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.
