In this study, each of the two hydroxyl groups of isosorbide moieties have synthesized selective endo and exo forms by allylation and alkylation. New method is proposed for the synthesis of isosorbide-based sulfonate anionic surfactants with hexyl, octyl, decyl, and dodecyl alkyl chains. Compared to the traditional synthesis routes, the new reactions are more efficient, simpler, highly selective, and provide higher yield and comparable purity. The two series of synthesis products are endo-5-O-alkyl isosorbide-2-O-propyl sulfonate sodium salt(ENISS-n) and exo-2-O-alkyl isosorbide-5-O-propyl sulfonate sodium salt(EXISS-n). The synthesized surfactants have been tested to critical micelle concentration, foaming test and emulsion property. |
