I-phenol sisixhobo esibaluleke kakhulu semichiza esingu-sponyis esiluhlaza esinezinto ezibanzi zezicelo. Iindlela zayo zemveliso zorhwebo zinomdla omkhulu kubaphandi kunye nabavelisi. Zimbini iindlela eziphambili zemveliso yorhwebo ye-phenol, eziyi: Inkqubo yeCumene kunye nenkqubo yeCres.

Inkqubo yeCumene yeyona ndlela isetyenziswa kakhulu yemveliso yemveliso ye-phenol. Kubandakanya ukuphendula kwe-cumene nge-bedzene phambi kwe-acid catalytst ukuvelisa i-cumene hydroperoperothide. I-hydroperaperoxide ke iphinda iphinde ihlawulwe kwisiseko esomeleleyo esifana neSodium hydroxide ukuba ivelisephenolne-acetone. Eyona nto iphambili kule nkqubo kukuba isebenzisa izixhobo ezingabizi kakhulu kwaye iimeko zokuphendula zinobulali, zisenza ngokufanelekileyo kwaye kulula ukuzilawula. Ke ngoko, inkqubo ye-cumbine isetyenziswa ngokubanzi kwimveliso ye-phenol.

Inkqubo yeCres yindlela encinci yemveliso esetyenziswayo yemveliso ye-phenol. Kubandakanya ukusabela kwe-toluene e-methanol phambi kwe-acid catalyst ukuvelisa i-Cres. I-Cres i-hredrogeniged ke i-hydrogenid phambi kobuso obufana neplatinam okanye i-pilladium ivelise i-phenol. Eyona nto iphambili kuyo le nkqubo kukuba isebenzisa izixhobo ezingabizi kakhulu kwaye iimeko zokuphendula zinobulali, kodwa le nkqubo inzima kwaye ifuna izixhobo kunye namanyathelo. Ukongeza, inkqubo ye-Cres ivelisa inani elikhulu lemveliso, enciphisa ukusebenza kakuhle kwezoqoqosho. Ke ngoko, le ndlela ayisetyenziswanga esetyenziswayo kwimveliso ye-phenol.

Isishwankathelo, zimbini iindlela eziphambili zemveliso yorhwebo ye-phenol: Inkqubo yeCumene kunye nenkqubo yeCres. Inkqubo ye-cumene isetyenziswa ngokubanzi kuba isebenzisa izixhobo ezingabizi kakhulu, zineemeko ezibonakalayo, kwaye kulula ukulawula. Inkqubo ye-Cres isetyenziswa kancinci kuba ifuna izixhobo kunye namanyathelo, inenkqubo entsonkothileyo, kwaye ivelise inani elikhulu leemveliso ze-ofisi, ukunciphisa ukusebenza kakuhle kwezoqoqosho. Kwixa elizayo, itekhnoloji entsha kunye neenkqubo zinokuphuhliswa ukuphucula ukusebenza nokunciphisa iindleko zemveliso, ukuvula amathuba amatsha kwimveliso yezorhwebo ye-phenol.
