai, ethanol ma Eter solvents

- Fa'amautu: mautu i le vevela o le potu

Fa'aaogā:

-Fa'aopoopo mea'ai: Ona o lona suamalie fa'apitoa, e fa'aaogaina e fai ma mea'ai mea'ai, aemaise lava i lole, siamu ma mea'ai suamalie.

- Mea manogi: E mafai ona faʻaaogaina e fai ma faʻamalo e tuʻuina atu ai meaʻai se tofo tulaga ese.

- alamanuia manogi: o se tasi o vaega o le manogi manogi.

Metotia:

(5h) furanone e mafai ona saunia i laasaga nei:

1. Faatasi ai ma le 3-methyl -2-pentanone e avea ma mea amata, 3-hydroxy -4-methyl -2-pentanone na maua mai i le keto-alcohol reaction.

O le 2.3-hydroxy -4-methyl -2-pentanone e tali atu i se vaila'au eterifying (e pei o le diethyl ether) e gaosia ai se oloa etherification.

3. O le etherification oloa e fa'atatau i le acid catalysis ma deoxidation tali e maua ai furanone (5h).

Fa'amatalaga Saogalemu:

-(5h) furanone e manatu e saogalemu mo le fa'aoga lautele, ae e ono fa'aita i le pa'u ma mata pe a maualuga.

-O le fa'aoga e tatau ona fa'alogo lelei i le puipuiga, aloese mai le fa'afeso'ota'i ma le pa'u ma mata, ma fa'atumauina se siosiomaga faigaluega lelei.

-Mulimuli i faiga talafeagai mo le saogalemu pe a faʻaaogaina, ma teu i se nofoaga matutu, malulu, ese mai afi ma faʻamaʻi faʻamaʻi.
