PCT No. PCT/FR96/00717 Sec. 371 Date Jan. 9, 1997 Sec. 102(e) Date Jan. 9, 1997 PCT Filed May 10, 1996 PCT Pub. No. WO96/35656 PCT Pub. Date Nov. 14, 1996The present invention concerns a process for the acylation of an aromatic ether. Preferably, the invention relates to a process for the acylation of an unsubstituted aromatic ether, in particular anisole. The acylation process of the invention consists of reacting the ether with an acylation agent in the presence of a zeolitic catalyst, and is characterized in that the acylation reaction is carried out in the presence of an effective quantity of a catalyst comprising a beta zeolite with an atomic ratio denoted "global Si/Me1" between the number of atoms of the element silicon and the number of atoms of every trivalent element Me1 contained in the zeolite of no less than 15, preferably in the range 15 to 55, and more preferably in the range 18 to 35.
