Propylene oxideikemikari yakashandiswa zvakanyanya, iyo inonyanya kushandiswa mukugadzirwa kwepolyether polyols, polyurethanes, surfactants, nezvimwewo. Iyo propylene oxide inoshandiswa pakugadzira zvigadzirwa izvi inowanzowanikwa kuburikidza neoxidation yepropylene ine siyana-catalysts. Nokudaro, mhinduro kumubvunzo wekuti propylene oxide inogadzirwa ndeye hongu.

Epoxy propane kuchengetedza tangi

 

Chokutanga pane zvose, ngatitarisei kunobva propylene oxide. Propylene oxide imhando yakakosha kemikari yakabikwa inotorwa kubva kupropylene. Propylene imhando yeolefin inowanikwa nekupwanya peturu, uye chimiro chayo chemolecular inoumbwa chete kabhoni nehydrogen. Naizvozvo, propylene oxide synthesized kubva kupropylene zvakare imhando yeorganic compound inoumbwa chete kabhoni nehydrogen.

 

Chechipiri, isu tinogona zvakare kuongorora maitiro ekugadzira epropylene oxide. Iyo synthetic process yepropylene oxide inowanzo shandisa zvakasiyana-siyana zvinokonzeresa kuita oxidation reaction yepropylene pasi pekushisa kwepamusoro uye kudzvinyirira kwakanyanya. Pakati pavo, chinonyanya kushandiswa chinokonzera sirivha. Mukuita kwekuita oxidation reaction, propylene uye oxygen mumhepo zvinogadziriswa nesirivha kuti ibudise propylene oxide. Pamusoro pezvo, zvimwe zvinokonzeresa senge titanium dioxide uye tungsten oxide zvakare zvinowanzoshandiswa pakugadzira propylene oxide.

 

Pakupedzisira, isu tinogona zvakare kuongorora mashandisirwo epropylene oxide. Propylene oxide inonyanya kushandiswa mukugadzirwa kwepolyether polyols, polyurethanes, surfactants, nezvimwewo. Zvigadzirwa izvi zvinoshandiswa zvakanyanya muhupenyu hwezuva nezuva, senge polyurethane foam yekudzivirira uye kusagadzikana kwekuvhunduka, polyether polyols epoxy resins, surfactants yekuchenesa uye kuwacha. Nokudaro, kushandiswa kwepropylene oxide kwakafara zvikuru.

 

Zvichienderana neongororo iri pamusoro, tinogona kugumisa kuti propylene oxide chigadzirwa chakatorwa kubva kupropylene kuburikidza neoxidation reaction ine akasiyana catalysts. Kunobva kwayo, maitiro ekugadzira uye mashandisirwo ese ane hukama nehupenyu hwevanhu uye zviitiko zvekugadzira.
