AbstractNew monodisperse nonionic surfactant molecules, based on lysine with two fatty acid chains in the hydrophobic part and one or two polyoxyethylene methoxycapped chains (EOn−Me) in the hydrophilic headgroup, are synthesized as mimics of natural lecithins. Their surface‐activity properties indicate that these compounds have surfactant behavior whose global hydrophobic contribution is comparable to that of one fatty chain.
摘要 作为天然卵磷脂的模拟物,合成了新型单分散非离子表面活性剂分子,这些分子以赖氨酸为基础,疏水部分含有两条脂肪酸链,亲水头团含有一条或两条聚氧乙烯甲氧基封端链(EOn-Me)。它们的表面活性特性表明,这些化合物具有表面活性剂特性,其总体疏水性与一条脂肪链的疏水性相当。
