Abstract:
1. A process for preparing an alkylated hydroxyl aromatic compound comprising reacting (a) a hydroxyl aromatic compound (I), having the following structure; wherein n 1, 2 or 3; m is 0, 1, 2, or 3 and R 1 is Hydrogen or hydrocarbyl group and (b) at least one β-branched primary alcohol in the presence of an ionic liquid catalyst or an acidic alkylating catalyst selected from the group consisting of natural zeolites, synthetic zeolites, synthetic molecular sieves, clays, and ion exchange resins, thereby producing an alkylated hydroxyl aromatic compound wherein the alkylated hydroxyl aromatic compound comprises at least about 65 to 98 weight percent of a para-substituted hydroxyl alkylated aromatic isomer.
