Dioctyl sodium sulfosuccinate (DOSS) as a unique material both as a drug and surfactant was synthesized by a facile and economical synthetic method. In this project, Amberlyst-15 was selected as a heterogeneous recyclable bronsted solid acid for this synthesis both in the esterification of maleic anhydride and sulfonation of dioctyl maleate (DOM) ester. This catalyst was easily recovered and reused at least for 13 consecutive cycles without a significant loss in the catalytic activity. In this paper, we wish to uncover a catalytic approach for the synthesis of DOSS through a recyclable, easily recoverable, and commercially available catalyst, namely Amberlyst 15, under mild conditions.

通过简便，经济的合成方法合成了磺基丁二酸二辛酯钠（DOSS）作为药物和表面活性剂的独特材料。在该项目中，选择Amberlyst-15作为马来酸酐的酯化和马来酸二辛酯（DOM）的磺化反应中合成的异质可循环布朗斯台德固体酸。该催化剂易于回收并至少连续13个循环重复使用，而催化活性没有明显损失。在本文中，我们希望揭示一种在温和条件下通过可循环利用，易于回收且可商购的催化剂Amberlyst 15合成DOSS的催化方法。
