Ipropylene oxide ithathwa njengendawo ephakathi kwimveliso ye-polyurethane, i-antifreeze kunye nezinye iikhemikhali zamashishini. Aimitha yoxinano lombhobhoidityaniswe kumgca wemveliso yepropylene oxide yokuvelisa iPropylene Oxide Plant yolawulo oluchanekileyo lokusabela kweekhemikhali, apho ireactant ibalulekile.ihydrogen peroxide (H₂O₂)idibana nepropylene kubukho be-catalyst ukwenza ipropylene oxide.
Ireyithi yokusabela, umgangatho wemveliso kunye nocikizeko ngokubanzi zonke zinokuhlengahlengiswa ngokusebenzisa aimitha yoxinaniso lwehydrogen peroxidekumanqanaba ahlukeneyo emveliso. Eyona ndlela yokusabela iphumle kwi-epoxidation reaction, apho ipropylene isabela ngehydrogen peroxide (H₂O₂) phambi kwe-catalyst (idla ngokuba yi-tungstate okanye i-molybdate-based catalyst) ukwenza ipropylene oxide (C₃H₆O) kunye namanzi (H₂O).
Amanqaku okulinganisa kwiMveliso yePropylene Oxide
Amanqaku okulinganisa abalulekileyo abandakanya ukungena kwempahla ekrwada, isitya sokusabela, ukwahlula kunye nesigaba sokubuyisela, njl. njl Ngokuqhelekileyo, i-hydrogen peroxide igcinwa kwimo egxininisiweyo, kwaye kufuneka ihlanjululwe ngaphambi kokuba iqhutywe okanye isabelane neminye imichiza.
Emva koko uze kwisitya sokuphendula okanye i-reactor. Le yenye indawo yokulinganisaumlinganiselo woxinaniso lwehydrogen peroxideukuze impendulo iqhubele phambili njengoko bekulindelekile. An imitha yoxinaniso lwenkqubo engaphakathiokanye enye inzwa iyakwazi ukufakwa kwi-outlet ye-reactor ukubeka iliso ngexesha lokwenene loxinzelelo lwe-hydrogen peroxide njengoko isabela ngepropylene. Abakrelekreleimitha yoxinaniso kwi-intanethiyenza uhlengahlengiso oluguquguqukayo lwehydrogen peroxide lunokwenzeka ukulungiselela uqwalaselo oluqhubekayo. Kwimeko apho ugxininiso lwehla ngokukhawuleza kakhulu okanye impendulo ayiqhubeki njengoko kulindelekile, kuyafuneka ukulungisa ukuhamba kwehydrogen peroxide kwireactor.
I-post-reaction ibandakanya ukuhlukana kunye nokucocwa kwepropylene oxide kunye neemveliso, ezifana namanzi kunye ne-hydrogen peroxide engaphendulwanga. Umzekelo, umgangatho ophezulu we-hydrogen peroxide ubeka imingcipheko kulondolozo lwendalo kunye nokhuseleko lomntu. Umlinganiselo wokuxinana ofanelekileyo wenza ukubalwa kwamanani kunye nokuqhubekeka okuzinzileyo kunokwenzeka ukuthobela imithetho nemimiselo.
Iinkqubo zokulinganisa ezikrelekrele kumanqaku abalulekileyo kwinkqubo inceda kakhulu ekuphuculeni imveliso. Ukusebenzisa itekhnoloji ephezulu efanaIidensitometers ze-intanethi, i-spectrophotometers, kunye neendlela ze-titration zivumela ukubeka iliso ngexesha langempela, imilinganiselo yogxininiso echanekileyo, kunye nokulawulwa kwenkqubo engcono, ekugqibeleni kukhokelela kwisivuno esiphezulu kunye nokusebenza okukhuselekileyo.
Nceda uqhagamshelaneLonnmeteriinjineli zothethwano ngakumbi malunganomgca imitha yoxinaniso lwehydrogen peroxide ukufumanisa ukuba ingasetyenziswa kumgca wakho wemveliso okanye kwizityalo. Cela isaphulelo sasimahla ngoku kwaye ufumane ixabiso lemitha yoxinaniso.
