PhenolNgaba yeyona nto ibaluleke kakhulu ye-spocial shemickic, esetyenziselwa ukuveliswa kweemveliso ezahlukeneyo zekhemikhali, ezinje ngo-Antioximers, iiarhente zokunyanga, njl njl. Kweli nqaku, siza kwazisa itekhnoloji yokwenziwa kwe-phenol ngokweenkcukacha.
Ukulungiswa kwe-phenol kuqhutywa ngokusabela ngokusabela i-Bezene nge-prophene phambi kwe-catalysts. Inkqubo yokuphendula inokwahlulwa ibe ngamanyathelo amathathu: inyathelo lokuqala kukusabela kwe-bebine kunye neprophenene ukwenza i-cumene; Inyathelo lesibini kukoyiswa kwe-cumene ukwenza i-cumene hydroperoperothide; Kwaye inyathelo lesithathu kukucoceka kwe-cumene hydroperoperoperoxide ukuba yenze i-phenol kunye ne-acetone.
Kwinyathelo lokuqala, i-Bezene kunye ne-propleyne iphendulwa phambi kwe-acid cataight ukwenza i-cumene. Le ndlela yokuphendula yenziwa kwiqondo lokushisa malunga ne-80 ukuya kwi-100 degrees Celsius kunye noxinzelelo malunga ne-10 ukuya kwi-30 kg / cm2. I-Catalyst isetyenzisiwe ihlala i-aluminium chloride okanye i-sulfuric acid. Imveliso yokuphendula yi-cumene, eyahlulwe kumxube wokuphendula ngokuphawula.
Kwinqanaba lesibini, i-cumene i-oxidod inomoya phambi kwe-acid catalyst ukuba yenze i-cumene hydroperoperothide. Le ndlela yokuphendula yenziwa kwiqondo lokushisa malunga nama-70 ukuya kwengama-90 degrees Celsius kunye noxinzelelo malunga ne-1 ukuya kwi-2 kg / cm2. I-Catalyst isetyenzisiwe ihlala i-Sulfuric Acid okanye i-phosphoric acid. Imveliso yokuphendula yi-cumene hydroperoperothide, eyahlulwe kumxube wokuphendula ngokuphamba.
Kwinqanaba lesithathu, i-cumene hydroperoperaxiide icocwe phambi kwe-acid catalytaly ukuba yenze i-phenol kunye ne-acetone. Le ndlela yokuphendula yenziwa kwiqondo lobushushu malunga ne-100 ukuya kwi-130 degrees Celsius kunye noxinzelelo malunga ne-1 ukuya kwi-2 kg / cm2. I-Catalyst isetyenzisiwe ihlala i-Sulfuric Acid okanye i-phosphoric acid. Imveliso yokuphendula ngumxube we-phenol kunye ne-acetone, eyahlulwe kumxube wokuphendula ngokuphamba.
Okokugqibela, ukwahlukana nokuhlanjululwa kwe-phenol kunye ne-acetone kuqhutywa yidiliya. Ukuze ufumane iimveliso ezicocekileyo eziphezulu, uthotho lweekholamu zokudibanisa rhoqo zihlala zisetyenziselwa ukwahlukana nokucocwa. Imveliso yokugqibela yi-phenol, enokusetyenziselwa ukuveliswa kweemveliso ezahlukeneyo zekhemikhali.
Ngamafutshane, ukulungiswa kwe-phenol evela e-Bedzene kunye ne-propleyne malunga nala manyathelo mathathu angentla anokufumana i-phenol ecocekileyo. Nangona kunjalo, le nkqubo kufuneka isebenzise inani elikhulu le-cataid ye-acid, eya kubangela ukuvela okubi kwezixhobo kunye nongcoliseko lwendalo. Ke ngoko, ezinye iindlela zokulungiselela amatsha ziphuhliswa ukutshintsha le nkqubo. Umzekelo, indlela yokulungiselela ye-phenol isebenzisa i-biocatalyts isetyenziswe ngokuthe ngcembe kumzi mveliso.
