Catalyst for alkylation of phenol and a method for producing o-cresol and 2,6-xylenol by using the catalyst

Abstract: A catalyst for alkylation of phenol and a method for producing o-cresol and 2,6-xylenol using the catalyst are provided to stably produce o-cresol and 2,6-xylenol to a high yield even without frequently performing a reactivating operation of the catalyst. A catalyst for alkylation of phenol is represented by the chemical formula 1, Fe1.0VaM1bM2cSidOx, where M1 denotes one or more components selected from the group consisting of cobalt(Co) and nickel(Ni), M2 denotes one or more components selected from the group consisting of manganese(Mn), molybdenum(Mo), zinc(Zn), and magnesium(Mg), catalyst components of Fe, V, M1, M2, and Si are present in the oxide state, a, b, c, and d denote mole ratios of the components V, M1, M2, and Si based on 1 mole of Fe, a ranges from 0.5 to 2, b rages from 0.01 to 0.5, c rages from 0 to 0.5, d rages from 0.01 to 1.0, and x is determined according to values of the a, b, c and d, and oxide states of the components Fe, V, M1 and M2 based on 1 mole of Fe.
