Phenolndizofunika kwambiri zopangira organic, zomwe zimagwiritsidwa ntchito kwambiri popanga mankhwala osiyanasiyana, monga pulasitiki, mphira, mankhwala, mankhwala ophera tizilombo, ndi zina zotero.
Zopangira zopangira phenol makamaka zimakhala benzene, methanol ndi sulfuric acid. Benzene ndi chinthu chofunika kwambiri cha organic, chomwe chingagwiritsidwe ntchito popanga mitundu yambiri ya mankhwala, monga phenol, aniline, acetophenone ndi zina zotero. Methanol ndi yofunika organic yaiwisi, amene angagwiritsidwe ntchito kupanga zosiyanasiyana mankhwala ndi mpweya munali magulu zinchito. Sulfuric acid ndi asidi wofunikira, womwe umagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala ndi mafakitale ena.
Njira yopangira phenol kuchokera ku benzene, methanol ndi sulfuric acid ndizovuta kwambiri. Choyamba, benzene ndi methanol amachitidwa pansi pa chothandizira kupanga cumene. Kenako, cumene imapangidwa ndi okosijeni pamaso pa mpweya kupanga cumene hydroperoxide. Pomaliza, cumene hydroperoxide imayendetsedwa ndi diluted sulfuric acid kupanga phenol ndi acetone.
Popanga phenol, kusankha chothandizira ndikofunikira kwambiri. Zothandizira zomwe zimagwiritsidwa ntchito kwambiri ndi aluminium chloride, sulfuric acid ndi phosphoric acid. Komanso, zinthu ndondomeko monga kutentha, kuthamanga ndi ndende amakhudzanso zokolola ndi khalidwe la mankhwala.
Nthawi zambiri, zopangira zopangira phenol zimakhala zovuta, ndipo njira zake zimakhala zovuta. Pofuna kupeza apamwamba ndi apamwamba zokolola, m`pofunika mosamalitsa kulamulira zopangira khalidwe ndi ndondomeko zinthu. Kuphatikiza apo, m'pofunikanso kuganizira zachitetezo cha chilengedwe ndi chitetezo pakupanga. Choncho, pogwiritsira ntchito phenol ngati zopangira kupanga mankhwala osiyanasiyana, tiyenera kumvetsera mbali izi kuti titsimikizire kuti titha kupeza zinthu zapamwamba komanso zokolola zambiri pamene tikuteteza chilengedwe ndi chitetezo.
