1,Lub hauv paus rau phau ntawv

Hauv kev thaj teb ntawm chemistry,phenolyog ib qho tseem ceeb compound dav siv nyob rau hauv ntau daim teb xws li tshuaj, kev ua liaj ua teb, thiab kev lag luam. Rau cov kws tshaj lij tshuaj lom neeg, nws yog qhov tseem ceeb kom nkag siab txog ntau hom phenols. Txawm li cas los xij, rau cov kws tshaj lij, nkag siab cov lus teb rau cov lus nug no yuav pab lawv nkag siab zoo dua cov kev siv Phenol ntau yam.

2,Lub ntsiab ntawm phenol

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

2. Polyphenol: Hom phenol no muaj ntau lub rings. Piv txwv li, ob qho tib si Bisphenol thiab Triphenol yog cov polyphenols. Cov tebchaw no feem ntau muaj cov tshuaj sib ntxiv cov tshuaj thiab cov ntawv thov.

3. Tsuav Phaj: Hauv Phenol no, cov pab pawg hydroxyl yog hloov los ntawm lwm cov atoms lossis cov pab pawg atomic. Piv txwv li, chlorophenol, nitrophenol, thiab lwm yam yog hloov cov phenols. Cov tebchaw no feem ntau muaj cov tshuaj lom neeg tshwj xeeb thiab kev siv.

4. Polyphenol: Hom phenol no yog tsim los ntawm ntau cov chav phenol txuas nrog ua ke los ntawm kev sib txuas lus lom neeg. Polyphenol feem ntau muaj cov yam ntxwv tshwj xeeb lub cev thiab tshuaj lom neeg ruaj khov.

3,Kom muaj nuj nqis phenol hom

Yuav kom muaj tseeb, cov lus nug ntawm ntau hom phenols muaj yog ib qho lus nug tsis muaj, raws li cov phenholars tshiab tau tas mus li thiab tshiab ntawm phenols tau tas li yog synthesized tas li. Txawm li cas los xij, rau cov hom phenols tam sim no, peb tuaj yeem faib thiab npe lawv raws li lawv cov qauv thiab cov khoom.

4,Tag

Zuag qhia tag nrho, tsis muaj cov lus teb meej rau cov lus nug ntawm ntau hom phenols muaj. Txawm li cas los xij, peb tuaj yeem cais cov phenols mus rau ntau hom raws li lawv cov qauv thiab cov qauv, xws li cov monophenols, pycyres, hloov phenols, thiab polymerican phenols. Cov phenol ntau hom nyias muaj nyias lub cev thiab tshuaj lom neeg thiab tau siv dav hauv ntau thaj teb xws li tshuaj, kev ua liaj ua teb, thiab kev lag luam.
