The demand for selective catalysts with larger molecular dimensions led to the discovery of mesoporous catalytic materials. We report herein the development of an environmentally friendly process for C-methylation of phenol derivatives with methanol using mesoporous ceria modified with transition metals. Selective C-methylation of phenol, has been investigated over transition metals loaded mesoporous ceria. Catalyst reaction rates at various reaction parameters were also investigated. 98% selectivity for ortho-alkylated products (o-cresol and 2, 6-xylenol) was obtained. The reaction is proved to be first order with phenol conversion. The frequency factor A and the activation energy Ea were also evaluated with (CeFe10%) catalyst.
