Taw qhia

2,6-dimethylpyridine 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 2,6-dimethylpyridine:

 

Zoo:

2,6-Dimethylpyridine yog cov kua xim tsis muaj xim nrog cov ntxhiab tsw muaj zog.

 

Siv:

2,6-Dimethylpyridine muaj ntau yam kev siv:

1. Nws tuaj yeem siv los ua ib qho catalyst thiab reagent hauv cov organic synthesis cov tshuaj tiv thaiv.

2. Nws yog siv los ua raw khoom rau kev npaj dyes, fluorescents thiab organic cov ntaub ntawv.

3. Siv raws li hnyav thiab extractant, dav siv nyob rau hauv tej tshuaj lom neeg cov tshuaj tiv thaiv thiab kev lag luam kws.

 

Txoj kev:

2,6-Dimethylpyridine feem ntau yog tsim los ntawm cov tshuaj tiv thaiv ntawm acetophenone thiab ethyl methyl acetate.

 

Cov ntaub ntawv kev nyab xeeb:

1. Nws muaj cov ntxhiab tsw ntxhiab thiab yuav tsum zam kom tsis txhob sib cuag ntev thiab tsis txhob nqus cov pa los yog vapors.

2. Cov hnab looj tes tiv thaiv tsim nyog, tsom iav thiab khaub ncaws tiv thaiv yuav tsum hnav thaum ua haujlwm.

3. Tsis txhob sib cuag nrog cov oxidants muaj zog thiab muaj zog acids kom tsis txhob muaj kev phom sij txaus ntshai.

4. Thaum khaws cia, lub thawv yuav tsum kaw kom nruj, kom deb ntawm qhov hluav taws kub thiab ib puag ncig kub.
