Phenolndi mankhwala osiyanasiyana omwe amagwiritsidwa ntchito mosiyanasiyana mumakampani ndi kafukufuku. Kukonzekera kwake kwamalonda kumaphatikizapo njira zambiri zomwe zimayambira ndi okosijeni wa cyclohexane. Pochita izi, cyclohexane imapangidwa ndi oxidized mu mndandanda wa intermediates, kuphatikizapo cyclohexanol ndi cyclohexanone, zomwe zimasinthidwa kukhala phenol. Tiyeni tifufuze tsatanetsatane wa ndondomekoyi. 

Kukonzekera kwamalonda kwa phenol kumayamba ndi makutidwe ndi okosijeni a cyclohexane. Izi zimachitika pamaso pa oxidizing wothandizira, monga mpweya kapena mpweya woyera, ndi chothandizira. Chothandizira chomwe chimagwiritsidwa ntchito pochita izi nthawi zambiri chimakhala chosakaniza zitsulo zosinthika, monga cobalt, manganese, ndi bromine. Zomwe zimachitika pa kutentha kwakukulu ndi kupanikizika, nthawi zambiri kuyambira 600 mpaka 900.°C ndi 10 mpaka 200 atmospheres, motero.

The makutidwe ndi okosijeni wa cyclohexane kumabweretsa mapangidwe angapo intermediates, kuphatikizapo cyclohexanol ndi cyclohexanone. Izi intermediates kenako n'kukhala phenol mu wotsatira anachita sitepe. Izi zimachitika pamaso pa chothandizira asidi, monga sulfuric acid kapena hydrochloric acid. The asidi chothandizira amalimbikitsa kuchepa madzi m`thupi wa cyclohexanol ndi cyclohexanone, chifukwa mapangidwe phenol ndi madzi.

Zotsatira za phenol zimatsukidwa ndi distillation ndi njira zina zoyeretsera kuchotsa zonyansa ndi zina zowonjezera. Njira yoyeretsera imatsimikizira kuti chomaliza chimakwaniritsa zofunikira za chiyero cha ntchito zosiyanasiyana.

Phenol imagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikiza kupanga ma polycarbonates, Bisphenol A (BPA), ma phenolic resins, ndi mankhwala ena osiyanasiyana. Ma polycarbonates amagwiritsidwa ntchito kwambiri popanga zotengera zapulasitiki, magalasi, ndi zinthu zina zowoneka bwino chifukwa chowonekera kwambiri komanso kukana kukhudzidwa. BPA imagwiritsidwa ntchito popanga ma epoxy resins ndi zomatira zina, zokutira, ndi zophatikiza. Phenolic resins amagwiritsidwa ntchito popanga zomatira, zokutira, ndi zophatikizika chifukwa cha kukana kwawo kutentha ndi mankhwala.

Pomaliza, kukonzekera kwamalonda kwa phenol kumaphatikizapo okosijeni wa cyclohexane, kutsatiridwa ndi kutembenuka kwapakati kukhala phenol ndi kuyeretsedwa kwa mankhwala omaliza. Zotsatira zake za phenol zimagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo kupanga zotengera zapulasitiki, zomatira, zokutira, ndi zophatikiza.
