    • An aromatic ether acylation process is described, particularly a process for acylating a substituted aromatic ether and more particularly veratrol. The method of the invention includes reacting the ether with an acylation agent in the presence of a zeolite catalyst, and is characterised in that the acylation reaction is conducted in the presence of an effective amount of a catalyst containing a faujasite type zeolite or zeolite Y with the following physical and chemical characteristics: an atomic ratio, designated as "global Si:Me ", between the number of atoms of the silicon component and the number of atoms of any trivalent component Me contained in the zeolite, in the range of 2.4 to 90, preferably of 2.4 to 75 and even more preferably of 2.4 to 60, and an alkali metal Me content such that the atomic ratio Me :Me between the number of atoms of the alkali metal Me and that of any trivalent component Me contained in the zeolite matrix, is lower that 0.2, preferably lower than 0.1 and even more preferably, lower than 0.05.
    • 描述了芳族醚酰化方法,特别是用于酰化取代的芳族醚,更特别是藜芦醇的方法。 本发明的方法包括使醚与酰化剂在沸石催化剂存在下反应,其特征在于酰化反应在有效量的含有八面沸石型沸石或沸石Y的催化剂存在下进行, 以下物理和化学特性:在硅组分的原子数与沸石中所含的任何三价组分Me 1的原子数之间的原子比,称为“全局Si:Me <1” 在2.4至90,优选2.4至75,甚至更优选2.4至60的范围内,并且碱金属Me 2的含量使得原子比Me 2之间的原子比Me 2(IV) 包含在沸石基质中的碱金属Me 2和任何三价组分Me <1(IV)>的原子数小于0.2,优选低于0.1,甚至更优选低于0.05。
