摘　　要：聚甲氧基二甲醚是一种理想的新型绿色含氧柴油调和组分,实现该类物质的工业化生产及实际推广应用不仅可充分利用我国过剩甲醇产能部分替代石油,同时能有效缓解雾霾污染,具有重要的经济价值和环保价值。本文综述了国内外关于聚甲氧基二甲醚的研究历程及当前研究进展情况,其中重点介绍了合成聚甲氧基二甲醚的产业发展背景及意义以及该类产品物化特性及优势、定性及定量检测分析方法、合成方法、合成工艺路线及所采用的反应器装置等研究进展,同时介绍了聚甲氧基二甲醚的技术产业化现状,总结了各种方法的特点,分析了聚甲氧基二甲醚的应用拓展及前景,指出聚甲氧基二甲醚在作为柴油调和组分、溶剂和柴油低温流动性改进剂等方面具有很好的应用前景。Polyoxymethylene dimethyl ether（PODEn） are ideal novel green oxygenated diesel blending compounds,which can not only utilize the excess methanol in China but also relieve the air pollution of haze. The present work provided an overview of the progress of PODEn research in China and abroad,with the focus on the research background and significance,advantages of PODEn, properties and quantitatively analysis methods,synthesis methods,process and reactor instruments. Meanwhile,the industrialization status of PODEn were introduced followed by a summarization of the characteristics of different technologies and processes. Finally,potential applications of PODEn were analyzed,and it is prospected that they are favorable to be used as diesel blending compounds,solvents or low temperature flow improver for diesel fuel.
