Taw qhia

3,5-Dimethylphenol (tseem hu ua m-dimethylphenol) yog cov organic compound. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:

 

Zoo:

- Cov tsos mob: 3,5-dimethylphenol yog dawb crystalline khoom.

- Solubility: Nws yog soluble hauv cawv thiab ether thiab me ntsis soluble hauv dej.

- Cov ntxhiab tsw: muaj ntxhiab tsw tshwj xeeb.

- Cov khoom siv tshuaj: Nws yog ib qho phenolic compound nrog universal zog ntawm phenol. Nws tuaj yeem oxidized los ntawm oxidizing cov neeg ua haujlwm thiab cov tshuaj tiv thaiv xws li esterification, alkylation, thiab lwm yam tuaj yeem tshwm sim.

 

Siv:

- Tshuaj reagents: 3,5-dimethylphenol feem ntau yog siv los ua reagent hauv cov organic synthesis hauv cov chaw kuaj mob.

 

Txoj kev:

3,5-Dimethylphenol tuaj yeem npaj los ntawm:

Dimethylbenzene yog tau los ntawm reacting nrog bromine nyob rau hauv alkaline tej yam kev mob thiab ces kho nrog acid.

Dimethylbenzene yog kho nrog acid thiab tom qab ntawd oxidized.

 

Cov ntaub ntawv kev nyab xeeb:

- Kev sib cuag nrog daim tawv nqaij yuav ua rau khaus thiab ua xua, hnav cov khoom tiv thaiv tus kheej thaum siv nws.

- Thaum nqus tau los yog nqus tau ntau dhau, nws tuaj yeem ua rau muaj cov tsos mob lom, xws li kiv taub hau, xeev siab, ntuav, thiab lwm yam. Yuav tsum tau ceev faj kom tsis txhob muaj kev sib tsoo lossis nqus pa thaum tuav.

- Thov xa mus rau cov ntaub ntawv pov thawj kev nyab xeeb thiab cov lus qhia ua haujlwm rau kev siv thiab tuav kom raug.
