Intangiriro kuri Damascenone Isomers
Damascenone na β-Damascenone ni isomeri ebyiri z'ingenzi z'ikinyabutabire kimwe, zombi zikoreshwa cyane mu nganda zitanga impumuro nziza n'uburyohe. Nubwo zisangiye formula imwe ya molekile (C₁₃H₁₈O), imiterere yazo itandukanye ya shimi ituma habaho itandukaniro rikomeye mu miterere y'impumuro nziza n'ikoreshwa ryayo. Iyi nkuru itanga igereranya rirambuye ry'izi mpumuro ebyiri z'agaciro.
Itandukaniro mu miterere y'ibinyabutabire
Itandukaniro ry'ibanze hagati ya Damascenone (ubusanzwe α-Damascenone) na β-Damascenone riri mu miterere ya molekile zabo:
·α-Damascenone: Izwi nka (E)-1-(2,6,6-trimethyl-1-cyclohexen-1-yl)-2-buten-1-one, hamwe n'umugozi ubiri uri ku mwanya wa α (karuboni ya kabiri) w'impeta ya cyclohexene
·β-Damascenone: Mu miterere (E)-1-(2,6,6-trimethyl-1,3-cyclohexadien-1-yl)-2-buten-1-one, ifite imigozi ibiri ku myanya ya β (karubone ya mbere n'iya gatatu) y'impeta ya cyclohexadiene
·Stereochemistry: Zombi zibaho nka (E) isomers (trans-configuration), ibyo bigira ingaruka ku buryo bugaragara ku miterere yazo y'impumuro

Itandukaniro ry'imiterere y'impumuro nziza
Imiterere y'impumuro ya α-Damascenone
·Icyitonderwa cy'ibanze: Imbuto nziza, icyatsi kibisi, indabyo
·Ibisobanuro by'inyongera: Uduce tw'ibiti n'imbuto z'umuhondo
· Ishusho rusange: Igoye cyane hamwe n'ubwiza bushya, busa n'ubw'ibimera
Imiterere y'impumuro ya β-Damascenone
·Icyitonderwa cy'ibanze: Indabyo zikomeye nk'iz'iroza
·Ibisobanuro bya kabiri: Imbuto za plum, grapefruit, raspberry, n'ibisa n'icyayi
· Ishusho rusange: Ikomeye cyane, ishyushye, ikwirakwira neza kandi iramba
Itandukaniro mu mikoreshereze
Porogaramu z'ingenzi za α-Damascenone
Impumuro nziza cyane: Yongera ubwinshi n'uburemere mu miterere y'impumuro nziza
Uburyohe bw'ibiribwa: Byemejwe nk'inyongeramusaruro ku biryo (GB 2760-96)
Uburyohe bw'itabi: Bwongera uburyohe bw'itabi
Porogaramu z'ingenzi za β-Damascenone
Inganda zikora impumuro nziza: Igice cy'ingenzi cy'impumuro nziza z'indabyo z'indabyo z'indabyo
Inyongeramusaruro ku biribwa: Ikoreshwa mu nganda zitunganya amacandwe, ibiryo bitetse, n'ibinyobwa
Uburyohe bw'itabi: Ikintu cy'ingenzi mu buryohe bwinshi bw'itabi
Ibikomoka ku cyayi: Impumuro yihariye mu cyayi cy'umukara gifite impumuro y'ubuki
Ibintu bisanzwe n'akamaro k'ubucuruzi
Inkomoko karemano: Byombi biboneka mu buryo busanzwe mu mavuta y'iroza, icyayi cy'umukara, n'amavuta ya raspberry
Akamaro k'ubucuruzi: β-Damascenone yiganje ku isoko kubera impumuro nziza cyane
Itandukaniro ry'ubwinshi: β-isomer ikunze kugaragara mu bwinshi bw'ibicuruzwa karemano
Gukora no Gutunganya
·Uburyo bwo gukora: Byombi bishobora gukorwa binyuze mu buryo bwa Grignard bwa β-cyclocitral hanyuma bigakurikirwa na oxidation
··Inzira yo gukora: Ikorwa rya α-Damascenone riragoye cyane kandi rirahenze
·Kuboneka kw'isoko: β-Damascenone iraboneka cyane kandi ihendutse cyane
Umwanzuro
Nubwo α-Damascenone na β-Damascenone bisangiye imiterere isa ya shimi, aho bihurira kabiri bitanga imiterere n'ikoreshwa ry'impumuro zitandukanye. β-Damascenone, ifite imiterere y'indabyo isa n'iroza kandi ikwirakwira cyane, ifite akamaro kanini mu bucuruzi. Ariko, impumuro igoye ya α-Damascenone igumana agaciro kayo mu buryo bumwe na bumwe bwo ku rwego rwo hejuru. Gusobanukirwa iri tandukaniro bituma abakora impumuro nziza n'abakora uburyohe bakoresha neza buri isomer mu buryo bwabo.
