1.Kuvamo cyclopentanone na n-valeraldehyde nkibikoresho fatizo, amyl cyclopentanone ikorwa na aldol condensation hamwe na dehidrasi, hanyuma hakorwa hydrogenation ya catalitiki ya catalitiki kugirango ikore amyl cyclopentanone.Amyl cyclopentanone ifite indabyo nimbuto nziza nimpumuro nziza ya jasine, kandi irashobora gukoreshwa mumata ya chimique ya buri munsi, dosiye irashobora kuba munsi ya 20%.IFRA nta mbogamizi ifite.
2. Hexylcyclopentanone itegurwa kuva n-hexylaldehyde na cyclopentanone hamwe na kondegene hanyuma ikavamo hydrogenation.Hexylcyclopentanone ifite impumuro nziza ya jasimine kandi iherekejwe nimpumuro nziza yimbuto, kandi irashobora gukoreshwa muri parufe nubundi buryohe bwa chimique bwa buri munsi hamwe na dosiye iri muri 5%.IFRA nta mbogamizi ifite.
3 2-heptyl cyclopentanone), nyuma ya okiside kugirango ibe delta-decalactone (cyangwa delta-dodecalactone).
4. Inzira ya synthesis hamwe na cyclopentanone nkibikoresho byo gutangira bifite agaciro keza cyane munganda.Cyclopentanone yabanje guhuzwa na n-valeraldehyde, hanyuma ibisubizo bivamo Chemical bigahumeka kandi bigahitamo hydrogène kugirango bibe 2-amylcyclopentanone, hanyuma amaherezo bibe delta-decalactone no kwagura impeta ya okiside.
5.delta-decanolactone ikoreshwa cyane cyane muburyohe bwibiryo, aho bikekwa ko bifite uburyohe bwa cream naturel.Mbere yibi, igihe kinini, parufe yagarukiraga gusa ku gukoresha ibirungo bya monomer nka butanedione na vanillin nkibikoresho nyamukuru byo gutegura uburyohe bwa cream.Nyamara, abantu muri rusange bumva ko uburyohe bwa cream ivanze ari munsi yibicuruzwa bisanzwe muburyohe cyangwa uburyohe.Gusa nyuma yo gukoresha delta-decalactone, hashobora kubaho uburyohe bwukuri bwa cream, cyane cyane guhuza delta-decalactone na delta-dodecalactone nkibikoresho nyamukuru byimpumuro nziza, uburyohe ningaruka za cream flavour yateguwe nibyiza.
6.koresha cyclopentanone na valeraldehyde nkibikoresho fatizo, kondegene kugirango ibe 2- (1-hydroxyl) amyl cyclopentanone, reaction na dimethyl malonate, hanyuma hydrolysis kuri 160 ~ 180 ℃, decarboxylated, esterification, dihydrojasmonate methyl ester irashobora gutegurwa.Methyl jasmonate dihydrojasmonate ni uburyohe bwo kuribwa byigihe gito byemewe na GB2760-1996 mugihugu cyacu.Impumuro yayo iruta methyl jasmonate karemano, kandi imiterere yayo irahagaze.
200kg / ingoma 20'FCL irashobora gufata toni 16
