Catalyst precursor prepared from manganese carbonate, and use of a calcined derivative in an ortho-alkylation process |
摘要 |
A catalyst precursor comprised of a dry admixture of manganese carbonate and at least one material selected from among magnesium carbonate, basic magnesium carbonate and magnesium hydroxide. The precursor is calcinable at elevated temperatures to an activated catalyst which may be used in a process for the ortho-alkylation of phenolic compounds.
