Phenol yog ib hom organic compound nrog benzene nplhaib qauv. Nws yog xim tsis muaj pob tshab lossis kua nplaum uas muaj cov yam ntxwv iab saj thiab tsw ntxhiab tsw. Nws yog me ntsis soluble hauv dej, soluble hauv ethanol thiab ether, thiab yooj yim soluble hauv benzene, toluene thiab lwm yam organic solvents. Phenol yog cov khoom siv tseem ceeb hauv kev lag luam tshuaj thiab tuaj yeem siv rau kev sib txuas ntawm ntau lwm cov tebchaw, xws li plasticizers, dyes, herbicides, lubricants, surfactants thiab adhesives. Yog li ntawd, phenol yog dav siv nyob rau hauv zus tau tej cov industries. Tsis tas li ntawd, phenol kuj yog ib qho tseem ceeb nruab nrab ntawm kev lag luam kws tshuaj, uas tuaj yeem siv los tsim ntau yam tshuaj xws li tshuaj aspirin, penicillin, streptomycin thiab tetracycline. Yog li ntawd, qhov kev thov rau phenol yog loj heev nyob rau hauv kev ua lag luam.
Lub hauv paus tseem ceeb ntawm phenol yog thee tar, uas tuaj yeem muab rho tawm los ntawm cov txheej txheem thee tar distillation. Tsis tas li ntawd, phenol kuj tuaj yeem ua ke los ntawm ntau txoj hauv kev, xws li decomposition ntawm benzene thiab toluene nyob rau hauv lub xub ntiag ntawm catalysts, hydrogenation ntawm nitrobenzene, txo cov phenolsulfonic acid, thiab lwm yam. Ntxiv nrog rau cov txheej txheem no, phenol kuj tuaj yeem ua tau. tau los ntawm decomposition ntawm cellulose los yog qab zib nyob rau hauv kub thiab siab tej yam kev mob.
Ntxiv rau cov txheej txheem saum toj no, phenol kuj tuaj yeem tau txais los ntawm kev rho tawm ntawm cov khoom ntuj xws li tshuaj yej nplooj thiab taum taum. Nws yog tsim nyog hais tias cov txheej txheem extraction ntawm tshuaj yej nplooj thiab cocoa taum tsis muaj kuab paug rau ib puag ncig thiab kuj yog ib qho tseem ceeb txoj kev kom tau txais phenol. Tib lub sijhawm, cocoa taum kuj tuaj yeem tsim lwm cov khoom tseem ceeb rau kev sib txuas ntawm plasticizers - phthalic acid. Yog li ntawd, cocoa taum kuj yog ib qho tseem ceeb raw khoom rau zus tau tej cov plasticizers.
Feem ntau, phenol yog siv dav hauv ntau lub lag luam thiab muaj kev lag luam zoo heev. Txhawm rau kom tau txais cov khoom lag luam phenol zoo, peb yuav tsum tau ua tib zoo xaiv cov khoom siv raw thiab cov txheej txheem txheej txheem hauv cov txheej txheem tsim khoom kom ntseeg tau tias cov khoom ua tau raws li cov qauv thiab cov kev cai.
