Taw qhia

Zoo:

- Cov tsos mob: Benzoaldehyde yog cov kua tsis muaj xim, tab sis cov qauv coj mus muag yog daj.

- Smell: muaj ib qho aromatic aroma.

 

Txoj kev:

Benzoaldehyde tuaj yeem npaj los ntawm oxidation ntawm hydrocarbons. Feem ntau siv cov txheej txheem npaj muaj xws li hauv qab no:

- Oxidation los ntawm phenol: Nyob rau hauv lub xub ntiag ntawm ib tug catalyst, phenol yog oxidized los ntawm oxygen nyob rau hauv cov huab cua los tsim benzaldehyde.

- Catalytic oxidation los ntawm ethylene: Nyob rau hauv lub xub ntiag ntawm ib tug catalyst, ethylene yog oxidized los ntawm oxygen nyob rau hauv cov huab cua los tsim benzaldehyde.

 

Cov ntaub ntawv kev nyab xeeb:

- Nws muaj cov tshuaj toxicity tsawg thiab tsis ua rau muaj teeb meem kev noj qab haus huv rau tib neeg raws li kev siv ib txwm muaj.

- Nws yog khaus rau qhov muag thiab tawv nqaij, thiab kev tiv thaiv xws li hnab looj tes thiab tsom iav yuav tsum tau noj thaum kov.

- Ntev ntev mus rau qhov siab siab ntawm benzaldehyde vapor yuav ua rau khaus rau hauv lub ntsws thiab lub ntsws, thiab kev nqus pa ntev yuav tsum zam.

- Thaum tuav benzaldehyde, yuav tsum tau saib xyuas rau qhov hluav taws kub thiab qhov cua kom tsis txhob raug hluav taws kub los yog kub.
