1.Los ntawm cyclopentanone thiab n-valeraldehyde ua raw khoom, amyl cyclopentanone yog tsim los ntawm aldol condensation thiab lub cev qhuav dej, thiab ces xaiv catalytic hydrogenation yog ua los tsim amyl cyclopentanone.Amyl cyclopentanone muaj zog floral thiab fruity aroma thiab jasmine tsw, thiab yuav siv tau nyob rau hauv niaj hnub tshuaj tsw qab mis, qhov ntau npaum li cas yuav tsawg tshaj li 20%.IFRA tsis muaj kev txwv.
2. Hexylcyclopentanone yog npaj los ntawm n-hexylaldehyde thiab cyclopentanone los ntawm condensation thiab ces xaiv hydrogenation.Hexylcyclopentanone muaj ib tug muaj zog jasmine aroma thiab nrog txiv hmab txiv ntoo aroma, thiab yuav siv tau nyob rau hauv cov tshuaj tsw qab thiab lwm yam tshuaj tsw qab formulations txhua hnub nrog rau ntau npaum li cas nyob rau hauv 5%.IFRA tsis muaj kev txwv.
3. 1-pentene los yog 1-heptene tau los ntawm paraffin cracking los yog coj dej cawv dehydration raws li raw cov ntaub ntawv, nyob rau hauv lub xub ntiag ntawm di-tert-butyl peroxide raws li ib tug pib, cov dawb pab pawg neeg ntxiv cov tshuaj tiv thaiv nrog cyclopentanone los tsim 2-amyl cyclopentanone (los yog 2-heptyl cyclopentanone), tom qab oxidation los ua delta-decalactone (los yog delta-dodecalactone).
4. Txoj kev sib txuas nrog cyclopentanone raws li cov khoom pib muaj cov nqi tsim khoom lag luam tshaj plaws.Cyclopentanone yog thawj condensed nrog n-valeraldehyde, thiab cov ntaub ntawv uas tau tshwm sim yog lub cev qhuav dej thiab xaiv hydrogenated los ua 2-amylcyclopentanone, thiab thaum kawg tsim delta-decalactone los ntawm oxidative nplhaib o.
5.delta-decanolactone feem ntau yog siv hauv cov khoom noj qab zib formulations, qhov twg nws ntseeg tau tias muaj cov yam ntxwv tsw ntawm ntuj qab zib.Ua ntej no, ntev ntev, perfumers tsuas yog txwv rau kev siv cov txuj lom monomer xws li butanedione thiab vanillin ua cov khoom siv tseem ceeb rau kev npaj qab zib.Txawm li cas los xij, tib neeg feem ntau xav tias cov khoom qab zib sib xyaw yog qhov tsawg dua li cov khoom lag luam hauv cov ntsiab lus ntawm saj lossis tsw.Tsuas yog tom qab siv delta-decalactone, tuaj yeem muaj qhov tseeb tsw ntawm qab zib, tshwj xeeb tshaj yog kev sib xyaw ntawm delta-decalactone thiab delta-dodecalactone raws li cov khoom siv tseem ceeb aroma, qhov tsw thiab cov nyhuv ntawm cov qab zib npaj tau zoo dua.
6.siv cyclopentanone thiab valeraldehyde ua raw cov ntaub ntawv, condensation rau daim ntawv 2-(1-hydroxyl) amyl cyclopentanone, cov tshuaj tiv thaiv nrog dimethyl malonate, thiab ces hydrolysis ntawm 160 ~ 180 ℃, decarboxylated, esterification, dihydrojasmonate methyl ester tuaj yeem npaj.Methyl jasmonate dihydrojasmonate yog ib qho khoom noj khoom haus ib ntus tso cai los ntawm GB2760-1996 hauv peb lub tebchaws.Nws cov aroma zoo dua li ntuj methyl jasmonate, thiab nws cov khoom ruaj khov.
