The turn over frequency on the catalysts is several times higher than the other previously reported catalysts. Also, thermal gravimetric analysis and powder X-ray diffraction pattern of the catalysts have been studied.

salt (1-carboxymethyl-3-methylimidazolium bromide {[cmmim]Br} as a reusable catalysts is reported. In
addition, thermal gravimetric analysis (TGA), differential thermal gravimetry (DTG), powder X-ray diffraction (PXRD) and calculation of size and inter planer distance of the catalyst have been studied in this work.
