alpha-Ionone CAS Nr 127-41-3

alpha-Ionone (CAS Nr .: 127-41-3) cov ntaub ntawv

Violet ketone, tseem hu ua benzophenone, yog cov organic compound. Nov yog qee cov ntaub ntawv kev nyab xeeb txog ionone:

1. Toxicity: Violet ketone muaj qee yam toxicity rau tib neeg lub cev. Nws tuaj yeem ua rau muaj kev puas tsuaj rau lub hauv nruab nrab lub paj hlwb thiab lub siab, thiab tej zaum yuav muaj kev cuam tshuam tsis zoo rau lub cev xeeb tub thiab embryos.

2. Kev phom sij rau kev nqus pa: Kev nqus cov pa lossis plua plav ntawm ionone tuaj yeem ua rau cov tsos mob tsis xis nyob xws li kiv taub hau, tsaug zog, hnoos, thiab ua pa nyuaj. Kev raug mob mus ntev yuav ua rau muaj kev puas tsuaj rau lub hauv nruab nrab paj hlwb.

3. Kev phom sij: Violet ketone tuaj yeem nqus tau los ntawm daim tawv nqaij. Lub sij hawm ntev lossis kev sib cuag ntev yuav ua rau tawv nqaij thiab qhov muag khaus. Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes thiab tsom iav kev nyab xeeb yuav tsum hnav thaum tuav ionone.

4. Kev ntsuas kev tua hluav taws: Thaum muaj hluav taws xob los yog hluav taws, siv cov hmoov qhuav, ua npuas ncauj lossis carbon dioxide los tua hluav taws. Tsis txhob siv dej, vim violet ketone reacts nrog dej los tsim cov pa taws.

5. Kev pov tseg pov tseg: pov tseg cov khib nyiab violet ketone kom raug raws li cov cai hauv zos thiab cov cai. Tsis txhob tso nws mus rau hauv lub kav dej los yog cov khib nyiab.

6. Kev ceev faj khaws cia: Violet ketone yuav tsum muab cia rau hauv qhov chaw txias, qhuav, qhov cua zoo, kom deb ntawm qhov hluav taws kub thiab oxidants.

Cov ntaub ntawv no tsuas yog siv rau kev siv xwb. Yog xav tau kev siv ntxiv lossis kev ua haujlwm ntawm ionone, thov xa mus rau daim ntawv qhia txog kev nyab xeeb thiab sab laj nrog tus kws tshaj lij.

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.
