I-Propylene oxide ithathwa njengesikhungo esiphakathi ekukhiqizweni kwe-polyurethane, i-antifreeze kanye namanye amakhemikhali ezimboni.imitha yobuningi bepayipiihlanganiswe nomugqa wokukhiqiza wesikhungo sokukhiqiza i-propylene oxide -- Isitshalo se-Propylene Oxide ukuze kulawulwe ngokunembile ukusabela kwamakhemikhali, lapho i-reactant eyodwa ebalulekilei-hydrogen peroxide (H₂O₂)iphendula ne-propylene lapho kukhona i-catalyst ukuze yakhe i-propylene oxide.
Izinga lokusabela, ikhwalithi yomkhiqizo kanye nokusebenza kahle konke kungalungiswa nge-imitha yokuhlushwa kwe-hydrogen peroxideezigabeni ezahlukene zokukhiqizwa. Ukusabela okuyinhloko kuncike ekusabeleni kwe-epoxidation, lapho i-propylene isabela khona ne-hydrogen peroxide (H₂O₂) lapho kukhona i-catalyst (ngokuvamile i-tungstate noma i-catalyst esekelwe ku-molybdate) ukuze yakhe i-propylene oxide (C₃H₆O) kanye namanzi (H₂O).
Amaphuzu Okulinganisa Ekukhiqizweni kwe-Propylene Oxide
Amaphuzu okulinganisa abalulekile afaka phakathi ukungena kwezinto zokusetshenziswa, isitsha sokusabela, isigaba sokuhlukaniswa kanye nesigaba sokululama, njll. Ukungena kokudla kwe-hydrogen peroxide kuyiphuzu elidingekayo ukuqinisekisa imininingwane edingekayo. Ngokuvamile, i-hydrogen peroxide igcinwa isesimweni esiqinile, futhi idinga ukuxutshwa ngaphambi kokucutshungulwa okwengeziwe noma ukusabela namanye amakhemikhali.
Bese ufika esitsheni sokusabela noma ku-reactor. Lena enye indawo yokulinganisaukulinganiswa kokuhlushwa kwe-hydrogen peroxideukuze ukusabela kuqhubeke njengoba kulindelekile. imitha yobuningi benqubo eqondilenoma enye inzwa iyakwazi ukufakwa endaweni yokukhipha i-reactor ukuze iqaphe ukuhlushwa kwe-hydrogen peroxide ngesikhathi sangempela njengoba isabela ne-propylene.imitha yobuningi ku-inthanethikwenza kube lula ukulungisa okuguquguqukayo kwe-hydrogen peroxide ukuze kuqashwe njalo. Uma kwenzeka ukuthi ukuhlushwa kwehle ngokushesha kakhulu noma ukusabela kungaqhubeki njengoba kulindelekile, kuyadingeka ukulungisa ukugeleza kwe-hydrogen peroxide ku-reactor.
Ngemva kokusabela kuhilela ukuhlukaniswa nokuhlanzwa kwe-propylene oxide kanye nemikhiqizo ephumayo, njengamanzi kanye ne-hydrogen peroxide engaphendulwanga. Isibonelo, i-hydrogen peroxide esezingeni eliphezulu ibeka engcupheni ekusimeni kwemvelo kanye nokuphepha kwabantu. Ukulinganisa ukuhlushwa okufanele kwenza ukulinganisa kanye nokucubungula okusimeme kwenzeke ukuze kuhambisane nemithetho nemigomo.
Izinhlelo zokulinganisa ezihlakaniphile ezindaweni ezibalulekile zenqubo zisiza kakhulu ekwenzeni ngcono ukukhiqiza. Ukusebenzisa ubuchwepheshe obuthuthukisiwe obufanaama-densitometer aku-inthanethi, ama-spectrophotometer, kanye nezindlela ze-titration zivumela ukuqapha ngesikhathi sangempela, ukulinganisa okunembile kokuhlushwa, kanye nokulawula izinqubo okungcono, ekugcineni okuholela ekuvuneni okuphezulu kanye nokusebenza okuphephile.
Sicela uxhumaneI-Lonnmeteronjiniyela ukuze bathole ukubonisana okwengeziwe mayelanaemugqeni imitha yokuhlushwa kwe-hydrogen peroxide ukuthola ukuthi ingasetshenziswa yini emugqeni wakho wokukhiqiza noma ezitshalweni. Cela ikhotheshini yamahhala manje bese uthola intengo yemitha yobuningi.
