alpha-Ionone (CAS#127-41-3) chidziwitso
Violet ketone, yomwe imadziwikanso kuti benzophenone, ndi organic pawiri. Nazi zina zokhudza chitetezo cha ionone:
1. Kawopsedwe: Violet ketone ili ndi kawopsedwe kena m'thupi la munthu. Zitha kuwononga dongosolo lapakati lamanjenje ndi chiwindi, ndipo zitha kukhala ndi zotsatirapo zoyipa pa ubereki ndi miluza.
2. Kuopsa kwa mpweya: Kupuma mpweya kapena fumbi la ionone kungayambitse zizindikiro zosasangalatsa monga chizungulire, kugona, kutsokomola, ndi kupuma movutikira. Kuwonekera kwa nthawi yayitali kungayambitse kuwonongeka kwa dongosolo la mitsempha.
3. Zowopsa: Violet ketone imatha kuyamwa kudzera pakhungu. Kulumikizana kwa nthawi yayitali kapena kwambiri kungayambitse khungu ndi maso. Zida zodzitetezera zoyenerera monga magolovesi ndi magalasi otetezera chitetezo ziyenera kuvalidwa pogwira ionone.
4. Njira zozimitsira moto: Ngati watuluka kapena moto, gwiritsani ntchito ufa wouma, thovu kapena mpweya woipa kuti muzimitse motowo. Pewani kugwiritsa ntchito madzi, chifukwa violet ketone imakhudzidwa ndi madzi kuti ipange mpweya woyaka.
5. Kutaya zinyalala: Tayani zinyalala za violet ketone moyenera motsatira malamulo ndi malamulo amderalo. Osatayira mu ngalande kapena nkhokwe ya zinyalala.
6. Njira zopewera kasungidwe: Violet ketone iyenera kusungidwa pamalo ozizira, owuma, opanda mpweya wabwino, kutali ndi magwero a moto ndi okosijeni.
Izi ndi zongonena zokha. Ngati kugwiritsidwa ntchito kwinanso kapena kukonza kwa ionone kumafunika, chonde onani tsamba loyenera lachitetezo ndikufunsani katswiri.
chilengedwe
Violet ketone, yomwe imadziwikanso kuti linaylketone, ndi gulu lachilengedwe la ketone. Ndilo gawo lalikulu la kununkhira kwa maluwa a violet.
Violet ketone ndi madzi amafuta amtundu wachikasu mpaka otumbululuka omwe amatha kusinthasintha kutentha.
Violet ketone imasungunuka mu mowa ndi zosungunulira za etha, ndipo zimasungunuka pang'ono m'madzi. Kachulukidwe ake ndi otsika, ndi kachulukidwe 0.87 g/cm ³. Imamva kuwala ndipo imatha kuyamwa cheza cha ultraviolet.
Violet ketone imatha kukhala oxidized kukhala ma ketone alcohols kapena acids mumayendedwe amankhwala, ndipo imatha kuchepetsedwa kukhala ma alcohols kudzera muzochita zochepetsera hydrogenation. Itha kukhala ndi alkylation ndi esterification reaction ndi mankhwala ambiri.
Ntchito ndi kaphatikizidwe njira
Violet ketone (yomwe imadziwikanso kuti purple ketone) ndi mankhwala onunkhira a ketone. Lili ndi fungo lapadera ndipo nthawi zambiri limagwiritsidwa ntchito popanga mafuta onunkhira komanso mafuta onunkhira. Zotsatirazi ndizomwe zimayambira pakugwiritsa ntchito ndi kaphatikizidwe ka ionone:
Cholinga:
Perfume ndi zokometsera: mawonekedwe a fungo a ionone, omwe amagwiritsidwa ntchito kwambiri m'makampani onunkhiritsa ndi zokometsera popanga zinthu zonunkhira za violet.
Njira yophatikizira:
Kaphatikizidwe ka ionone nthawi zambiri kamatheka kudzera m'njira ziwiri izi:
Oxidation wa Nucleobenzene: Nucleobenzene (mphete ya benzene yokhala ndi methyl substituent) imapangidwa ndi ma oxidation reaction, monga kugwiritsa ntchito oxidizing acid kapena acidic potassium permanganate solution, kuti apange ionone.
Kuphatikizika kwa Pyrylbenzaldehyde: Pyrylbenzaldehyde (monga benzaldehyde yokhala ndi pyridine ring substituents mu para kapena meta position) imayendetsedwa ndi acetic anhydride ndi zina zomwe zimakhudzidwa ndi zinthu zamchere kuti apange ionone.
