| Abstract: | A comparative study on basicity of supported
K-salt catalysts has been carried out for the preparation of trans-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 trans-anethole.
Activation energy for isomerization of methyl chavicol was found to be in the
range of 5.65 –8.67 kJ/mol using 25% K2CO3 loaded on
alumina. The catalysts were characterized by CO2-TPD and BET surface
area. |
