摘要

Supported ionic liquids (SILs) can be prepared by immobilizing ionic liquids (ILs) onto solid support materials. SILs have proved to be quite efficient in numerous organic transformations as organocatalyst, desulfurization, and gas separations. In comparison with pure ILs, SILs offer advantages such as easier recovery and lower drawbacks. The drawbacks include high cost, toxicity, and also difficulty in product purification. For the very first time, Xanthan Gum SIL (XGSIL) was synthesized by immobilizing IL onto backbone of xanthan gum (XG), which is the most prevalent polysaccharide in nature and economical in industrial waste by using ultra probe sonicator. XGSIL was characterized using a variety of methods including FT-IR, SEM, EDS, TGA and CHN analysis. Further, the synthesized XGSIL was used as an organocatalyst for the synthesis of biologically important thiazole derivatives under ultrasonication. This methodology points out a simple process that is very applicable, high yield (> 95%), shorter reaction time (3–14 min), environmentally friendly, recyclability and reusability of catalyst up-to seven times without significant loss in its catalytic activity.
