1.Ho tloha cyclopentanone le n-valeraldehyde e le lisebelisoa tse tala, amyl cyclopentanone e thehoa ke aldol condensation le dehydration, 'me joale catalytic hydrogenation e khethiloeng e etsoa ho hlahisa amyl cyclopentanone. Amyl cyclopentanone e na le monko o matla oa lipalesa le litholoana le tatso ea jasmine, 'me e ka sebelisoa ka mokhoa oa letsatsi le letsatsi oa tatso ea lik'hemik'hale, litekanyetso li ka ba ka tlase ho 20%. IFRA ha e na lithibelo.
2. Hexylcyclopentanone e lokiselitsoe ho tloha n-hexylaldehyde le cyclopentanone ka condensation ebe e khetha hydrogenation. Hexylcyclopentanone e na le monko o matla oa jasmine 'me e tsamaisana le monko oa litholoana,' me e ka sebelisoa ho litlolo le litlolo tse ling tsa letsatsi le letsatsi tsa tatso ea lik'hemik'hale ka tekanyo ea 5%. IFRA ha e na lithibelo.
3. 1-pentene kapa 1-heptene e fumanoeng ka ho petsoha ha parafine kapa ho felloa ke metsi joala ka tsela e tšoanang e le lisebelisoa tse tala, ka pel'a di-tert-butyl peroxide e le mothehi, sehlopha sa mahala sa tlatsetso ka cyclopentanone ho theha 2-amyl cyclopentanone (kapa 2-heptyl cyclopentanone), ka mor'a hore oxidation e be delta-decalactone (kapa delta-dodecalactone).
4. Tsela ea ho kopanya le cyclopentanone e le thepa ea ho qala e na le boleng ba tlhahiso ea indasteri ka ho fetisisa. Cyclopentanone e qala ho koaheloa ka n-valeraldehyde, 'me Chemicalbook e hlahisoang e felloa ke metsi' me e khetha hydrogenated ho theha 2-amylcyclopentanone, 'me qetellong e thehe delta-decalactone ka ho eketsa lesale la oxidative.
5.delta-decanolactone e sebelisoa haholo-holo mefuteng ea tatso ea lijo, moo ho lumeloang hore e na le tatso ea tlhaho ea tranelate ea tlhaho. Pele ho sena, ka nako e telele, litlolo tse nkhang hamonate li ne li lekanyelitsoe feela ho sebelisoa ha linoko tsa monomer tse kang butanedione le vanillin e le thepa e ka sehloohong e tala bakeng sa ho lokisetsa tatso ea tranelate. Leha ho le joalo, batho ka kakaretso ba na le maikutlo a hore tatso ea tranelate e tsoakiloeng e tlase haholo ho feta sehlahisoa sa tlhaho ho latela tatso kapa tatso. Ke feela ka mor'a tšebeliso ea delta-decalactone, moo ho ka bang le tatso ea 'nete ea tranelate, haholo-holo motsoako oa delta-decalactone le delta-dodecalactone e le lisebelisoa tse ka sehloohong tsa monko o monate, tatso le phello ea tatso ea tranelate e lokiselitsoeng e molemo.
6.ho sebelisa cyclopentanone le valeraldehyde e le lisebelisoa tse tala, condensation ho theha 2- (1-hydroxyl) amyl cyclopentanone, karabelo le dimethyl malonate, ebe hydrolysis ka 160 ~ 180 ℃, decarboxylated, esterification, dihydrojasmonate methyl ester e ka lokisoa. Methyl jasmonate dihydrojasmonate ke tatso ea nakoana e jeoang e lumelletsoeng ke GB2760-1996 naheng ea rona. Monko oa eona o molemo ho feta methyl jasmonate ea tlhaho, 'me thepa ea eona e tsitsitse.
