i-alpha-Ionone(I-CAS#127-41-3) ulwazi
I-Violet ketone, eyaziwa nangokuthi i-benzophenone, iyinhlanganisela yezinto eziphilayo. Nalu ulwazi lokuphepha mayelana ne-ionone:
1. Ubuthi: I-Violet ketone inobuthi obuthile emzimbeni womuntu. Kungase kubangele ukulimala ohlelweni lwezinzwa olumaphakathi nesibindi, futhi kungase kube nemiphumela emibi ohlelweni lokuzala kanye nemibungu.
2. Ingozi yokuhogela: Ukuhogela umhwamuko noma uthuli lwe-ionone kungase kubangele izimpawu zokungaphatheki kahle njengesiyezi, ukozela, ukukhwehlela, nokuphefumula kanzima. Ukuchayeka isikhathi eside kungase kubangele ukulimala ohlelweni lwezinzwa olumaphakathi.
3. Ingozi yokuxhumana: I-Violet ketone ingamuncwa ngesikhumba. Ukuxhumana isikhathi eside noma okujulile kungase kubangele ukucasuka kwesikhumba namehlo. Izimpahla zokuzivikela ezifanele ezifana namagilavu nezibuko zokuphepha kufanele zigqokwe lapho uphatha i-ionone.
4. Izinyathelo zokucima umlilo: Uma kuvuza noma umlilo, sebenzisa impushana eyomile, igwebu noma isikhutha ukuze ucime umlilo. Gwema ukusebenzisa amanzi, njengoba i-violet ketone isabela emanzini ukukhiqiza amagesi avuthayo.
5. Ukulahlwa kwemfucuza: Lahla imfucuza ye-violet ketone ngendlela efanele ngokuhambisana nemithetho nemithetho yendawo. Ungawukhiphi epayipini lendle noma emgqonyeni kadoti.
6. Izinyathelo zokuvikela isitoreji: I-Violet ketone kufanele igcinwe endaweni epholile, eyomile, nendawo engenisa umoya, kude nemithombo yomlilo nama-oxidants.
Le mininingwane ingeyereferensi kuphela. Uma kudingeka ukusetshenziswa okwengeziwe noma ukucutshungulwa kwe-ionone, sicela ubheke ishidi ledatha yokuphepha elifanele futhi uxhumane nochwepheshe.
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.
