Phenol ceyriinka

Wacidwaa xarun kiimiko kiimiko ah oo leh codsiyo fara badan oo ka mid ah warshadaha iyo cilmi baarista. Diyaarinta ganacsigeeda waxay ku lug leedahay geedi socod talaabo badan oo ka bilaabmaya oksidation of cyclohexe. Hawshan, Cyclohexhane ayaa loo qoondeeyay taxane iskood ah, oo ay ku jiraan Cyclohexanol iyo Cyclohexanone, oo markaa loo beddelay Phenol. Aynu ku galno faahfaahinta hawshan. 

 

Diyaarinta ganacsiga ee Phenol waxay ku bilaabataa oksidation ee cyclohexe. Fal-celintaan waxaa lagu fuliyaa joogitaanka wakiilka oksidazing, sida hawo hawo ama oksijiin saafi ah, iyo wax soo saarka. Rugtani ee loo adeegsaday fal-galkan ayaa badanaa isku dhafan bir bir ah, sida cobalt, Manganese, iyo bromine. Falcelinta waxaa lagu fuliyaa heerkulka sare iyo cadaadiska, sida caadiga ah u dhexeysa 600 ilaa 900°C iyo 10 illaa 200 oo ah matag, siday u kala horreeyaan.

 

Oksidation of cyclohexine waxay keenaysaa samaynta taxane isbarbardhigaya, oo ay ku jiraan cyclohehexanol iyo cyclohexnone. Dhex-dhexaadintaas ayaa markaa loo beddelaa Phenol talaabo falcelinta xigta. Fal-celintaan waxaa lagu fuliyaa joogitaanka cunsuriyada aashitada, sida sulfuric acid ama hydrochloric acid. Rugaha Acid ayaa dhiirrigelisa fuuq-baxa Cyclohehexanol iyo CyclohexExano, taasoo dhalisay samaynta sahaminta iyo biyaha.

 

Phenol ka dhalanaya ka dib ayaa markaa loo daahiriyaa musiibo iyo farsamooyin kale oo lagu nadiifiyo si looga saaro cilado iyo waxyaabaha kale ee wax soo saarka leh. Habka daahirinta ayaa hubineysa in sheyga ugu dambeeya uu buuxiyo shuruudaha daahirka ee codsiyada kala duwan.

 

Phenol waxaa loo isticmaalaa codsiyo kala duwan, oo ay ku jiraan soosaarka polycarbonyada, bisphenol a (bpa), penolic-ka paceneed, iyo xeryo kale oo kala duwan. Polycarbonates-ka waxaa si weyn loogu isticmaalaa soosaarka weelasha balaastigga ah, muraayadaha indhaha, iyo waxyaabaha kale ee indhaha ah ay sabab u tahay daahfurnaantooda sare iyo iska caabbinta saameynta. BPA waxaa loo isticmaalaa soo saarista dhajinta ephoxy iyo adhesha kale, jaakad, iyo isku-dhafan. Dembiyada phenolic-ka waxaa loo isticmaalaa soo saarista dhagaxa, jaakadaha, iyo composites-ka sababa la xiriira iska caabintooda sare ee kuleylka iyo kiimikooyinka.

 

Gabagabadii, diyaarinta ganacsiga ee Phenol ayaa ku lug leh oksidation ee cyclohexe, oo ay ku xigto beddelka ka dhex dhaca phenol iyo nadiifinta sheyga ugu dambeeya. Phenol ka dhalanaya ee ka dhalanaya codsiyo fara badan, oo ay ku jiraan soosaarka weelasha balaastigga ah, adhessies, jaakad, iyo isku-dhafan.
