ZINC-CONTAINING ORTHO-ALKYLATION CATALYST PRECURSOR AND CATALYST, AND PROCESS OF USE IN ALKYLATION OF PHENOLS

摘要

ZINC-CONTAINING ORTHO-ALKYLATION CATALYST PRECURSOR AND CATALYST, AND PROCESS OF USE IN ALKYLATION OF PHENOLS Catalyst precursor compositions comprising a mixture of magnesium oxide or a source of magnesium oxide and a water insoluble zinc compound are described. The compositions are calcinable to a catalyst that is useful in reactions for the ortho-alkylation of phenols.
