1. Ho tloha ho cyclopentanone le n-valeraldehyde e le thepa e tala, amyl cyclopentanone e thehoa ka aldol condensation le dehydration, ebe ho etsoa hydrogenation e khethiloeng ea catalytic ho hlahisa amyl cyclopentanone. Amyl cyclopentanone e na le monko o matla oa lipalesa le litholoana le tatso ea jasmine, 'me e ka sebelisoa foromong ea tatso ea lik'hemik'hale ea letsatsi le letsatsi, tekanyo e ka ba ka tlase ho 20%. IFRA ha e na lithibelo.
2. Hexylcyclopentanone e lokisitsoe ho tsoa ho n-hexylaldehyde le cyclopentanone ka ho kolobisa ebe e kgetha hydrogenation. Hexylcyclopentanone e na le monko o matla oa jasmine 'me e tsamaea le monko oa litholoana, 'me e ka sebelisoa mefuteng e meng ea tatso ea lik'hemik'hale ea letsatsi le letsatsi ka tekanyo e ka hare ho 5%. IFRA ha e na lithibelo.
3. 1-pentene kapa 1-heptene e fumanoeng ka ho petsoha ha parafini kapa ho felloa ke metsi ha joala ho tsamaellanang le eona e le thepa e tala, ha ho na le di-tert-butyl peroxide e le sethatho, karabelo ea ho eketsa sehlopha ka bolokolohi le cyclopentanone ho theha 2-amyl cyclopentanone (kapa 2-heptyl cyclopentanone), kamora hore oxidation e fetohe delta-decalactone (kapa delta-dodecalactone).
4. Tsela ea ho kopanya le cyclopentanone e le thepa ea ho qala e na le boleng bo phahameng ka ho fetisisa ba tlhahiso ea indasteri. Cyclopentanone e qala ka ho kopanngoa le n-valeraldehyde, 'me Chemicalbook e hlahisoang e ntšoa metsi 'me e khetheloa hydrogen ho etsa 2-amylcyclopentanone, 'me qetellong ho theha delta-decalactone ka ho holisa lesale la oxidative.
5.delta-decanolactone e sebediswa haholo-holo mefuteng ya tatso ya dijo, moo ho dumelwang hore e na le tatso e ikgethang ya tranelate ya tlhaho. Pele ho sena, ka nako e telele, baetsi ba dinoko ba ne ba lekanyeditswe feela tshebedisong ya dinoko tsa monomer tse kang butanedione le vanillin e le thepa e ka sehloohong e tala bakeng sa ho lokisa tatso ya tranelate. Leha ho le jwalo, batho ka kakaretso ba ikutlwa hore tatso ya tranelate e kopantsweng e nyane haholo ho feta sehlahiswa sa tlhaho mabapi le tatso kapa tatso. Ke feela kamora tshebediso ya delta-decalactone, moo ho ka bang le tatso ya nnete ya tranelate, haholoholo motswako wa delta-decalactone le delta-dodecalactone e le monko o ka sehloohong wa thepa e tala, tatso le phello ya tatso ya tranelate e lokisitsweng e betere.
6. Ho sebelisoa cyclopentanone le valeraldehyde e le thepa e tala, ho kolobisa ho etsa 2-(1-hydroxyl) amyl cyclopentanone, karabelo le dimethyl malonate, ebe hydrolysis ho 160 ~ 180℃, decarboxylated, esterification, dihydrojasmonate methyl ester e ka lokisoa. Methyl jasmonate dihydrojasmonate ke tatso ea nakoana e jeoang e lumelloang ke GB2760-1996 naheng ea rona. Monko oa eona o betere ho feta methyl jasmonate ea tlhaho, 'me thepa ea eona e tsitsitse.
