Abstract
Disclosed is a process for the preparation of dialkyl aromatic hydroxyl compounds such as dialkylphenols, dialkylbenzenediols, dialkylnaphthols and dialkylnaphthalenediols, especially 2,5-dialkylhydroquinone, by contacting an aromatic hydroxy compound with an olefin in the presence of a sulfonic acid and sulfuric acid.
