qhia
xwm
Violet ketone, tseem hu ua linaylketone, yog lub ntuj ketone compound. Nws yog lub ntsiab tivthaiv ntawm aroma ntawm violet paj.
Violet ketone yog cov xim tsis muaj xim rau daj daj oily kua uas yog volatile ntawm chav tsev kub.
Violet ketone yog soluble hauv cawv thiab ether cov kuab tshuaj, thiab me ntsis soluble hauv dej. Nws qhov ceev yog qhov tsawg, nrog qhov ceev ntawm 0.87 g / cm³. Nws yog rhiab heev rau lub teeb thiab tuaj yeem nqus tau ultraviolet rays.
Violet ketone tuaj yeem oxidized rau ketone alcohols lossis acids hauv tshuaj lom neeg cov tshuaj tiv thaiv, thiab tuaj yeem txo cov cawv los ntawm kev txo qis hydrogenation. Nws tuaj yeem raug alkylation thiab esterification cov tshuaj tiv thaiv nrog ntau lub tebchaw.
Kev siv thiab kev sib xyaw ua ke
Violet ketone (tseem hu ua ntshav ketone) yog ib qho tshuaj tsw qab ketone. Nws muaj cov tshuaj tsw qab tshwj xeeb thiab feem ntau siv hauv kev lag luam naj hoom thiab naj hoom. Cov hauv qab no yog kev qhia txog kev siv thiab kev sib txuas ntawm ionone:
Lub hom phiaj:
Perfume thiab txuj lom: cov tshuaj tsw qab ntawm ionone, uas yog siv dav hauv kev lag luam naj hoom thiab txuj lom los tsim cov khoom siv tshuaj tsw qab violet.
Txoj kev Synthesis:
Lub synthesis ntawm ionone feem ntau ua tiav los ntawm ob txoj hauv qab no:
Oxidation ntawm Nucleobenzene: Nucleobenzene (lub nplhaib benzene nrog methyl hloov) yog raug rau cov tshuaj tiv thaiv oxidation, xws li siv cov oxidizing acid los yog acidic poov tshuaj permanganate tov, los tsim ionone.
Kev sib txuas ntawm Pyrylbenzaldehyde: Pyrylbenzaldehyde (xws li benzaldehyde nrog pyridine nplhaib hloov pauv hauv para lossis meta txoj hauj lwm) yog reacted nrog acetic anhydride thiab lwm yam reactants nyob rau hauv alkaline tej yam kev mob rau tsim ionone.
