Phenol ke setho se bonolo ka ho fetisisa sa sehlopha sa metsoako ea organic e nang le sehlopha sa hydroxyl se hoketsoeng lesale la benzene kapa tsamaiso e thata haholoanyane ea monko o monate.
E boetse e tsejoa e le carbolic acid kapa monohydroxybenzene, phenol ke ntho e se nang 'mala ho isa ho e tšoeu ea kristale e monko o monate, e nang le sebopeho sa C6H5OH, se fumanoeng ho tsoa ho distillation ea sekontiri sa mashala hape e le sehlahisoa sa lionto tsa coke.
Phenol e na le thepa e pharalletseng ea biocidal, 'me litharollo tsa metsi tse hlapollang haesale li sebelisoa joalo ka sebolaya-mafu. Libakeng tse phahameng, e baka ho chesoa ha letlalo ho matla; ke chefo e mabifi ea tsamaiso. Ke lisebelisoa tsa bohlokoa tsa lik'hemik'hale bakeng sa tlhahiso ea polasetiki, dae, meriana, li-sytans le lihlahisoa tse ling.
Phenol e qhibiliha hoo e ka bang 43°C mme e bela ka 183°C. Limaraka tse hloekileng li na le ntlha ea ho qhibiliha ea 39°C, 39.5°C, le 40°C. Limaraka tsa tekheniki li na le 82% -84% le 90% -92% phenol. Sebaka sa crystallization se fanoa e le 40.41 ° C. Matla a khoheli a khethehileng ke 1.066. E qhibiliha ka har'a metsoako e mengata ea tlhaho. Ka ho qhibilihisa likristale le ho eketsa metsi, phenol ea metsi e hlahisoa, e lulang e le metsi ka mocheso o tloaelehileng. Phenol e na le thepa e sa tloaelehang ea ho kenella ka har'a lisele tse phelang le ho etsa sebolaya-mafu sa bohlokoa. E boetse e sebelisoa indastering ho seha oli le metsoako le litsing tsa letlalo.
