PROBLEM TO BE SOLVED: To provide a method of purifying 2,6-dimethyl phenol useful for production of a low-odor poly(arylene ether) resin. SOLUTION: The method of purifying 2,6-dimethylphenol comprises a step of distilling a mixture containing 2,6-dimethyl phenol and 2,4,6-trimethylanisole to yield a first light fraction enriched in 2,6-dimethylphenol and a first heavy fraction enriched in 2,4,6-trimethylanisole; and a step of distilling the first light fraction to yield a second light fraction and a second heavy fraction enriched in 2,6-dimethylphenol, wherein the concentration of 2,4,6-trimethylanisole in the second heavy fraction is less than 50% of the concentration of 2,4,6-trimethylanisole in the mixture.
