Abstract: The present invention relates to a method for purifying phenol, which comprises: contacting a phenol stream comprising hydroxy acetone, 2-methylbenzofuran, 3-methylbenzofuran and phenol with an acyl chloride in the presence of an organic sulfonic acid to convert one or more selected from the group consisting of hydroxyacetone, 2-methylbenzofuran and 3-methylbenzofuran into a high boiling point compound having a boiling point higher than that of the phenol; and recovering the high boiling point compound from the phenol stream.
