A process for producing a hydroxy-containing alkylated aromatic compound comprising reacting aromatic compound having at least one hydroxyl group with alkylating agent characterised in that the reaction is conducted in the liquid phase in the presence of heteropoly acid. The heteropolyacid (e.g. silicotungstic acid) catalyst gives good selectivity, conversion and yields, is substantially non-corrosive, and is readily recovered for re-use. A regulated amount of water is preferably maintained in the reaction system for best efficiency.
This invention relates to a hydroxyaromatic functionalized polyalpha-olefin comprising the product of the combination of:
a) a polyalpha-olefin comprising one or more C3 to C20 linear alpha-olefins and having at least 10% vinylidene unsaturation, a viscosity index of 80 to 400, an Mn of 300 to about 20,000, and a pour point of 0° C. or less; and
b) a hydroxyaromatic moiety;
wherein the analine point of the functionalized polyalpha-olefin is at least 10° C. lower than the analine point of the polyalpha-olefin.
