    Fa'atatauga

    1. Mai le cyclopentanone ma le n-valeraldehyde e pei o mea mata, o le amyl cyclopentanone e fausia e ala i le condensation ma le faʻamaʻaina o aldol, ona faia lea o le hydrogenation catalytic filifili e maua ai le amyl cyclopentanone. Amyl cyclopentanone e malosi le manogi fuga ma fualaʻau ma le tofo jasmine, ma e mafai ona faʻaaogaina i aso taʻitasi vailaʻau tofo, ole fua e mafai ona itiiti ifo i le 20%. E leai ni tapula'a a le IFRA.

    2. E saunia le Hexylcyclopentanone mai le n-hexylaldehyde ma le cyclopentanone e ala ile condensation ona filifili lea ole hydrogenation. Hexylcyclopentanone o loʻo i ai se manogi malosi o le jasmine ma faʻatasi ma le manogi o fualaʻau, ma e mafai ona faʻaaogaina i le manogi ma isi vailaʻau faʻasolosolo i aso taʻitasi ma le fua i totonu ole 5%. E leai ni tapula'a a le IFRA.

    3. 1-pentene po'o le 1-heptene maua mai i le paraffin ta'e po'o le fa'amama le ava fa'atatau e pei o mea mata, i le i ai o le di-tert-butyl peroxyide e fai ma amataga, o le tali fa'aopoopo fa'atasi ma le cyclopentanone e fai ai le 2-amyl cyclopentanone (po'o 2-heptyl cyclopentanone), pe a uma ona faʻamaʻiina e avea ma delta-decalactone (poʻo delta-dodecalactone).

    4. O le auala fa'apipi'i fa'atasi ma le cyclopentanone e avea ma mea amata o lo'o i ai le tele o mea tau gaosiga fa'apisinisi. O le cyclopentanone e muamua fa'aputuina i le n-valeraldehyde, ma o le mea e maua mai ai Chemicalbook e fa'amama ma filifili fa'amamafa e fai ai le 2-amylcyclopentanone, ma mulimuli ane faia ai le delta-decalactone e ala i le fa'alauteleina o mama oxidative.

    5.delta-decanolactone e masani ona faʻaaogaina i meaʻai meaʻai, lea e talitonuina o loʻo i ai le tofo uiga o le kulimi masani. I luma o lenei, mo se taimi umi, na na o le faʻaaogaina o mea manogi monomer e pei o butanedion ma vanillin e avea ma mea autu mo le saunia o le kulimi. Ae ui i lea, e masani ona lagona e tagata o le tofo kulimi faʻafefiloi e matua laʻititi lava nai lo le mea masani i le tulaga o le tofo poʻo le tofo. E naʻo le faʻaaogaina o le delta-decalactone, e mafai ona i ai se tofo moni o le kulimi, aemaise lava le tuʻufaʻatasia o le delta-decalactone ma le delta-dodecalactone e avea ma mea manogi mataʻutia, o le tofo ma le aafiaga o le tofo kulimi saunia e sili atu.

    6.using cyclopentanone ma valeraldehyde e pei o mea mata, condensation e fai 2-(1-hydroxyl) amyl cyclopentanone, tali ma dimethyl malonate, ona mafai lea ona saunia hydrolysis i le 160 ~ 180 ℃, decarboxylated, esterification, dihydrojasmonate methyl ester. Methyl jasmonate dihydrojasmonate ose mea'ai le tumau fa'atagaina e GB2760-1996 i lo tatou atunu'u. O lona manogi e sili atu nai lo le natura methyl jasmonate, ma o ona meatotino e mautu.
