摘要
The present invention relates to a process facilitating the regeneration of a zeolithe-based catalyst used in an acylation reaction. The invention also relates to a process for the acylation of an aromatic ether, comprising in a prefered alternative, an additional step of regeneration of the catalyst. The process of the invention which improves the regeneration of a catalyst based on a zeolithe and used in an acylation reaction is characterized in that the zeolithe is modified by adding an efficient amount of at least one metal element M selected amongst the element of group 8 of the periodic classification of elements.
