Phenol yog ib qho tseem ceeb heev organic tshuaj raw khoom nrog ntau cov kev siv. Nws txoj kev lag luam tsim khoom yog qhov txaus siab rau cov kws tshawb nrhiav thiab cov chaw tsim khoom. Muaj ob txoj kev tseem ceeb rau kev ua lag luam phenol, uas yog: cov txheej txheem cumene thiab cov txheej txheem CRESOL.

Cov txheej txheem cumene yog qhov feem ntau siv cov qauv kev lag luam rau phenol. Nws cuam tshuam nrog cov tshuaj tiv thaiv ntawm bumene nrog benzene nyob rau hauv lub xub ntiag ntawm ib acid catalyst los tsim cumene hydroperoxide. Lub hydroperoxide yog tom qab ntawd reacted nrog lub zog muaj zog xws li sodium hydroxide los tsimphenolthiab acetone. Lub ntsiab kom zoo dua ntawm cov txheej txheem no yog tias nws siv cov khoom siv raw thiab cov kev tshuaj tiv thaiv kuj muaj mob hnyav, ua rau nws muaj txiaj ntsig thiab yooj yim tswj. Yog li ntawd, cov txheej txheem cumene yog dav siv nyob rau hauv kev tsim cov phenol.

Cov txheej txheem cresol yog qhov tsis tshua siv kev lag luam txoj kev ua lag luam rau phenol. Nws cuam tshuam nrog cov tshuaj tiv thaiv ntawm Toluene nrog methanol nyob rau hauv lub xub ntiag ntawm ib acid catalyst los tsim cresol. Lub cresol yog ces hydrogenated nyob rau hauv muaj ntawm catalyst xws li platinum lossis palladium los tsim cov phenol. Lub ntsiab kom zoo dua ntawm cov txheej txheem no yog tias nws siv cov khoom siv raw thiab cov kev tshuaj tiv thaiv mob hnyav thiab yuav tsum muaj ntau cov khoom siv thiab cov kauj ruam. Tsis tas li ntawd, cov txheej txheem CRESOL tsim cov nyiaj ntau ntawm cov khoom lag luam, uas txo nws txoj kev khwv nyiaj txiag. Yog li, cov qauv no tsis yog siv nyob rau hauv kev tsim cov phenol.

Hauv cov ntsiab lus, muaj ob txoj hauv kev rau kev ua lag luam ntau lawm ntawm Phenol: Cov txheej txheem cumene thiab txheej txheem CRESOL. Cov txheej txheem cumene yog siv dav siv vim tias nws siv pheej yig raw cov ntaub ntawv, muaj cov tshuaj tiv thaiv me me, thiab yog qhov yooj yim los tswj. Cov txheej txheem cresol tsis tshua siv vim tias nws yuav tsum muaj ntau cov khoom siv thiab cov kauj ruam, muaj ntau cov txheej txheem nyuaj, txo nws cov khoom lag luam loj, txo nws txoj kev khwv nyiaj txiag. Yav tom ntej, cov txheej txheem tshiab thiab cov txheej txheem yuav raug tsim los txhim kho kev ua tau zoo thiab txo cov nqi ntawm kev tsim khoom, qhib kev lag luam tshiab rau kev lag luam phenol.
