Abstract: A comparative study on basicity of supported K-salt catalysts has been carried out for the preparation of <i style="">trans-</i>anethole [1-methoxy-4-(1-propen-1-yl) benzene]. It is observed that strong basic sites facilitated 99% conversion of methyl chavicol [1-methoxy-4-(2-propen-1-yl) benzene] with 89% selectivity of <i>trans</i>-anethole. Activation energy for isomerization of methyl chavicol was found to be in the range of 5.65 –8.67 kJ/mol using 25% K<sub>2</sub>CO<sub>3</sub> loaded on alumina. The catalysts were characterized by CO<sub>2</sub>-TPD and BET surface area.
