PYRIDINIUM P-TOLUENESULFONATE IONIC LIQUID: SYNTHESIS, CHARACTERIZATION, AND APPLICATION AS CATALYST IN ETHANOL-BASED TRANSESTERIFICATION OF BABASSU OIL

This paper describes the synthesis of the ionic liquid (IL) pyridinium p-toluenesulfonate [HPy][p-TSA], and its characterization as a catalyst in biodiesel production via ethanol-based transesterification of babassu oil. The IL was characterized by FT-IR, ¹H NMR, TG-DSC, and Single-crystal XRD. [HPy][p-TSA] showed an o...
