PRODUCTION OF ALKYLATED HYDROXY AROMATIC COMPOUNDS

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. sil...

description 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.
