Phenolyog ib qho tseem ceeb heev cov khoom siv raw, uas yog dav siv nyob rau hauv kev tsim cov tshuaj lom neeg, xws li cov roj hmab, tshuaj, nws yog qhov tseem ceeb heev kom paub cov ntaub ntawv raw rau phenol.

Cov khoom siv raw rau phenol ntau lawm suav nrog benzene, methanol thiab sulfuric acid. Benzene yog ib qho tseem ceeb heev cov khoom siv raw, uas tuaj yeem siv los tsim ntau yam tshuaj chemical, xws li Phenol, Anetophenone thiab lwm yam. Methanol yog ib qho tseem ceeb organic raw khoom, uas tuaj yeem siv los ua ntau yam sib xyaw ua ke nrog oxygen-muaj cov pab pawg ua haujlwm. Sulfuric acid yog ib qho tseem ceeb inorganic acid, uas yog dav siv hauv kev lag luam tshuaj thiab lwm yam kev lag luam.

Cov txheej txheem ua cov phenol ntawm benzene, methanol thiab sulfuric acid yog qhov nyuaj heev. Firstly, Benzene thiab Methanol tau hnov ​​qab nyob rau hauv kev txiav txim ntawm catalyst los tsim cov cumene. Tom qab ntawd, cumene yog oxidized nyob rau hauv lub xub ntiag ntawm huab cua los ua cumene hydroperoxide. Thaum kawg, cumene hydroperoxide yog reacted nrog diluted sulfuric acid los ua cov phenol thiab acetone.

Nyob rau hauv cov txheej txheem ntawm kev tsim phenol, kev xaiv ntawm catalyst tseem ceeb heev. Cov catalalys feem ntau yog suav nrog txhuas chloride, sulfuric acid thiab phosphoric acid. Tsis tas li ntawd, cov txheej txheem mob xws li kub, lub siab thiab cov siab tseem cuam tshuam cov txiaj ntsig thiab qhov zoo ntawm cov khoom.

Feem ntau, cov khoom siv raw rau phenol ntau lawm yog qhov nyuaj, thiab cov txheej txheem cov txheej txheem yog kom nruj. Txhawm rau kom tau txais cov khoom lag luam zoo thiab cov khoom lag luam siab, nws yog qhov tsim nyog kom tswj tau cov khoom siv raw ua kom zoo thiab ua cov xwm txheej. Ib qho ntxiv, nws tseem yuav tsum tau coj mus rau hauv cov nyiaj kev tiv thaiv ib puag ncig thiab kev nyab xeeb hauv cov txheej txheem ntau lawm. Yog li ntawd, thaum siv phenol ua cov khoom siv raw los ua cov khoom lag luam ntau yam kom ntseeg tau tias peb tuaj yeem tau txais cov khoom lag luam zoo thiab muaj txiaj ntsig zoo thaum ib puag ncig thiab kev nyab xeeb.
