Ortho-alkylation of phenol derivatives with methanol over magnesium oxide catalysts. 1. Characterization of promoted magnesium oxide catalysts

Cr- and Pt-promoted magnesium oxide catalysts were used to catalyze ortho-alkylation of phenol derivatives in the presence of excess methanol. The characteristic properties of the MgO surface measured by XRD, SEM, BET, and TPD suggest that Cr exists as fine chromium oxide particles on the MgO surfac...
