Propylene oxidebụ mmiri mmiri na-enweghị agba na nke na-enweghị atụ nke nwere usoro ihe omimi nke C3H6O. Ọ na-agbaze n'ime mmiri ma nwee ebe isi nke 94.5 ° C. Propylene oxide bụ kemịkal na-emeghachi omume nke nwere ike iji mmiri mee ihe.
Mgbe propylene oxide na-akpọtụrụ mmiri, ọ na-enweta mmeghachi omume hydrolysis iji mepụta propylene glycol na hydrogen peroxide. Nhazi mmeghachi omume bụ nke a:
C3H6O + H2O → C3H8O2 + H2O2
Usoro mmeghachi omume bụ exothermic, na okpomọkụ na-emepụta nwere ike ime ka okpomọkụ nke ngwọta na-ebili ngwa ngwa. Tụkwasị na nke ahụ, propylene oxide dịkwa mfe iji polymerize n'ihu ndị na-emepụta ihe ma ọ bụ okpomọkụ, na polymers ndị a kpụrụ na-adịghị edozi na mmiri. Nke a nwere ike iduga na nkewa nke oge ma mee ka mmiri dị iche iche na usoro mmeghachi omume.
A na-eji propylene oxide mee ihe dị ka ihe eji eme ihe maka njikọ nke ngwaahịa dị iche iche, dị ka surfactants, lubricants, plasticizers, wdg. synthesis, propylene oxide ga-akpachara anya na-echekwa na bufee ka ịzena kọntaktị na mmiri iji gbochie ihe ize ndụ nchekwa.
Tụkwasị na nke ahụ, a na-ejikwa propylene oxide na-emepụta propylene glycol, nke bụ ihe dị mkpa nke etiti maka mmepụta nke polyester fiber, film, plasticizer, wdg. nke dịkwa mkpa ka a na-achịkwa nke ọma na usoro mmepụta iji zere ịkpọtụrụ mmiri iji hụ na mmepụta ihe dị mma.
Na nchịkọta, propylene oxide nwere ike iji mmiri meghachi omume. Mgbe ị na-eji propylene oxide dị ka ihe eji eme ihe maka njikọ ma ọ bụ na-emepụta ihe, ọ dị mkpa ịṅa ntị na nchekwa nchekwa ya na njem iji zere kọntaktị na mmiri na ihe ize ndụ nchekwa.
