    • An improved process to prepare poly(oxyalkylene)amide for gasoline additives involves three consecutive reactions. The reactions are (1) amidation of water-soluble low molecular weight of polyalkylene polyamine with alkyl acetate at an elevated temperature under N2 pressure to convert amines to amides, (2) Butoxylation of the amides with 1,2-epoxybutane to prepare the poly(oxyalkylene) amides, and (3) selective hydrolysis of in situ poly(oxyalkylene)-amine-ester-amides into poly(oxyalkylene)-amine-alcohol-amides and removal of acetic acid byproducts, via acid/base hydrolysis and water extraction procedures. The process step of selective hydrolysis is essential for removal the harmful composition of poly(oxyalkylene)-amine-ester-amides in resulting the better performance of the additive, particularly the positive engine's octane requirement or reducing the combustion chamber deposits. More specifically the butoxylation process generally produces poly(oxyalkylene)amides and poly(oxyalkylene)esters via an exchange reaction (trans-amidation/trans-esterification) and the poly(oxyalkylene)esters in the product mixtures is removed to obtain better performance products.
    • 制备用于汽油添加剂的聚(氧化烯)酰胺的改进方法包括三次连续的反应。 反应是(1)在氮气压力升高的温度下,将水溶性低分子量聚亚烷基多胺与烷基乙酸酯进行酰胺化以将胺转化为酰胺,(2)用1,2-环氧丁烷对酰胺进行丁氧基化以制备聚 (氧化烯)酰胺,和(3)通过酸/碱水解和水提取将原位聚(氧化烯) - 胺 - 酯 - 酰胺选择性水解成聚(氧化烯) - 胺 - 醇 - 酰胺和除去乙酸副产物 程序。 选择性水解的工艺步骤对于去除聚(氧化烯) - 胺 - 酯 - 酰胺的有害组合物是必不可少的,从而获得更好的添加剂性能,特别是正发动机的辛烷值要求或减少燃烧室沉积物。 更具体地,丁氧基化方法通常通过交换反应(反式酰胺化/反式酯化)产生聚(氧化烯)酰胺和聚(氧化烯)酯,并且除去产物混合物中的聚(氧化烯)酯以获得更好的性能产物。

    • The present invention is one kind of gasoline additives. The compounds consist of tertiary amine, amide and poly(oxybutylene) backbone in the same molecule. The process of making this type of products required an initiator containing primary amine and tertiary amine as the starting diamines. The primary amine will be converted into amide, while the tertiary amine remained intact. Then the amide is converted into butoxylates through butoxylation at CON—H position. The preparation therefore involved two steps: (1) amidation of diamines containing primary/tertiary amines with ethyl acetate to form amidoamines, and (2) butoxylation of this amidoamines to poly(oxybutylene)amidoamine. The product is gasoline soluble and can be used as additive having good performance of detergency and octane requirement reduction.
    • 本发明是一种汽油添加剂。 该化合物由同一分子中的叔胺,酰胺和聚(氧丁烯)主链组成。 制造这种类型的产物的方法需要含有伯胺和叔胺的引发剂作为起始的二胺。 伯胺将转化为酰胺,而叔胺保持完整。 然后通过在CON-H位置的丁氧基化将酰胺转化成丁酸盐。 因此,该制剂涉及两个步骤:(1)使用乙酸乙酯将二胺与二乙胺进行酰胺化以形成酰氨基胺,和(2)将该酰氨基胺丁酰化成聚(氧丁烯)酰氨基胺。 该产品是汽油可溶性的,可用作具有良好洗涤性能和辛烷值要求降低性能的添加剂。
