nature
Violet ketone, inozivikanwawo se linaylketone, ndeye yakasikwa ketone komboni. Icho chikamu chikuru chekunhuhwirira kwemaruva e violet.
Violet ketone imvura isina ruvara kune yakachenuruka yero ine mafuta uye inoshanduka pakamuri tembiricha.
Violet ketone inonyungudika mudoro uye ether zvinonyungudutsa, uye inonyungudika zvishoma mumvura. Density yayo ishoma, ine density ye0.87 g/cm ³. Inonzwa kuchiedza uye inogona kutora ultraviolet rays.
Violet ketone inogona kuve oxidized kune ketone alcohols kana acids mumakemikari reactions, uye inogona kuderedzwa kusvika kudoro kuburikidza nehydrogenation reduction reactions. Inogona kuita alkylation uye esterification maitiro nemakomponi akawanda.
Kushandisa uye synthesis nzira
Violet ketone (inozivikanwawo seyepepuru ketone) inonhuhwirira ketone komboni. Iine kunhuhwirira kwakakosha uye inowanzoshandiswa muindasitiri yepefiyumu nepefiyumu. Iyi inotevera sumo yekushandiswa uye nzira dzekubatanidza ionone:
Chinangwa:
Perfume uye spice: kunhuhwirira maitiro eionone, ayo anoshandiswa zvakanyanya muindasitiri yepefume uye zvinonhuwira kugadzira zvigadzirwa zveviolet zvinonhuhwirira.
Synthesis nzira:
Iyo synthesis yeionone inowanikwa kuburikidza nenzira mbiri dzinotevera:
Oxidation yeNucleobenzene: Nucleobenzene (a benzene ring ine methyl substituent) inoiswa pasi pekuita oxidation, sekushandisa oxidizing acid kana acidic potassium permanganate solution, kugadzira ionone.
Kubatanidzwa kwePyrylbenzaldehyde: Pyrylbenzaldehyde (yakadai sebenzaldehyde nepyridine ring substituents mupara kana meta position) inobatwa neacetic anhydride uye zvimwe zvinogadzirisa pasi pemamiriro e-alkaline kuti iite ionone.
