Catalytic methylation of phenol with mixed solvents over Ni/CeO2-La2O3

Ni/CeO2-La2O3 with strong acidity was prepared by in -situ carbon templating (ISCT) and subsequent reduction with H2. The phase composition, specific surface area, morphology, acidity, and elemental valence composition of the catalyst were characterized. The catalytic methylation (CMI) of phenol over the catalyst in different ratios of methanol to n-hexane was investigated under N2 atmosphere. Over the catalyst, phenol was completely converted into 2,6-xylenol at 260 degrees C for 3 h via the CMI of phenol to o-cresol and subsequent CMI of o-cresol.
