Phenolke motsoako oa lik'hemik'hale o nang le mefuta e mengata e fapaneng ea ts'ebeliso indastering le lipatlisisong.Tokisetso ea eona ea khoebo e kenyelletsa ts'ebetso ea mehato e mengata e qalang ka oxidation ea cyclohexane.Ts'ebetsong ena, cyclohexane e oxidized hore e be letoto la li-intermediate, ho akarelletsa le cyclohexanol le cyclohexanone, tse ntan'o fetoloa phenol.A re ke re hlahlobeng lintlha tsa mokhoa ona.
Tokisetso ea khoebo ea phenol e qala ka oxidation ea cyclohexane.Karabelo ena e etsoa ka pel'a moemeli oa oxidizing, joalo ka moea kapa oksijene e hloekileng, le mokelikeli.Ntho e sebelisoang karabelong ena hangata ke motsoako oa litšepe tsa phetoho, joalo ka cobalt, manganese le bromine.Karabelo e etsoa ka mocheso o phahameng le likhatello, hangata ho tloha ho 600 ho isa ho 900.°C le 10 ho isa ho 200 atmosphere, ka ho latellana.
Oxidation ea cyclohexane e fella ka ho thehoa ha letoto la li-intermediate, ho akarelletsa le cyclohexanol le cyclohexanone.Li-intermediate tsena li fetoloa phenol mohatong o latelang oa karabelo.Boitšoaro bona bo etsoa ka pel'a motsoako oa acid, joalo ka sulfuric acid kapa hydrochloric acid.Sehlahisoa sa acid se khothalletsa ho felloa ke metsi 'meleng oa cyclohexanol le cyclohexanone, e leng se etsang hore ho thehoe phenol le metsi.
Phenol e hlahisoang ebe e hloekisoa ka distillation le mekhoa e meng ea ho hloekisa ho tlosa litšila le lihlahisoa tse ling.Mokhoa oa tlhoekiso o netefatsa hore sehlahisoa sa ho qetela se kopana le litlhoko tsa bohloeki bakeng sa likopo tse fapaneng.
Phenol e sebelisoa lits'ebetsong tse fapaneng, ho kenyelletsa tlhahiso ea polycarbonates, Bisphenol A (BPA), li-resin tsa phenolic, le metsoako e meng e fapaneng.Li-polycarbonates li sebelisoa haholo ha ho etsoa lijana tsa polasetiki, lilense le lisebelisoa tse ling tsa optical ka lebaka la pepenene ea tsona e phahameng le ho hanyetsa tšusumetso.BPA e sebelisoa ha ho etsoa li-resin tsa epoxy le likhomaretsi tse ling, likoahelo le metsoako.Li-resin tsa phenolic li sebelisoa ha ho etsoa li-adhesives, coatings le composite ka lebaka la ho hanyetsa mocheso le lik'hemik'hale tse phahameng.
Qetellong, tokisetso ea khoebo ea phenol e kenyelletsa oxidation ea cyclohexane, e lateloa ke phetoho ea li-intermediates ho phenol le tlhoekiso ea sehlahisoa sa ho qetela.Phenol e hlahisoang e sebelisoa mefuteng e mengata ea lisebelisoa, ho kenyelletsa le tlhahiso ea lijana tsa polasetiki, li-adhesives, coatings le composite.
