<p>Polyalkyl hydroxyaromatics may be prepared from polyalkylenes and hydroxyaromatics in the presence of an acid catalyst and an organic solvent having a boiling point range with an initial boiling point value of below or about the boiling point of the selected hydroxyaromatic reactants and final boiling point of above or equal to about the boiling point of alkylhydroxyaromatic by-product of the reaction. Using this method, accumulation of undesirable alkylhydroxyaromatic by-product/s in a reaction vessel may be minimized, and/or viscosity of polyalkyl hydroxyaromatic product reduced, allowing for increased ease of transfer and transportation.</p> |
