Alkylation of phenol with methanol over Mg-La-HY-SBA-15 zeolite

Mg-La-HY-SBA-15 zeolite prepared by separate-step impregnation method was used to catalyze alkylation of phenol with methanol. The porous structure and acid property were characterized by SEM-EDS, Py-FTIR and others.The results found that Mg was successfully supported on La-HY-SBA-15 zeolite. Mg-La-HY-SBA-15 had micro-mesoporous structures. Compared with mono-mental modification, bimental modification reduced the amount of total acid and gained more total Lewis acid. At the same time, the selectivity and yield of o-cresol were increased.
