Abstract:


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.

Keywords:
