Kev tshawb nrhiav hauv vitro	Vanillylacetone zoo ib yam hauv cov qauv tshuaj rau lwm cov tshuaj tsw qab xws li vanillin thiab eugenol. Nws yog siv raws li ib tug flavoring additive nyob rau hauv sesame roj thiab fragrances los qhia ib tug txuj lom tsw. Ginger tsis muaj vanillylacetone; Ginger hloov mus rau gingerol los ntawm kev ua noj, uas yog qhov piv txwv tam sim no ntawm kev hloov pauv mus rau vanillylacetone los ntawm cov tshuaj tiv thaiv aldol condensation. Vanillylacetone tej zaum yuav yog cov khoom xyaw nquag ntawm cov qhiav kom siv tshuaj tiv thaiv kab mob.

Taw qhia

4-4-Hydroxy-3-methoxybutyl-2-one, tseem hu ua 4-hydroxy-3-methoxypentanone, yog cov organic compound. Cov hauv qab no yog kev qhia txog qee yam ntawm nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:

Zoo:

- Cov tsos mob: tsis muaj xim los yog lub teeb daj ua kua lossis khoom.

- Solubility: Soluble hauv cov kuab tshuaj organic xws li ethanol thiab dimethylformamide, insoluble hauv dej.

- Toxicity: Cov tshuaj muaj tshuaj lom thiab yuav tsum tau ntsuas kev nyab xeeb tsim nyog thaum nqus tau los yog sib cuag ntawm daim tawv nqaij.

Siv:

- Kev sim tshuaj Chemistry: Nws kuj tuaj yeem siv los ua cov tshuaj reagent rau qee qhov kev sim tshuaj.

Txoj kev:

Txoj kev npaj ntawm 4-4-hydroxy-3-methoxybutyl-2-one tuaj yeem ua tiav los ntawm cov organic synthesis raws li qhov tsim nyog. Tej zaum yuav muaj ntau txoj hauv kev los npaj nws, tab sis ntawm no yog ib txoj hauv kev tau:

Dissolve ib tug tsim nyog tus nqi ntawm pentanone nyob rau hauv ib tug organic hnyav.

Ntxiv cov tshuaj sodium hydroxide ntau dhau.

Ntawm qhov kub thiab txias tas li, methanol maj mam ntxiv dropwise rau hauv cov tshuaj tiv thaiv sib tov.

Nrog rau qhov sib ntxiv ntawm methanol, 4-4-hydroxy-3-methoxybutyl-2-one yog tsim nyob rau hauv cov tshuaj tiv thaiv sib tov.

Cov khoom lag luam tau ua tiav ntxiv thiab ua kom huv si kom tau txais qhov kawg compound.

Cov ntaub ntawv kev nyab xeeb:

- Cov tshuaj no yog tshuaj lom me ntsis thiab yuav tsum zam los ntawm kev nqus ncaj qha lossis sib cuag ntawm daim tawv nqaij.

- Kev ntsuas kev nyab xeeb tsim nyog yuav tsum tau ua thaum siv, xws li hnav cov tsom iav tshuaj, hnav cov hnab looj tes tshuaj thiab cov khaub ncaws tiv thaiv.

- Kev pov tseg pov tseg: Cov khib nyiab yog tov nrog cov kuab tshuaj uas tsim nyog thiab muab pov tseg los ntawm qhov chaw pov tseg uas tsim nyog raws li cov cai hauv zos.
