Phenol yog ib qho tseem ceeb heev organic raw khoom nrog ntau yam kev siv.Nws txoj kev tsim khoom lag luam muaj txiaj ntsig zoo rau cov kws tshawb fawb thiab cov tuam ntxhab.Muaj ob txoj hauv kev tseem ceeb rau kev ua lag luam ntawm phenol, uas yog: txheej txheem cumene thiab txheej txheem cresol.

Cov txheej txheem cumene yog cov kev lag luam siv ntau tshaj plaws rau phenol.Nws koom nrog cov tshuaj tiv thaiv ntawm cumene nrog benzene nyob rau hauv muaj cov kua qaub catalyst los tsim cumene hydroperoxide.Tom qab ntawd cov hydroperoxide yog reacted nrog lub hauv paus 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 pheej yig heev thiab cov kev mob tshwm sim kuj yog me me, ua rau nws muaj txiaj ntsig thiab tswj tau yooj yim.Yog li ntawd, cov txheej txheem cumene yog dav siv nyob rau hauv zus tau tej cov phenol.

Cov txheej txheem cresol yog ib qho kev lag luam uas tsis tshua siv rau kev tsim khoom rau phenol.Nws koom nrog cov tshuaj tiv thaiv ntawm toluene nrog methanol nyob rau hauv muaj cov kua qaub catalyst los tsim cresol.Lub cresol yog hydrogenated nyob rau hauv lub xub ntiag ntawm ib tug catalyst xws li platinum los yog palladium los tsim phenol.Lub ntsiab kom zoo dua ntawm cov txheej txheem no yog tias nws siv cov khoom siv pheej yig heev thiab cov kev mob tshwm sim kuj yog me me, tab sis cov txheej txheem yog qhov nyuaj thiab yuav tsum tau siv ntau yam khoom thiab cov kauj ruam.Tsis tas li ntawd, cov txheej txheem cresol tsim ntau cov khoom los ntawm cov khoom lag luam, uas txo nws cov txiaj ntsig kev lag luam.Yog li ntawd, txoj kev no tsis yog feem ntau siv hauv kev tsim cov phenol.

Hauv cov ntsiab lus, muaj ob txoj hauv kev tseem ceeb rau kev ua lag luam ntawm phenol: cov txheej txheem cumene thiab cov txheej txheem cresol.Cov txheej txheem cumene tau dav siv vim nws siv cov khoom siv pheej yig, muaj cov tshuaj tiv thaiv me me, thiab yooj yim los tswj.Cov txheej txheem cresol tsis tshua siv vim nws xav tau cov cuab yeej siv ntau dua thiab cov kauj ruam, muaj cov txheej txheem nyuaj, thiab tsim cov khoom lag luam ntau, txo nws cov txiaj ntsig kev lag luam.Nyob rau hauv lub neej yav tom ntej, tshiab technologies thiab cov txheej txheem tej zaum yuav raug tsim los txhim kho cov efficiency thiab txo tus nqi ntawm ntau lawm, qhib tshiab possibilities rau kev lag luam ntau lawm ntawm phenol.
