Phenolke ntho ea bohlokoa haholo ea lik'hemik'hale tse tala, tse sebelisoang haholo ha ho etsoa lihlahisoa tse sa tšoaneng tsa lik'hemik'hale, tse kang li-plasticizers, li-antioxidants, mahlahana a folisang, joalo-joalo. Ka hona, ke habohlokoa haholo ho tseba theknoloji ea tlhahiso ea phenol. Sehloohong sena, re tla hlahisa theknoloji ea tlhahiso ea phenol ka botlalo.

Ho lokisoa ha phenol hangata ho etsoa ka ho arabela benzene ka propylene ka pel'a li-catalysts. Ts'ebetso ea karabelo e ka aroloa ka mehato e meraro: mohato oa pele ke karabelo ea benzene le propylene ho theha cumene; mohato oa bobeli ke oxidation ea cumene ho theha cumene hydroperoxide; 'me mohato oa boraro ke ho petsoha ha cumene hydroperoxide ho etsa phenol le acetone.

Mothating oa pele, benzene le propylene li sebetsa ka pel'a motsoako oa asiti ho theha cumene. Boitšoaro bona bo etsoa ka mocheso oa likhato tse 80 ho isa ho tse 100 tsa Celsius le khatello e ka bang 10 ho isa ho 30 kg / cm2. Ntho e sebelisoang hangata ke aluminium chloride kapa sulfuric acid. Sehlahisoa sa karabelo ke cumene, e arohaneng le motsoako oa karabelo ka distillation.

Mothating oa bobeli, cumene e entsoe ka oxidized ka moea ka pel'a motsoako oa asiti ho etsa cumene hydroperoxide. Boitšoaro bona bo etsoa ka mocheso oa likhato tse 70 ho isa ho tse 90 tsa Celsius le khatello e ka bang 1 ho isa ho 2 kg/cm2. Ntho e sebelisoang hangata ke sulfuric acid kapa phosphoric acid. Sehlahisoa sa karabelo ke cumene hydroperoxide, e arohaneng le motsoako oa karabelo ka distillation.

Mothating oa boraro, cumene hydroperoxide e petsoha ka pel'a motsoako oa asiti ho etsa phenol le acetone. Boitšoaro bona bo etsoa ka mocheso oa likhato tse 100 ho isa ho tse 130 tsa Celsius le khatello ea hoo e ka bang 1 ho 2 kg / cm2. Ntho e sebelisoang hangata ke sulfuric acid kapa phosphoric acid. Sehlahisoa sa karabelo ke motsoako oa phenol le acetone, e arohaneng le motsoako oa karabelo ka distillation.

Qetellong, karohano le tlhoekiso ea phenol le acetone li etsoa ka distillation. E le ho fumana lihlahisoa tse phahameng tsa bohloeki, letoto la litšiea tsa distillation li atisa ho sebelisoa bakeng sa ho arohana le ho hloekisa. Sehlahisoa sa ho qetela ke phenol, e ka sebelisetsoang ho hlahisa lihlahisoa tse sa tšoaneng tsa lik'hemik'hale.

Ka kakaretso, ho lokisoa ha phenol ho tsoa ho benzene le propylene ka mehato e meraro e kaholimo ho ka fumana phenol ea bohloeki bo phahameng. Leha ho le joalo, ts'ebetso ena e hloka ho sebelisa palo e kholo ea li-catalyst tsa acid, tse tla baka ho bola ho hoholo ha lisebelisoa le tšilafalo ea tikoloho. Ka hona, mekhoa e meng e mecha ea ho lokisetsa e hlahisoa ho nkela mokhoa ona sebaka. Ka mohlala, mokhoa oa ho lokisetsa phenol o sebelisang li-biocatalyst o 'nile oa sebelisoa butle-butle indastering.
