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.
一种生产含羟基烷基化芳香族化合物的工艺,包括使具有至少一个羟基的芳香族化合物与烷基化剂反应,其特征在于反应是在液相中在杂多酸存在下进行的。杂多酸(如
硅钨酸)催化剂具有良好的选择性、转化率和产率,基本无腐蚀性,并易于回收再利用。为了达到最佳效率,最好在反应系统中保持一定量的
水。
