I-Irisone(CAS#14901-07-6)

ethula
imvelo
I-Violet ketone, eyaziwa nangokuthi i-linaylketone, iyinhlanganisela ye-ketone yemvelo. Iyingxenye eyinhloko yephunga lezimbali ezi-violet.

I-Violet ketone iwuketshezi olunamafutha angenambala kuya kokuphuzi okuphaphathekile futhi oluguquguqukayo ezingeni lokushisa legumbi.

I-Violet ketone iyancibilika otshwaleni nasezincibilini ze-ether, futhi inyibilika kancane emanzini. Ukuminyana kwayo kuphansi uma kuqhathaniswa, nokuminyana kwayo okungu-0.87 g/cm ³. Iyazwela ekukhanyeni futhi ingakwazi ukumunca imisebe ye-ultraviolet.

I-Violet ketone ingafakwa i-oxidized ku-ketone alcohols noma ama-asidi ekuphenduleni kwamakhemikhali, futhi ingancishiswa ibe otshwala ngokusabela kokunciphisa i-hydrogenation. Ingabhekana ne-alkylation kanye nokusabela kwe-esterification ngezinhlanganisela eziningi.

Isicelo kanye nendlela yokuhlanganisa
I-Violet ketone (eyaziwa nangokuthi i-ketone ensomi) iyinhlanganisela ye-ketone enamakha. Inephunga elimnandi futhi ivame ukusetshenziswa embonini yamakha kanye neziqholo. Okulandelayo yisingeniso sokusetshenziswa nezindlela zokuhlanganiswa kwe-ionone:

Inhloso:
Amakha nezinongo: izici zephunga le-ionone, esetshenziswa kakhulu embonini yamakha nezinongo ukwenza imikhiqizo yephunga elibomvana.

Indlela yokuhlanganisa:
Ukuhlanganiswa kwe-ionone ngokuvamile kufinyelelwa ngezindlela ezimbili ezilandelayo:

I-Oxidation ye-Nucleobenzene: I-Nucleobenzene (indandatho ye-benzene ene-methyl substituent) ingaphansi kokusabela kwe-oxidation, njengokusebenzisa i-oxidizing acid noma i-acidic potassium permanganate solution, ukuze ikhiqize ionone.

Ukuhlangana kwe-Pyrylbenzaldehyde: I-Pyrylbenzaldehyde (njenge-benzaldehyde ene-pyridine ring substituents endaweni ye-para noma ye-meta) isabela nge-acetic anhydride nezinye izinto ezisabelayo ngaphansi kwezimo ze-alkali ukuze zenze i-ionone.
