I-propylene oxideisetshenziswa kabanzi ngamakhemikhali aluhlaza, asetshenziswa kakhulu ekukhiqizeni i-polyether polyols, i-polyurethanes, ama-surfactants, njll. I-propylene oxide esetshenziselwa ukuhlanganiswa kwale mikhiqizo ngokuvamile itholakala nge-oxidation ye-propylene ene-catalysts ehlukahlukene. Ngakho-ke, impendulo yombuzo wokuthi i-propylene oxide iyinhlangano yebo yebo.

Ithangi lokugcina le-epoxy propane

 

Okokuqala, ake sibheke umthombo we-propylene oxide. I-Propylene oxide iwuhlobo lwamakhemikhali abalulekile asetshenziswayo atholakala ku-propylene. I-Propylene iwuhlobo lwe-olefin etholwe ngokuqhekeka kukaphethiloli, futhi isakhiwo sayo samangqamuzana sakhiwe nge-carbon ne-hydrogen kuphela. Ngakho-ke, i-propylene oxide eyenziwe nge-propylene nayo iwuhlobo lwenhlanganisela yezinto eziphilayo ezakhiwe kuphela i-carbon ne-hydrogen.

 

Okwesibili, singakwazi futhi ukuhlaziya inqubo yokwenziwa ye-propylene oxide. Inqubo yokwenziwa ye-propylene oxide ngokuvamile isebenzisa ama-catalysts ahlukahlukene ukwenza ukusabela kwe-oxidation ye-propylene ngaphansi kwezinga lokushisa eliphezulu nezimo zengcindezi ephezulu. Phakathi kwabo, i-catalyst evame ukusetshenziswa kakhulu isiliva. Enkambweni yokusabela kwe-oxidation, i-propylene nomoya-mpilo emoyeni kukhishwa isiliva ukukhiqiza i-propylene oxide. Ngaphezu kwalokho, amanye ama-catalysts afana ne-titanium dioxide ne-tungsten oxide nawo avame ukusetshenziselwa ukuhlanganiswa kwe-propylene oxide.

 

Ekugcineni, singaphinda sihlaziye ukusetshenziswa kwe-propylene oxide. I-Propylene oxide isetshenziswa kakhulu ekukhiqizeni ama-polyether polyols, i-polyurethanes, ama-surfactants, njll. Le mikhiqizo isetshenziswa kakhulu ekuphileni kwansuku zonke, njenge-polyurethane foam yokwahlukanisa nokumelana nokushaqeka, ama-polyether polyols ama-epoxy resins, ama-surfactants okuhlanza nokugeza. Ngakho-ke, ukusetshenziswa kwe-propylene oxide kubanzi kakhulu.

 

Ngokusekelwe ekuhlaziyeni okungenhla, singafinyelela isiphetho sokuthi i-propylene oxide iwumkhiqizo wokwenziwa osuselwe ku-propylene ngokusabela kwe-oxidation ngama-catalysts ahlukahlukene. Umthombo wayo, inqubo yokwenziwa kanye nokusetshenziswa konke kuhlobene eduze nempilo yomuntu nemisebenzi yokukhiqiza.
