Taw qhia
Phenylpropionaldehyde, tseem hu ua benzylforme. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm phenylpropionaldehyde:
1. Xwm:
- Cov tsos mob: Phenylpropional yog cov kua tsis muaj xim uas qee zaum tuaj yeem daj.
- Ntsim: nrog ib qho tshwj xeeb aromatic aroma.
- Ceev: kuj siab.
- Solubility: Soluble nyob rau hauv ntau cov organic solvents, xws li cawv thiab ethers.
2. Kev siv:
- Chemical synthesis: Phenylpropionaldehyde yog ib qho tseem ceeb raw cov ntaub ntawv rau ntau cov organic synthesis, uas yuav siv tau los npaj ntau yam organic tebchaw.
3. Txoj kev:
- acetic anhydride txoj kev: Phenylpropanol yog reacted nrog acetic anhydride nyob rau hauv acid-catalyzed tej yam kev mob los tsim phenylpropylacetic anhydride, uas yog ces devinegared rau benzyl acetic acid, thiab thaum kawg hloov mus rau phenylpropional los ntawm oxidation.
- Cov txheej txheem teb: Phenylpropyl bromide yog reacted nrog sib tov ntawm sodium cyanide thiab sodium hydroxide los tsim phenylpropionazone, uas yog ces hydrolyzed los ntawm cua sov kom tau benzylamine, thiab thaum kawg oxidized rau phenylpropionaldehyde.
4. Cov ntaub ntawv kev nyab xeeb:
- Phenylpropional yog khaus thiab corrosive, kev sib cuag nrog cov tawv nqaij thiab qhov muag yuav tsum zam, thiab cov hnab looj tes tiv thaiv thiab tsom iav yuav tsum hnav yog tias tsim nyog.
- Thaum siv thiab khaws cia, yuav tsum tau them nyiaj rau qhov kev pheej hmoo ntawm kev tiv thaiv hluav taws thiab kev tsim kho zoo li qub.
- Phenylpropionaldehyde tuaj yeem ua rau muaj kev phom sij rau ib puag ncig, thiab kev tiv thaiv ib puag ncig tsim nyog yuav tsum tau coj los daws nws thaum nws xau.
