Phenol ndi yofunika kwambiri organic mankhwala zopangira ndi osiyanasiyana ntchito.Njira zake zopangira malonda ndizosangalatsa kwambiri kwa ofufuza ndi opanga.Pali njira ziwiri zazikulu zopangira malonda a phenol, zomwe ndi: ndondomeko ya cumene ndi ndondomeko ya cresol.

Njira ya cumene ndiyo njira yomwe imagwiritsidwa ntchito kwambiri popanga malonda a phenol.Zimakhudza momwe cumene alili ndi benzene pamaso pa asidi chothandizira kupanga cumene hydroperoxide.The hydroperoxide ndiye anachita ndi maziko amphamvu monga sodium hydroxide kupangaphenolndi acetone.Ubwino waukulu wa njirayi ndikuti umagwiritsa ntchito zopangira zotsika mtengo komanso momwe zinthu zimachitikira ndizochepa, zomwe zimapangitsa kuti zikhale zosavuta komanso zosavuta kuziwongolera.Choncho, ndondomeko ya cumene imagwiritsidwa ntchito kwambiri popanga phenol.

Njira ya cresol ndi njira yosagwiritsidwa ntchito kwambiri popanga malonda a phenol.Zimakhudza momwe toluene ndi methanol pamaso pa asidi chothandizira kupanga cresol.The cresol ndiye hydrogenated pamaso pa chothandizira monga platinamu kapena palladium kupanga phenol.Ubwino waukulu wa njirayi ndikuti umagwiritsa ntchito zopangira zotsika mtengo komanso momwe zinthu zimachitikira ndizochepa, koma njirayi ndi yovuta kwambiri ndipo imafuna zida ndi masitepe.Kuonjezera apo, ndondomeko ya cresol imapanga zinthu zambiri zomwe zimapangidwira, zomwe zimachepetsa mphamvu zake zachuma.Choncho, njirayi sigwiritsidwa ntchito kawirikawiri popanga phenol.

Mwachidule, pali njira ziwiri zazikulu zopangira malonda a phenol: ndondomeko ya cumene ndi ndondomeko ya cresol.Njira ya cumene imagwiritsidwa ntchito kwambiri chifukwa imagwiritsa ntchito zipangizo zotsika mtengo, imakhala ndi machitidwe ochepa, ndipo ndi yosavuta kulamulira.Njira ya cresol siigwiritsidwa ntchito kawirikawiri chifukwa imafuna zipangizo zambiri ndi masitepe, imakhala ndi ndondomeko yovuta, ndipo imapanga zinthu zambiri, zomwe zimachepetsa mphamvu zake zachuma.M'tsogolomu, matekinoloje atsopano ndi njira zikhoza kupangidwa kuti zitheke bwino komanso kuchepetsa mtengo wa kupanga, kutsegula mwayi watsopano wopangira malonda a phenol.
