- W2078451322 abstract "As a result of a series of studies, ZnO–Fe2O3 catalysts have been shown to promote the selective methylation (k1) of phenol at the ortho position and also to promote the decomposition of methanol (k2). The activation energies were determined to be 22±2 kcal/mol for the methylation and 27 ±3 kcal/mol for the decomposition. The selectivity factor (S=k1⁄k2) of the simultaneous reaction was determined for five types of catalysts in order to estimate the most favorable catalyst for the methylation. The selectivity factor of these catalysts decrease with the rise in the calcination temperature. For example, the S on the catalysts calcined at 500 °C is approximately at unity but the S on the catalysts calcined at 800 °C is at about 0.4. These results suggest that the calcination using the present catalysts should be controlled at a low temperature." @default.
