摘　　要：介绍了聚甲氧基二甲醚作为新型高十六烷值柴油调和组分的基本性质、合成方法及合成机理,综述了近年来国内外合成聚甲氧基二甲醚催化剂的主要研究成果,分析了各催化剂反应优缺点及催化剂酸性对产物分布的影响规律。提出调变固体酸催化剂酸性,是今后研究合成聚甲氧基二甲醚催化剂的重要方向。The properties, synthesis, and mechanism of chain propagation for synthesis of polyoxymethylene dimethyl ethers as the component of high-cetane number diesel fuel are introduced. The progress of catalyst for polyoxymethylene dimethyl ethers in recent years is reviewed. The advantages and disadvantages of the catalyst are analyzed. The effect of acidity of the catalysts on the distribution of the product is discussed. Adjusting the acidity of the catalyst is proposed as an important way for synthesis of polyoxymethylene dimethyl ethers.
