ABSTRACT:
A catalyst precursor comprising a magnesium compound or material, optionally also containing other metal compounds, is activated for use by calcining at an elevated temperature in the presence of air or nitrogen, or under vacuum. The active catalyst which results may be used in processes for the ortho-alkylation of phenolic compounds, with good yields of and selectivity to the ortho-alkylated end product.
