摘要
Abstract
Propylene oxide(PO),as an important chemical intermediate,has seen continuous expansion in global production capacity,but traditional synthesis processes face severe environmental challenges.The chlorohydrin process,for instance,employs chlorine-based oxidants while generating highly corrosive byproducts and significant quantities of"three wastes"(waste gas,wastewater,and residue),directly contradicting green chemistry principles.Conversely,electrocatalytic epoxidation has emerged as an environmentally promising alternative,combining high atom economy with mild reaction conditions(ambient temperature and pressure)and exceptional environmental compatibility,which aligns well with sustainable development objectives.This review provides a comprehensive analysis of the four major PO synthesis processes:the chlorohydrin process,the co-production method,hydrogen peroxide to propylene oxide,and electrocatalysis,comparing their technological principles,industrialization status,and key challenges.Particular attention is given to elucidating electrocatalytic reaction mechanisms and evaluating its scalability for industrial applications.The review provides both theoretical insights and practical guidance for enabling green and low-carbon transformation in PO manufacturing.关键词
