I-Phenolibaluleke kakhulu i-organic chemical material eluhlaza, enohlu olubanzi lokusetshenziswa embonini yamakhemikhali nakweminye imikhakha.Kulesi sihloko, sizohlaziya futhi sixoxe ngemikhiqizo emikhulu ye-phenol.

Phenol impahla eluhlaza 

 

sidinga ukwazi ukuthi yini i-phenol.I-Phenol iyinhlanganisela ye-hydrocarbon enephunga elimnandi ene-molecular formula C6H6O.Kuyikristalu engenambala noma emhlophe eqinile enephunga elikhethekile.I-Phenol isetshenziswa kakhulu njengempahla eluhlaza ekukhiqizeni imikhiqizo ehlukahlukene yamakhemikhali, njenge-bisphenol A, i-phenolic resin, njll. I-Bisphenol A ingenye yemikhiqizo ebaluleke kakhulu ye-phenol, esetshenziswa kakhulu ekukhiqizeni i-epoxy resin, ipulasitiki. , i-fiber, ifilimu, njll. Ngaphezu kwalokho, i-phenol iphinde isetshenziswe njengento eluhlaza ekukhiqizeni imithi, izibulala-zinambuzane, odayi, ama-surfactants neminye imikhiqizo yamakhemikhali.

 

Ukuze siqonde imikhiqizo emikhulu ye-phenol, kufanele siqale sihlaziye inqubo yayo yokukhiqiza.Inqubo yokukhiqiza i-phenol ngokuvamile ihlukaniswe ngezinyathelo ezimbili: isinyathelo sokuqala ukusebenzisa itiyela yamalahle njengempahla eluhlaza ukukhiqiza i-benzene ngenqubo ye-carbonization kanye ne-distillation;Isinyathelo sesibili ukusebenzisa i-benzene njengempahla eluhlaza ukukhiqiza i-phenol ngenqubo ye-oxidation, i-hydroxylation kanye ne-distillation.Kule nqubo, i-benzene i-oxidized ukuze yakhe i-phenolic acid, bese i-phenolic acid iphinde ifakwe i-oxid ukuze yakhe i-phenol.Ngaphezu kwalokho, kunezinye izindlela zokukhiqiza i-phenol, njengokuguqulwa kwe-catalytic ye-petroleum noma i-coal-tar gasification.

 

Ngemva kokuqonda inqubo yokukhiqiza ye-phenol, singaqhubeka sihlaziya imikhiqizo yayo emikhulu.Njengamanje, umkhiqizo obaluleke kakhulu we-phenol yi-bisphenol A. Njengoba kushiwo ngenhla, i-bisphenol A isetshenziswa kabanzi ekukhiqizeni i-epoxy resin, ipulasitiki, i-fiber, ifilimu neminye imikhiqizo.Ngaphandle kwe-bisphenol A, kukhona neminye imikhiqizo ebalulekile ye-phenol, njenge-diphenyl ether, i-nylon 66 usawoti, njll. I-Diphenyl ether isetshenziswa ikakhulukazi njengento yepulasitiki engashi futhi esebenza kakhulu kanye nezithasiselo embonini ye-electronics;Inayiloni 66 usawoti ungasetshenziswa njengefayibha ephezulu amandla kanye nepulasitiki yobunjiniyela emikhakheni ehlukahlukene efana nemishini, izimoto kanye ne-aerospace.

 

Sengiphetha, umkhiqizo omkhulu we-phenol yi-bisphenol A, esetshenziswa kabanzi ekukhiqizeni i-epoxy resin, ipulasitiki, i-fiber, ifilimu neminye imikhiqizo.Ngaphezu kwe-bisphenol A, kukhona neminye imikhiqizo ebalulekile ye-phenol, njenge-diphenyl ether kanye ne-nylon 66 kasawoti.Ukuze kuhlangatshezwane nezidingo zemikhakha ehlukene yesicelo, kuyadingeka ukuqhubeka nokuthuthukisa inqubo yokukhiqiza kanye nekhwalithi yomkhiqizo we-phenol nemikhiqizo yayo emikhulu.
