1. Los ntawm cyclopentanone thiab n-valeraldedehyde ua cov khoom siv raw, amyl cyclopentanone yog tsim los ntawm aldol condensation thiab dehydration, thiab tom qab ntawd xaiv catalytic hydrogenation yog ua los tsim amyl cyclopentanone. Amyl cyclopentanone muaj zog paj thiab txiv hmab txiv ntoo aroma thiab jasmine tsw, thiab tuaj yeem siv rau hauv cov tshuaj tsw qab txhua hnub, qhov koob tshuaj tuaj yeem tsawg dua 20%. IFRA tsis muaj kev txwv.
2. Hexylcyclopentanone yog npaj los ntawm n-hexylaldehyde thiab cyclopentanone los ntawm kev sib xyaw ua ke thiab tom qab ntawd xaiv hydrogenation. Hexylcyclopentanone muaj lub ntxhiab tsw qab ntawm jasmine thiab nrog rau lub ntxhiab txiv hmab txiv ntoo, thiab tuaj yeem siv rau hauv tshuaj tsw qab thiab lwm yam tshuaj tsw qab txhua hnub nrog cov koob tshuaj hauv 5%. IFRA tsis muaj kev txwv.
3. 1-pentene lossis 1-heptene tau los ntawm paraffin cracking lossis cov cawv dehydration ua cov khoom siv raw, nyob rau hauv qhov muaj di-tert-butyl peroxide ua tus pib, cov pab pawg dawb ntxiv cov tshuaj tiv thaiv nrog cyclopentanone los tsim 2-amyl cyclopentanone (lossis 2-heptyl cyclopentanone), tom qab oxidation los ua delta-decalactone (lossis delta-dodecalactone).
4. Txoj kev tsim cov tshuaj cyclopentanone ua cov khoom pib muaj txiaj ntsig zoo tshaj plaws hauv kev lag luam. Cyclopentanone thawj zaug raug condensed nrog n-valeraldedehyde, thiab cov tshuaj Chemicalbook tau qhuav thiab xaiv hydrogenated los ua 2-amylcyclopentanone, thiab thaum kawg los tsim delta-decalactone los ntawm oxidative ring enlargement.
5.delta-decanolactone feem ntau yog siv rau hauv cov khoom noj khoom haus tsw qab, qhov twg nws ntseeg tias muaj cov yam ntxwv tsw ntawm cov tshuaj pleev ib ce ntuj. Ua ntej qhov no, tau ntev, cov kws ua tshuaj tsw qab tsuas yog txwv rau kev siv cov txuj lom monomer xws li butanedione thiab vanillin ua cov khoom siv tseem ceeb rau kev npaj cov tsw qab qab zib. Txawm li cas los xij, cov neeg feem ntau xav tias cov tsw qab qab zib sib xyaw yog tsawg dua li cov khoom ntuj hauv cov nqe lus ntawm saj lossis tsw. Tsuas yog tom qab siv delta-decalactone, tuaj yeem muaj cov tsw qab qab zib tiag tiag, tshwj xeeb tshaj yog kev sib xyaw ua ke ntawm delta-decalactone thiab delta-dodecalactone ua cov khoom siv tsw qab tseem ceeb, cov tsw thiab cov nyhuv ntawm cov tsw qab qab zib npaj tau zoo dua.
6. Siv cyclopentanone thiab valeraldede ua cov khoom siv raw, condensation los ua 2-(1-hydroxyl) amyl cyclopentanone, tshuaj tiv thaiv nrog dimethyl malonate, thiab tom qab ntawd hydrolysis ntawm 160 ~ 180 ℃, decarboxylated, esterification, dihydrojasmonate methyl ester tuaj yeem npaj tau. Methyl jasmonate dihydrojasmonate yog ib qho tsw qab ib ntus uas tau tso cai los ntawm GB2760-1996 hauv peb lub tebchaws. Nws cov aroma zoo dua li cov methyl jasmonate ntuj, thiab nws cov khoom ruaj khov.
