propylene oxideimhando yakakosha organic makemikari mbishi zvinhu uye zvepakati.Inonyanya kushandiswa mukugadzirwa kwepolyester polyols, polyester polyols, polyurethane, polyether amine, nezvimwewo, uye chinhu chakakosha chekugadzirwa kwepolyester polyols, iyo inokosha chikamu chepamusoro-performance polyurethane.Propylene oxide inoshandiswawo seyakagadzirwa kugadzirwa kweakasiyana surfactants, madhiragi, makemikari ekurima, nezvimwewo, uye ndechimwe chezvinhu zvakakosha zveindasitiri yemakemikari.

Propylene oxide inogadzirwa neoxidation yepropylene ine catalyst.Iyo mbishi propylene inosanganiswa nemhepo yakamanikidzwa uye yobva yapfuura nemu reactor yakazadzwa necatalyst.The reaction tembiricha kazhinji 200-300 DEG C, uye kumanikidza kunenge 1000 kPa.The reaction product isanganiswa ine propylene oxide, carbon dioxide, carbon monoxide, mvura uye mamwe macompound.The catalyst inoshandiswa mukuita uku ishanduko yesimbi oxide catalyst, yakadai sesilver oxide catalyst, chromium oxide catalyst, etc. Kusarudzwa kwezvinokonzera izvi kune propylene oxide zvishoma, asi basa racho rakaderera.Mukuwedzera, iyo catalyst pachayo ichavharwa panguva yekuita, saka inoda kuvandudzwa kana kutsiviwa nguva dzose.

Kuparadzaniswa uye kucheneswa kwepropylene oxide kubva pamusanganiswa wekuita matanho akakosha mukugadzirisa.Iyo yekuparadzanisa maitiro inowanzo sanganisira kugeza mvura, distillation uye mamwe matanho.Kutanga, musanganiswa wekuita unoshambidzwa nemvura kuti ubvise zvikamu zvakaderera-zvinopisa zvakadai sepropylene isina kushandiswa uye carbon monoxide.Zvadaro, musanganiswa wacho wakanyungudutswa kuti uparadzanise propylene oxide kubva kune zvimwe zvinopisa zvakanyanya.Kuti uwane yakakwirira-kuchena propylene oxide, mamwe matanho ekuchenesa akadai se adsorption kana kudhirowa anogona kudiwa.

Kazhinji, kugadzirirwa kwepropylene oxide inzira yakaoma, inoda matanho akawanda uye kushandiswa kwesimba guru.Naizvozvo, kuti uderedze mutengo uye kukanganiswa kwezvakatipoteredza kweichi chiitiko, zvinodikanwa kuramba uchivandudza tekinoroji uye zvishandiso zvemaitiro.Parizvino, tsvagiridzo yemaitiro matsva ekugadzira propylene oxide inonyanya kutarisisa kune zvakatipoteredza hushamwari maitiro ane kushoma kwesimba uye kugona kwakanyanya, senge catalytic oxidation uchishandisa molecular oxygen seoxidant, microwave-assisted oxidation process, supercritical oxidation process, etc. , tsvakurudzo pamusoro pezvitsva zvitsva uye nzira itsva dzekuparadzanisa zvakakoshawo pakuvandudza goho uye kuchena kwepropylene oxide uye kuderedza mari yekugadzira.
