Phenol Raw Star

Phenolndi mankhwala ofananira ndi ntchito zosiyanasiyana pamakampani ndi kufufuza. Kukonzekera kwake kumaphatikizapo njira zingapo zomwe zimayamba ndi ma okosijeni a cyclohexane. Munjira iyi, cyclohexane ili oxidized mumitundu ingapo, kuphatikiza cyclohexhexnol ndi cyclohexnone, yomwe imasinthidwa kukhala phenol. Tiyeni tisanthule mwatsatanetsatane njirayi. 

 

Kukonzekera kwa phenol kumayamba ndi makutidwe a cyclohexane. Izi zikuchitika pamaso pa wothandizira wa oxiding, monga mpweya kapena mpweya wabwino, komanso chothandizira. Chothandizira chomwe chimagwiritsidwa ntchito mu izi nthawi zambiri chimasakaniza zitsulo zosintha, monga cobalt, manganese, ndi bromine. Zomwe zimachitika zimachitika pamatenthedwe okwezeka komanso zovuta, kuyambira 600 mpaka 900°C ndi 10 mpaka 200 mlengalenga, motsatana.

 

Makutidwenation a cyclohexane amapanga mapangidwe angapo apakatikati, kuphatikiza cyclohexhexnol ndi cyclohexnone. Pakatikati pamakhala phenol motsatira zomwe zimachitika pambuyo pake. Izi zimachitika pamaso pa chothandizira cha acid, monga sulfuric acid kapena hydrochloric acid. Acid acid imalimbikitsa madzi a cyclohexhexanol ndi cyclohexnone, zomwe zimapangitsa ma phenol ndi madzi.

 

Zotsatira zake zimatsukidwa ndi distillation ndi njira zina zoyeretsera kuti muchotse zodetsa ndi zina. Njira yoyeretsa imatsimikizira kuti chinthu chomaliza chimakumana ndi zoyera zamapulogalamu osiyanasiyana.

 

Phenol amagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo kupanga kwa polycarbonates, bisphenol a (bpa), ma resunolic, ndi zinthu zina zingapo. Ma Polycarbona amagwiritsidwa ntchito kwambiri popanga ma pulasitiki, magalasi, ndi zida zina zam'maso chifukwa cha kuwonekera kwawo kwakukulu komanso kukana. BPA imagwiritsidwa ntchito popanga epoxy unin ndi zomata zina, zokutira, ndi gulu. Matunga a Phenolic amagwiritsidwa ntchito popanga zomatira, zokutira, ndi mitundu chifukwa cha kukana kwawo kwambiri kutentha ndi mankhwala.

 

Pomaliza, kukonzekera kwa phenol kumaphatikizapo makutidwe a cyclohexne, omwe amatsatiridwa ndi kutembenuka kwapakatikati mu phenol ndi kuyeretsa kwa chinthu chomaliza. Phenol yomwe imagwiritsidwa ntchito imagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo kupanga pulasitiki, zomata, zokutira, ndi mitundu.
