I-Propylene oxide ithathwa njengesixhobo esiphakathi ekuvelisweni kwe-polyurethane, i-antifreeze kunye nezinye iikhemikhali zoshishino.imitha yoxinano lwemibhobhoidityaniswe kumgca wemveliso wesakhiwo sokuvelisa i-propylene oxide -- iPropylene Oxide Plant yokulawula ngokuchanekileyo i-chemical reaction, apho i-reactant enye ebalulekileyoi-hydrogen peroxide (H₂O₂)Iphendula kunye nepropylene xa kukho i-catalyst ukuze yenze i-propylene oxide.
Izinga lokusabela, umgangatho wemveliso kunye nokusebenza kakuhle konke oku kunokulungiswa ngeimitha yoxinzelelo lwe-hydrogen peroxidekumanqanaba ahlukeneyo emveliso. Impendulo ephambili ixhomekeke kwimpendulo ye-epoxidation, apho i-propylene isabela ne-hydrogen peroxide (H₂O₂) xa kukho i-catalyst (ngesiqhelo yi-tungstate okanye i-molybdate-based catalyst) ukuze yenze i-propylene oxide (C₃H₆O) kunye namanzi (H₂O).
Amanqaku okulinganisa kwimveliso yePropylene Oxide
Iindawo zokulinganisa ezibalulekileyo ziquka ukungena kwezinto eziluhlaza, isitya sokusabela, isigaba sokwahlulwa kunye nokubuyisela, njl. Ukungena kokutya kwe-hydrogen peroxide yindawo efunekayo ukuqinisekisa iinkcukacha ezifunekayo. Ngokubanzi, i-hydrogen peroxide igcinwa kwimo exineneyo, kwaye kufuneka ixutywe ngaphambi kokuba iqhubeke nokucutshungulwa okanye isabelane nezinye iikhemikhali.
Emva koko yiza kwisitya se-reaction okanye kwi-reactor. Eli lelinye inqanaba lokulinganisa leumlinganiselo woxinzelelo lwe-hydrogen peroxideukuze impendulo iqhubeke njengoko kulindelekile. imitha yoxinano lwenkqubo emgceniokanye esinye isenzi-luvo siyakwazi ukufakwa kwindawo yokukhupha i-reactor ukuze sijonge uxinano lwe-hydrogen peroxide ngexesha langempela njengoko isabela kwi-propylene.imitha yoxinano kwi-intanethiivumela uhlengahlengiso oluguquguqukayo lwe-hydrogen peroxide olunokwenzeka ukuze ihlale ijongiwe. Ukuba uxinzelelo lwehla ngokukhawuleza okanye impendulo ayiqhubeki njengoko bekulindelwe, kuyimfuneko ukulungisa ukuhamba kwe-hydrogen peroxide kwi-reactor.
Emva kokusabela kubandakanya ukwahlulwa nokucocwa kwe-propylene oxide kunye neemveliso eziphuma kuyo, ezinje ngamanzi kunye ne-hydrogen peroxide engaphendulwanga. Umzekelo, i-hydrogen peroxide ekumgangatho ophezulu ibeka umngcipheko ekuzinzeni kwendalo kunye nokhuseleko lwabantu. Ukulinganiswa koxinzelelo olufanelekileyo kwenza ukuba ubungakanani kunye nokucutshungulwa okuzinzileyo kube nokwenzeka ukuze kuhambelane nemithetho nemigaqo.
Iinkqubo zokulinganisa ezikrelekrele kwiindawo ezibalulekileyo kwinkqubo zinceda kakhulu ekwenzeni ngcono imveliso. Ukusebenzisa ubuchwepheshe obuphambili obufanaii-densitometers ezikwi-intanethi, ii-spectrophotometers, kunye neendlela ze-titration zivumela ukujonga ngexesha langempela, ukulinganisa okuchanekileyo koxinzelelo, kunye nolawulo olungcono lwenkqubo, ekugqibeleni okukhokelela kwisivuno esiphezulu kunye nemisebenzi ekhuselekileyo.
Nceda unxibelelaneILonnmeteriinjineli ukuze ufumane iingcebiso ezithe vetshe malunganomgca imitha yoxinzelelo lwe-hydrogen peroxide ukuze ubone ukuba ingaba ingasetyenziswa na kumgca wakho wemveliso okanye kwizityalo. Cela ikowuteshini yasimahla ngoku kwaye ufumane ixabiso lemitha yoxinano.
