Taw qhia
3,4-Xylenol, tseem hu ua m-xylenol, yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 3,4-xylenol:
Zoo:
- 3,4-Xylenol yog cov kua tsis muaj xim uas muaj ntxhiab tsw tshwj xeeb.
- Nws muaj cov cuab yeej soluble hauv dej thiab ntau cov kuab tshuaj organic.
- Pom zoo li cov qauv transverse dimer ntawm chav tsev kub.
Siv:
- Nws yog siv los ua cov tshuaj tua kab mob thiab tshuaj tua kab mob hauv cov tshuaj fungicides thiab tshuaj tua kab mob.
- Siv los ua ib qho catalyst hauv qee cov tshuaj synthesis tshuaj.
Txoj kev:
- 3,4-Xylenol tuaj yeem npaj los ntawm cov tshuaj tiv thaiv condensation ntawm phenol thiab formaldehyde nyob rau hauv acidic tej yam kev mob.
- Hauv cov tshuaj tiv thaiv, phenol thiab formaldehyde yog catalyzed los ntawm acidic catalyst los tsim 3,4-xylenol.
Cov ntaub ntawv kev nyab xeeb:
- 3,4-Xylenol muaj cov tshuaj toxicity tsawg, tab sis nws tseem ceeb heev uas yuav tsum siv nws kom nyab xeeb.
- Vapors lossis tshuaj tsuag tuaj yeem ua rau khaus thiab ua rau lub qhov muag thiab tawv nqaij.
- Thaum ua haujlwm, siv cov cuab yeej tiv thaiv tus kheej tsim nyog, xws li cov hnab looj tes tshuaj thiab tsom iav.
- Thaum khaws cia thiab tuav 3,4-xylenol, nws yog ib qho tseem ceeb kom tswj cov khoom pov tseg kom tsis txhob muaj kuab paug ib puag ncig.
