Cyclopentanone CAS 120-92-3
Cyclopentanone imadziwikanso kuti Adipic Ketono.Mafuta amadzimadzi osawoneka bwino.Kukhala ndi etheric yodziwika bwino, fungo la tinthu tating'onoting'ono.

1.Kuchokera ku cyclopentanone ndi n-valeraldehyde monga zopangira, amyl cyclopentanone imapangidwa ndi aldol condensation ndi kutaya madzi m'thupi, ndiyeno kusankha catalytic hydrogenation kumapangidwa kuti apange amyl cyclopentanone.Amyl cyclopentanone ali ndi fungo lamphamvu lamaluwa ndi zipatso komanso kukoma kwa jasmine, ndipo angagwiritsidwe ntchito tsiku ndi tsiku kununkhira kwamankhwala, mlingo ukhoza kukhala wosakwana 20%.IFRA ilibe zoletsa.
2. Hexylcyclopentanone imakonzedwa kuchokera ku n-hexylaldehyde ndi cyclopentanone ndi condensation ndiyeno kusankha hydrogenation.Hexylcyclopentanone ali ndi fungo lamphamvu la jasmine ndi fungo la zipatso, ndipo angagwiritsidwe ntchito mu zonunkhira ndi zina zatsiku ndi tsiku kununkhira kwa mankhwala ndi mlingo mkati mwa 5%.IFRA ilibe zoletsa.
3. 1-pentene kapena 1-heptene yomwe imapezedwa ndi parafini yosweka kapena kutaya madzi m'thupi monga zopangira, pamaso pa di-tert-butyl peroxide monga woyambitsa, gulu laulere lowonjezera zomwe zimachitika ndi cyclopentanone kupanga 2-amyl cyclopentanone (kapena 2-heptyl cyclopentanone), pambuyo pa okosijeni kukhala delta-decalactone (kapena delta-dodecalactone).
4. Njira yophatikizira ndi cyclopentanone monga zoyambira zili ndi mtengo wopangira mafakitale.Cyclopentanone imayamba kusungunuka ndi n-valeraldehyde, ndipo zotsatira zake Chemicalbook imachotsedwa madzi ndi kusankha hydrogenated kupanga 2-amylcyclopentanone, ndipo potsiriza kupanga delta-decalactone ndi oxidative ring kukulitsa.
5.delta-decanolactone imagwiritsidwa ntchito makamaka popanga zakudya zokometsera, pomwe amakhulupirira kuti ili ndi kukoma kwamafuta achilengedwe.Izi zisanachitike, kwa nthawi yayitali, onunkhira amangogwiritsa ntchito zonunkhira za monomer monga butanedione ndi vanillin monga zida zazikulu zopangira zokometsera zonona.Komabe, anthu nthawi zambiri amaona kuti kukoma kwa kirimu wosakaniza ndi kochepa kwambiri kusiyana ndi mankhwala achilengedwe malinga ndi kukoma kapena kukoma.Pokhapokha mutagwiritsa ntchito delta-decalactone, pangakhale kukoma kwenikweni kwa kirimu, makamaka kuphatikiza kwa delta-decalactone ndi delta-dodecalactone monga fungo lalikulu la zipangizo zopangira, kununkhira ndi zotsatira za zokometsera zokometsera zokonzedwa bwino.
6.kugwiritsa ntchito cyclopentanone ndi valeraldehyde monga zopangira, condensation kupanga 2-(1-hydroxyl) amyl cyclopentanone, zochita ndi dimethyl malonate, ndiyeno hydrolysis pa 160 ~ 180 ℃, decarboxylated, esterification, dihydrojasmonate methyl ester akhoza kukonzekera.Methyl jasmonate dihydrojasmonate ndi kukoma kwakanthawi kodyedwa kololedwa ndi GB2760-1996 m'dziko lathu.Kununkhira kwake kuli bwino kuposa methyl jasmonate yachilengedwe, ndipo katundu wake ndi wokhazikika.
