Abstract:

This paper systematically studied the material compatibility, storage stability, and miscibility with diesel fuel of polyoxymethylene dimethyl ethers (PODE n ) from the point of view of its application performance. The results show that the PODE n is generally highly compatible with common metal materials, such as copper, brass, steel, cast iron, cast aluminum, and solder. In comparison, blended diesel fuel with PODE n at a volume fraction of 10% is highly compatible with polyester polyurethane rubber and fluororubber but poorly compatible with nitrile rubber and polyether polyurethane rubber. In the storage stability test conducted at 43 °C for 16 weeks, PODE n demonstrates satisfactory storage stability. Excellent miscibility stability occurs after the blending of automobile diesel fuel with PODE n at a volume fraction of 10%. In general, as a component of blended diesel fuel, PODE n delivers satisfactory application performance.

Key words: Polyoxymethylene dimethyl ethers, Material compatibility, Storage stability, Miscibility with diesel fuel

摘要:

从聚甲氧基二甲醚使用性能的角度,对其材料相容性、贮存安定性、与柴油的互溶性等进行了系统研究。结果表明,聚甲氧基二甲醚与常见的铜、黄铜、钢、铸铁、铸铝和焊料等金属材料的相容性总体良好,体积分数为10%的聚甲氧基二甲醚调合柴油与聚酯型聚氨酯橡胶和氟橡胶的相容性相对较好,与丁腈橡胶和聚醚型聚氨酯橡胶的相容性相对较差;在16周的43 ℃贮存安定性实验中,聚甲氧基二甲醚表现出良好的贮存安定性;将聚甲氧基二甲醚按照体积分数为10%的比例与车用柴油掺混后,二者具有良好的互溶稳定性。总体来说,聚甲氧基二甲醚作为柴油调合组分表现出良好的使用性能。
