I-Phenol Suble

Phenolyinxalenye yekhemikhali yekhemikhali eguquguqukayo kunye noluhlu olubanzi lwezicelo kumzi mveliso nophando. Ukulungiselela kwezorhwebo kubandakanya inkqubo yamanyathelo amaninzi eqala nge-oxidation ye-cyclohexane. Kule nkqubo, i-cycycycloheXane i-oxidod ibe uthotho lwabantu abaphakathi, kuquka ne-cyclohexungXanol kunye ne-cyclohexunkoanone, eziguqulwa zibe yi-phenol. Masiphathe kwiinkcukacha zale nkqubo. 

 

Ukulungiswa kwentengiso kwe-phenol kuqala nge-oxidation ye-cyclohexane. Le ndlela yokuphendula yenziwa phambi kwearhente ye-oxidiching, efana nomoya okanye ioksijini ecocekileyo, kunye ne-catalyst. Eyona nto isetyenziswayo kule mpendulo ihlala ingumxube wezinyithi zotshintsho, ezinje ngoCobabat, Manganese, naseBromino. Indlela yokuphendula yenziwa ngamaqondo obushushu aphakamileyo kunye noxinzelelo, oqhele ukusukela kwi-600 ukuya kwi-900°C kunye ne-10 ukuya kwi-200 ye-200 moya, ngokwahlukeneyo.

 

I-oxidation ye-cycloheane iphumela ekuqulunqweni kothotho lwabantu abaphakathi, kubandakanya i-cyclohexungXanol kunye ne-cyclohexXanone. Aba bangelweyo baguqulwa babe kwi-phenol kwinyathelo lokuphendula elilandelayo. Le ndlela yokuphendula yenziwa phambi kwe-acid catalyst, efana ne-sulfuric acid okanye i-hydrochloric acid. I-Acid Catalyst ikhuthaza ukupheliswa kwempahla emzimbeni we-cycloheXanol kunye ne-cyclohexXanone, ekhokelela ekuqulunqweni kwe-phenol namanzi.

 

I-phenous ye-phenol ihlanjululwe yidiliki kunye nezinye iindlela zokucoca ukususa ukungcola kunye nezinye iimveliso. Inkqubo yokucoca iqinisekisa ukuba imveliso yokugqibela ihlangabezana neemfuno zokucoceka kwezicelo ezahlukeneyo.

 

I-phenol isetyenziswa kwizicelo ezahlukeneyo, kubandakanya ukuveliswa kwe-polycarbonates, i-bisphenol a (bPA), i-fehefolins iphindaphindiweyo, kunye nezinye iikhomputer ezahlukeneyo. I-polycarboonates isetyenziswa ngokubanzi ekuvelisweni kwezikhongozeli zeplastiki, iilensi, kunye nezinye izinto ezingalindelekanga ngenxa yokungafihlisi kwabo kunye nokuxhathisa kwimpembelelo. I-BPA isetyenziswa ekuvelisweni kwe-Epoxy Reward kunye nabanye abanamaphetshana, iingubo kunye neziqu. I-fedins isetyenziswa ekuvelisweni kwee-adheshees, iingubo, kunye nezihloko ngenxa yokuxhathisa kwabo ubushushu kunye neekhemikhali.

 

Ukuqukumbela, ukulungiswa kwentengiso zentengiso kubandakanya i-oxidation ye-cyclohexane, kulandelwe kukuguqulwa kwamaphepha aphakathi kwi-phenol nokuhlanjululwa kwemveliso yokugqibela. I-phenous ye-phemol isetyenziswa kuluhlu olubanzi lwezicelo, kubandakanya ukuveliswa kwezikhongozeli zeplastiki, amayeza, iingubo, kunye neziqu.
