Kushandurwa kwepropylene kuita propylene oxide inzira yakaoma inoda kunyatsonzwisiswa kwemakemikari ekuita maitiro anobatanidzwa. Ichi chinyorwa chinotarisa munzira dzakasiyana-siyana uye maitiro ekuita anodiwa pakugadzirwa kwepropylene oxide kubva kupropylene.

Nzira yakajairika yekugadzirwa kwepropylene oxide ndeye kuburikidza neoxidation yepropylene ine molecular oxygen muhupo hwekugadzirisa. Maitiro ekuita anosanganisira kuumbwa kweperoxy radicals, iyo inobva yaita nepropylene kuburitsa propylene oxide. Iyo catalyst inoita basa rakakosha mukuita uku, sezvo ichidzikisa iyo activation simba inodiwa pakugadzira peroxy radicals, nekudaro ichiwedzera chiyero chekuita.

Imwe yeanonyanya kushandiswa macatalysts ekuita uku iSilver oxide, inotakurwa pachinhu chekutsigira senge alpha-alumina. Zvinhu zvinotsigira zvinopa nzvimbo yakakwirira yepamusoro yezvinokonzera, kuve nechokwadi chekubatana kwakanaka pakati pezvinogadzirisa uye zvinokonzera. Kushandiswa kwesilver oxide catalysts kwakawanikwa kuchikonzera goho repamusoro repropylene oxide.

Iyo oxidation yepropylene uchishandisa peroxide process ndiyo imwe nzira inogona kushandiswa pakugadzira propylene oxide. Muchiitiko ichi, propylene inobatwa ne organic peroxide muhupo hwekugadzirisa. Iyo peroxide inopindirana nepropylene kuumba yepakati mahara radical, iyo inobva yaora kuti ibudise propylene oxide uye doro. Iyi nzira ine mukana wekupa yakakwira selectivity yepropylene oxide kana ichienzaniswa neiyo oxidation process.

Sarudzo yemamiriro ekuita kwakakoshawo pakuona goho uye kuchena kwechigadzirwa chepropylene oxide. Iyo tembiricha, kudzvanywa, nguva yekugara, uye moleshi reshiyo yezvinoita mamwe emamwe maparamita akakosha anoda kugadziridzwa. Izvo zvakaonekwa kuti kuwedzera tembiricha uye nguva yekugara zvinowanzokonzera kuwedzera kwegoho repropylene oxide. Zvisinei, kutonhora kwepamusoro kunogonawo kutungamirira pakuumbwa kwezvigadzirwa, kuderedza kuchena kwechigadzirwa chinodiwa. Nokudaro, kuenzana pakati pezvibereko zvakakwirira uye kuchena kwakanyanya kunofanira kurohwa.

Mukupedzisa, kuumbwa kwepropylene oxide kubva kupropylene kunogona kuwanikwa kuburikidza nenzira dzakasiyana-siyana, kusanganisira oxidation ne molecular oxygen kana peroxide maitiro. Sarudzo yezvinokonzeresa uye maitiro ekuita inoita basa rakakosha pakuona goho nekuchena kwechigadzirwa chekupedzisira. Kunyatsonzwisisa maitiro ekuita maitiro akabatanidzwa kwakakosha pakugadzirisa maitiro uye kuwana yepamusoro-mhando propylene oxide.
