Catalyst acid/basic properties regulation to control the selectivity in gas-phase methylation of catechol
1996
Heterogeneous catalysis and fine chemicals IV
The reaction of catechol methylation by methanol in gas-phase over modified g-alumina was studied with the aim to correlate catalytic activity and selectivity to acid/base properties of the catalysts. Catalytic activity and selectivity towards guaiacol formation (O-alkylation) was found to increase with surface acidity. A 20-fold change in the O/C-methylation ratio was achieved by varying the catalyst acid/base properties, keeping const. the other reaction parameters.
