Phenolyog ntau yam tshuaj sib xyaw nrog ntau yam kev siv hauv kev lag luam thiab kev tshawb fawb.Nws txoj kev npaj ua lag luam suav nrog ntau cov txheej txheem uas pib nrog oxidation ntawm cyclohexane.Nyob rau hauv cov txheej txheem no, cyclohexane yog oxidized rau hauv ib tug series ntawm intermediates, xws li cyclohexanol thiab cyclohexanone, uas yog ces hloov mus rau hauv phenol.Wb delve rau hauv cov ntsiab lus ntawm cov txheej txheem no. 

Kev lag luam npaj ntawm phenol pib nrog oxidation ntawm cyclohexane.Cov tshuaj tiv thaiv no yog nqa tawm nyob rau hauv lub xub ntiag ntawm ib tug oxidizing neeg sawv cev, xws li huab cua los yog ntshiab oxygen, thiab ib tug catalyst.Cov catalyst siv rau hauv cov tshuaj tiv thaiv no feem ntau yog sib xyaw ntawm cov hlau hloov pauv, xws li cobalt, manganese, thiab bromine.Cov tshuaj tiv thaiv yog nqa tawm ntawm qhov kub thiab txias, feem ntau yog li ntawm 600 txog 900.°C thiab 10 txog 200 atmospheres, feem.

Lub oxidation ntawm cyclohexane ua rau muaj kev tsim ntawm ib tug series ntawm intermediates, xws li cyclohexanol thiab cyclohexanone.Cov intermediates no ces hloov mus rau hauv phenol hauv cov kauj ruam tom ntej.Cov tshuaj tiv thaiv no yog ua nyob rau hauv lub xub ntiag ntawm ib tug acid catalyst, xws li sulfuric acid los yog hydrochloric acid.Cov kua qaub catalyst txhawb lub cev qhuav dej ntawm cyclohexanol thiab cyclohexanone, uas ua rau tsim cov phenol thiab dej.

Qhov tshwm sim phenol yog ces purified los ntawm distillation thiab lwm yam purification txheej txheem kom tshem tawm impurities thiab lwm yam by-products.Cov txheej txheem purification ua kom ntseeg tau tias cov khoom kawg ua tau raws li qhov xav tau purity rau ntau daim ntawv thov.

Phenol yog siv nyob rau hauv ntau yam kev siv, nrog rau kev tsim cov polycarbonates, Bisphenol A (BPA), phenolic resins, thiab ntau lwm cov tebchaw.Polycarbonates tau siv dav hauv kev tsim cov thawv yas, lo ntsiab muag, thiab lwm yam khoom siv kho qhov muag vim lawv cov pob tshab siab thiab tiv thaiv kev cuam tshuam.BPA yog siv los tsim cov epoxy resins thiab lwm yam nplaum, txheej, thiab cov khoom sib xyaw.Phenolic resins yog siv nyob rau hauv zus tau tej cov adhesives, coatings, thiab composites vim lawv siab tsis kam mus rau tshav kub thiab tshuaj.

Hauv kev xaus, kev lag luam kev npaj ntawm phenol suav nrog oxidation ntawm cyclohexane, tom qab ntawd los ntawm kev hloov pauv ntawm intermediates rau hauv phenol thiab purification ntawm cov khoom kawg.Cov txiaj ntsig phenol yog siv rau ntau yam kev siv, suav nrog kev tsim cov ntim yas, cov nplaum, txheej, thiab cov khoom sib xyaw.
