Lactone oxazoline reaction products of hydrocarbon substituted lactone carboxylic acids, for example, polybutyl lactone carboxylic acid, with 2,2-disubstituted-2-amino-1-alkanols, such as tris-(hydroxymethyl)aminomethane (THAM), and their derivatives are useful additives in oleaginous compositions, such as sludge dispersants for lubricating oil, or anti-rust agents for gasoline.
羧酸内酯氧杂环丙氨酸反应产物,例如聚丁基内酯羧酸,与2,2-二取代-2-氨基-1-脂肪醇(例如三羟甲基氨甲烷(THAM))及其衍生物的反应产物在油性组合物中有用,例如用于润滑油的泥浆分散剂或汽油的防锈剂。
