Taw qhia

Phenol, tseem hu ua hydroxybenzene, 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 phenol:

 

Zoo:

- Cov tsos: Xim tsis muaj xim rau dawb crystalline khoom.

- Solubility: Soluble nyob rau hauv dej thiab feem ntau cov organic solvents.

- Cov ntxhiab tsw: muaj qhov tshwj xeeb phenolic tsw.

- Reactivity: Phenol yog cov kua qaub-puag nruab nrab thiab tuaj yeem ua rau cov tshuaj tiv thaiv acid-puag, cov tshuaj tiv thaiv oxidation, thiab hloov cov tshuaj tiv thaiv nrog lwm cov tshuaj.

 

Siv:

- Kev lag luam tshuaj: Phenol yog dav siv nyob rau hauv cov synthesis ntawm cov tshuaj xws li phenolic aldehyde thiab phenol ketone.

- Cov tshuaj tua kab mob: Phenol tuaj yeem siv ua cov tshuaj tua kab mob, tshuaj tua kab mob, thiab tshuaj tua kab mob.

- Roj hmab kev lag luam: tuaj yeem siv los ua cov roj hmab ntxiv los txhim kho cov viscosity ntawm roj hmab.

 

Txoj kev:

- Ib txoj hauv kev zoo rau kev npaj phenol yog los ntawm oxidation ntawm oxygen hauv huab cua. Phenol kuj tseem tuaj yeem npaj los ntawm cov tshuaj tiv thaiv demethylation ntawm catechols.

 

Cov ntaub ntawv kev nyab xeeb:

- Phenol muaj qee yam toxicity thiab muaj kev cuam tshuam rau ntawm daim tawv nqaij, qhov muag thiab ua pa. Yaug nrog dej tam sim ntawd tom qab kis tau thiab nrhiav kev kho mob sai.

- Kev raug cov phenol ntau ntau tuaj yeem ua rau muaj cov tsos mob lom, xws li kiv taub hau, xeev siab, ntuav, thiab lwm yam. Kev raug mob mus ntev tuaj yeem ua rau lub siab, ob lub raum, thiab lub paj hlwb puas.

- Thaum lub sijhawm khaws cia thiab siv, yuav tsum tau ntsuas kev nyab xeeb tsim nyog xws li hnav hnab looj tes tiv thaiv, tsom iav, thiab lwm yam. Ua haujlwm nyob rau hauv qhov chaw zoo ventilated.
