Abstract:
A process for the acylation of an aromatic ether which comprises reacting said ether with an acylation agent in the presence of a zeolitic catalyst, said acylation reaction being carried out in the presence of an effective quantity of a catalyst comprising a faujasite type zeolite or a Y zeolite with the following physico-chemical characteristics:an atomic ratio denoted ""global Si/Me.sup.1 "" between the number of atoms of the element silicon and the number of atoms of every trivalent element Me.sup.1 contained in the zeolite in the range 2.4 to 90;an Me.sup.2 alkali metal content such that the atomic ratio Me.sup.2 /Me.sup.1(IV) between the number of atoms of alkali metal Me.sup.2 and the number of atoms of every trivalent element Me.sup.1(IV) included in the zeolitic network is less than 0.2; andan atomic ratio denoted the ""Si/Me.sup.1(IV) of the zeolitic framework"" between the number of atoms of the element silicon and the number of atoms of every trivalent element Me.sup.1(IV) included in the zeolitic network in the range 5 to 100.
