kev taw qhia
Phenylacetaldehyde, tseem hu ua benzaldehyde, yog ib qho organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm phenylacetaldehyde:

Zoo:
- Cov tsos mob: Phenylacetaldehyde yog cov kua tsis muaj xim lossis daj.
- Solubility: Nws tuaj yeem yaj hauv ntau cov kuab tshuaj organic, xws li ethanol, ether, thiab lwm yam.
- Tsis hnov ​​tsw: Phenylacetaldehyde muaj ib tug muaj zog aromatic tsw.

Siv:

Txoj kev:
Muaj ntau txoj hauv kev rau kev npaj phenylactaldehyde, suav nrog ob qho hauv qab no:
Ethylene thiab styrene yog oxidized nyob rau hauv catalysis ntawm ib tug oxidant kom tau phenylacetaldehyde.
Phenyethane yog oxidized los ntawm oxidizer kom tau phenylacetaldehyde.

Cov ntaub ntawv kev nyab xeeb:
- Thaum muaj kev sib cuag nrog phenylacetaldehyde, ntxuav tam sim nrog xab npum thiab dej thiab tsis txhob kov ncaj qha rau ntawm daim tawv nqaij thiab qhov muag.
- Kev saib xyuas yuav tsum tau ua kom tsis txhob nqus cov phenylacetaldehyde thaum siv nws cov vapors, uas ua rau khaus rau ntawm lub ntsws.
- Thaum siv lossis khaws cia phenylacetaldehyde, kom deb ntawm qhov hluav taws kub thiab kub kom tsis txhob muaj hluav taws kub lossis tawg.
- Thaum khaws cia thiab tuav phenylacetaldehyde, siv cov kev tiv thaiv tsim nyog, xws li hnav hnab looj tes, tsom iav, thiab khaub ncaws ua haujlwm.
