摘要

Alkylation of 4-methoxyphenol with MTBE catalyzed by neutral alumina-supported heteropolyphosphotungstic acids and several other kinds of solid acids was investigated. The results indicate that the reaction activity is correlated with the total acidity of catalysts and the distributions of O-alkylated, mono- and di-C-alkylated products correspond to weak, moderate and strong acidity of catalysts, respectively. They are tunable by supporting different amounts of H3PW12O40 on neutral alumina, and the supported catalysts can be reused.
