A catalyst precursor composition for forming a phenol alkylation catalyst, the composition comprising: 70 to 98 weight percent of abase oxide comprising: magnesium oxide with a Brunauer-Emmett-Teller surface area from 75 meter2/gram to 220 meter2/gram, preferably from 75 meter2/gram to 140 meter2/gram, more preferably from 90 meter2/gram to 130 meter2/gram; or magnesium carbonate with a Brunauer-Emmett-Teller surface area of from 100 meter2/gram to 220 meter2/gram, preferably from 120 meter2/gram to 200 meter2/gram; or a combination thereof; at least one metal promoter precursor comprising an iron precursor, a manganese, a vanadium precursor, or a copper precursor; and a pore former, a lubricant, a coke inhibitor; and optionally, a strength additive; and optionally a binder, and a method of alkylating phenol using a catalyst derived from the catalyst precursor.
