汽油清净分散剂聚醚胺的合成及应用

用高压催化氨化法合成了聚醚胺，研究了反应温度、反应压力、反应时间对反应转化率的影响。研究结果表明，在催化剂加入量（w）为8%、氢气初始分压为1.0MPa、反应温度220 ℃、反应压力13.5 MPa、反应时间4 h的条件下，聚醚氨化制聚醚胺转化率达到97.5%。通过模拟试验和台架对比试验测试了聚醚胺的清净分散性能。结果表明，聚醚胺不仅能有效地清洁发动机进气阀部位沉积物， 而且能抑制燃烧室沉积物增加。

SYNTHESIS AND APPLICATION OF POLYETHERAMINE AS GASOLINE DETERGENT

A kind of polyetheramine was synthesized by high pressure catalytic amination.Effects of the reaction conversion in temperature，pressure and time were investigated.In the presence of H2 and catalyst, temperature of 220 ℃, pressure of 13.5 MPa, and reaction time of 4 h, the conversion of the polyether was above 95 %. The product was characterized by IR. The results of simulated experiments and engine bench scale tests show that the polyetheramine have the outstanding lustration performance of engine intake valve, besides also can restrain the production of combustion chamber deposit effectively.
