1,Taw qhia

Hauv thaj chaw ntawm chemistry,phenolyog ib qho tseem ceeb sib xyaw siv dav hauv ntau yam xws li tshuaj, kev ua liaj ua teb, thiab kev lag luam.Rau cov kws tshaj lij tshuaj, nws yog ib qho tseem ceeb kom nkag siab txog ntau hom phenols.Txawm li cas los xij, rau cov kws tshaj lij, kev nkag siab cov lus teb rau lo lus nug no tuaj yeem pab lawv nkag siab zoo txog ntau yam kev siv phenol.

2,Lub ntsiab hom phenol

1. Monophenol: Qhov no yog daim ntawv yooj yim tshaj plaws ntawm phenol, tsuas yog ib lub nplhaib benzene thiab ib pawg hydroxyl.Monophenol tuaj yeem nthuav tawm cov khoom sib txawv nyob ntawm qhov hloov pauv.

2. Polyphenol: Hom phenol no muaj ntau lub nplhaib benzene.Piv txwv li, ob qho tib si bisphenol thiab triphenol yog ntau polyphenols.Cov tebchaw no feem ntau muaj ntau yam tshuaj lom neeg thiab kev siv.

3. Hloov phenol: Hauv hom phenol no, pawg hydroxyl hloov los ntawm lwm cov atoms lossis atomic pawg.Piv txwv li, chlorophenol, nitrophenol, thiab lwm yam yog cov hloov phenols.Cov tebchaw no feem ntau muaj cov tshuaj tshwj xeeb thiab kev siv.

4. Polyphenol: Hom phenol no yog tsim los ntawm ntau lub phenol units txuas ua ke los ntawm kev sib txuas tshuaj.Polyphenol feem ntau muaj lub cev tshwj xeeb thiab kev ruaj ntseg tshuaj.

3,Ntau hom phenol

Yuav kom meej meej, cov lus nug ntawm pes tsawg hom phenols muaj yog ib lo lus nug uas tsis teb, raws li cov txheej txheem synthesis tshiab tau raug tshawb pom tas li thiab cov phenols tshiab tau los ua ke.Txawm li cas los xij, rau tam sim no paub hom phenols, peb tuaj yeem faib thiab npe raws li lawv cov qauv thiab cov khoom.

4,Xaus

Zuag qhia tag nrho, tsis muaj lus teb meej rau cov lus nug ntawm pes tsawg hom phenols muaj.Txawm li cas los xij, peb tuaj yeem faib cov phenols rau ntau hom raws li lawv cov qauv thiab cov khoom, xws li monophenols, polyphenols, hloov phenols, thiab polymeric phenols.Cov phenols sib txawv no muaj qhov sib txawv ntawm lub cev thiab tshuaj lom neeg thiab tau siv dav hauv ntau yam xws li tshuaj, kev ua liaj ua teb, thiab kev lag luam.
