Taw qhia

2-Chlorobenzaldehyde yog ib qho organic compound. Hauv qab no yog kev qhia txog qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2-chloromicidal ketone:

 

Zoo:

- Cov tsos mob: 2-chloromicidalone yog cov kua tsis muaj xim rau daj ntseg daj.

- Solubility: Nws tuaj yeem yaj hauv cov kuab tshuaj organic xws li cawv, ethers, thiab ketones.

 

Siv:

-Rodenticide: 2-chloromicide yog tshuaj tua kab mob uas tuaj yeem siv los tswj cov kab tsuag nas.

- Tshuaj intermediates: Nws kuj siv tau los ua ib qho nruab nrab hauv cov organic synthesis los npaj lwm cov tebchaw.

 

Txoj kev:

2-chlorocidalone tuaj yeem tau txais los ntawm chlorination ntawm benzaldehyde thiab chlorine gas.

 

Cov ntaub ntawv kev nyab xeeb:

- 2-chlorochlorocidal ua rau khaus thiab tuaj yeem tsim kev puas tsuaj rau daim tawv nqaij thiab qhov muag. Kev tiv thaiv tsim nyog xws li hnab looj tes thiab tsom iav yuav tsum hnav thaum siv.

- Tsis txhob nqus, zom, lossis noj 2-chloromicidalone thaum tuav, khaws cia, lossis siv.

- Thaum siv, yuav tsum tau saib xyuas kom tsis txhob sib cuag nrog cov khoom siv hluav taws xob tiv thaiv hluav taws los yog tawg.

- 2-Chloromicidalone yuav tsum muab cia rau hauv qhov chaw txias, qhuav, deb ntawm hluav taws thiab oxidants.

- Ua raws li cov txheej txheem kev nyab xeeb thiab cov cai hauv zos thaum siv lossis pov tseg 2-chloromicidalone.

Thaum siv lossis ua haujlwm 2-chloromicidalone, yuav tsum tau ua raws li cov lus qhia thiab kev nyab xeeb, thiab cov ntaub ntawv qhia txog kev nyab xeeb uas muab los ntawm cov neeg muab khoom yuav tsum tau sab laj.
