Nhanganyaya kuDamascenone Isomers
Damascenone neβ-Damascenone ma isomers maviri akakosha emusanganiswa mumwe chete wemakemikari, ese ari maviri anoshandiswa zvakanyanya muindasitiri yekunhuhwirira nekunaka. Kunyange zvazvo vaine fomura imwe chete yemamorekuru (C₁₃H₁₈O), maumbirwo avo akasiyana emakemikari anokonzera kusiyana kukuru mumaitiro ekunhuhwirira uye mashandisirwo. Chinyorwa chino chinopa kuenzanisa kwakadzama kwemakemikari maviri aya anokosha ekunhuhwirira.
Kusiyana kweMagadzirirwo eKemikari
Musiyano mukuru pakati peDamascenone (kazhinji α-Damascenone) uye β-Damascenone uri mumaumbirwo avo emamorekuru:
·α-Damascenone: Zvinozivikanwa semakemikari se (E)-1-(2,6,6-trimethyl-1-cyclohexen-1-yl)-2-buten-1-one, ine chisungo chakapetwa kaviri chiri panzvimbo yeα (kabhoni yechipiri) yeringi yecyclohexene
·β-Damascenone: Muchimiro (E)-1-(2,6,6-trimethyl-1,3-cyclohexadien-1-yl)-2-buten-1-one, ine mabhondi maviri panzvimbo dzeβ (carbons yekutanga neyechitatu) dzecyclohexadiene ring
·Stereochemistry: Ose ari maviri aripo se (E) isomers (trans-configuration), izvo zvinokanganisa zvakanyanya hunhu hwavo hwekunhuhwirira

Kusiyana KwemaProfile Anonhuhwirira
Hunhu hweA-Damascenone hweManhuhwirira
·Chinyorwa Chekutanga: Muchero unotapira, wegirini, wemaruva
·Zvinyorwa Zvechipiri: Hunhu hwehuni nemuchero
·Kuonekwa Kwazvo: Zvakaoma zvikuru nechinhu chitsva, chakafanana nechirimwa
Hunhu hwemunhuhwi weβ-Damascenone
·Chinyorwa Chekutanga: Hunhu hwemaruva hwakasimba hwakaita seruva
· Zvinyorwa zvechipiri: Plum, grapefruit, raspberry, uye zvakafanana netii
·Kuonekwa Kwazvo: Kwakanyanya, kunodziya, nekupararira kuri nani uye kugara kwenguva refu
Kusiyana Kwekushandisa
Mashandisirwo Makuru eα-Damascenone
Zvinonhuhwirira zvepamusoro-soro: Zvinowedzera kuomarara uye kudzika kwezvinonhuhwirira
Kuravira kwechikafu: Kwakatenderwa sechinowedzera chikafu (GB 2760-96)
Kunhuhwirira kwefodya: Kunowedzera kupfava kwezvigadzirwa zvefodya
Mashandisirwo Akakosha eβ-Damascenone
Indasitiri yezvinonhuwira: Chinhu chikuru che rose accords muzvinonhuwira zvakanaka
Zvekuwedzera zvekudya: Zvinoshandiswa muzvinwiwa, muzvinwiwa zvakabikwa, uye muzvinwiwa
Kunhuhwirira kwefodya: Chinhu chikuru muzvinhu zvakawanda zvinonhuhwirira zvefodya
Zvigadzirwa zvetii: Hunhu hwemhando yepamusoro hwetii nhema dzine hwema hweuchi
Zviitiko zvechisikigo uye kukosha kwekutengeserana
Zvisikwa Zvechisikigo: Zvose izvi zvinowanikwa mumafuta erose, tii nhema, uye mafuta eraspberry
Kukosha Kwekutengeserana: β-Damascenone inotonga musika nekuda kwekunhuhwirira kwayo kwepamusoro
Kusiyana kweKukosheswa: β-isomer inowanzo kuwanikwa muhuwandu hwakawanda muzvigadzirwa zvechisikigo
Kugadzira uye Kugadzira
·Nzira dzekugadzira: Dzose dzinogona kugadzirwa kuburikidza neGrignard reaction yeβ-cyclocitral ichiteverwa neoxidation
··Maitiro Ekugadzira: Kugadzirwa kweα-Damascenone kwakaoma uye kunodhura
·Kuwanikwa Kwemusika: β-Damascenone inowanikwa zvakanyanya uye inodhura zvishoma
Mhedziso
Kunyange zvazvo α-Damascenone neβ-Damascenone zvakafanana mukugadzirwa kwemakemikari, nzvimbo yekubatana kwavo kaviri inoguma nemaitiro akasiyana ekunhuhwirira uye mashandisirwo. β-Damascenone, ine hunhu hwayo hwemaruva hwakaita seruva uye kupararira kwayo kwepamusoro, inonyanya kukosha mukutengeserana. Zvisinei, hunhu hwakaoma hwekunhuhwirira kweα-Damascenone hunochengetedza kukosha kwayo mune mamwe mashandisirwo epamusoro-soro. Kunzwisisa misiyano iyi kunobvumira vagadziri vezvinonhuhwirira nevanonaka kushandisa isomer yega yega zvinobudirira mukugadzirwa kwavo.
