Estimating the term…
The present invention relates to a process facilitating the regeneration of a catalyst based on a zeolite, employed in an acylation reaction. Another subject of the invention is a process for acylation of an aromatic ether, comprising, in a preferred alternative form, an additional stage of regeneration of the catalyst. The process of the invention, which makes it possible to regenerate more easily a catalyst based on a zeolite, employed in an acylation reaction, is characterized in that the zeolite is modified by addition of an effective quantity of at least one metallic element M chosen from the elements of group 8 of the Periodic Classification of the elements.

Process for acylation of an aromatic ether, which consists in reacting an aromatic ether with an acylating agent, in the presence of a catalyst, and in then recovering the product formed, the said process being characterized in that the acylation reaction is conducted in the presence of an effective quantity of a zeolite modified with at least one element M1 of the platinum group.
Catalyst for acylation of an aromatic ether, including a zeolite modified with an element of the platinum group.
Catalyst for acylation of anisole, including a zeolite β modified with an element of the platinum group.
