As　the　clean　fuel　additives,　polyoxymethylene　dimethyl　ethers　(DMMn)could　significantly　reduce　carbonaceous　particulate　matters　and　volatile　organic　pollutants　in　the　exhaust　gas.　Large　scale　production　in　a　green　route　would　be　crucial　if　the　DMMn　tailored　diesel　was　applied　to　the　abatement　of　widespread　PM　air　pollution.　In　the　production,　heavy　components　usually　should　be　separated,　recycled,　decomposed　and　re-reacted　to　gain　the　aimed　products,　which　would　significantly　increase　complexity　and　energy　consumption　of　the　process.　And　fatally,　it　also　might　cause　blockage　of　units　and　pipelines.　In　this　work,　to　prevent　blockage,　the　facile　and　robust　process　producing　DMMn　was　conceptually　designed　basing　on　physicochemical　properties　researches.　The　process　exempting　from　recycle　of　heavy　components　and　de-heavy　column　was　proposed　according　to　cold-flow　properties.　Both　energy　consumption　and　fixed　capital　investment　can　be　saved.　The　reaction　kinetic　model,　which　was　described　in　the　form　of　power　law　functions,　showed　good　consistency　for　both　propagation　and　depolymerization　reactions.　Flash　points　of　diesel　blends　were　also　measured　for　determining　specification　of　light　components.　This　work　shows　it　is　feasible　that　DMMn　can　be　produced　from　dimethoxy　methane　and　trioxane　in　the　presence　of　acid　functionalized　ionic　liquids　in　large　scale.　©　2019　Elsevier　Ltd
