ABSTRACT:
A process for the acylation of naphthyl ethers of the formula ##STR1## using acylating agents of the formula R.sup.2 --CO--X to give acylated naphthyl ethers of the formula ##STR2## in which R.sup.1 and R.sup.2 independently of one another are C.sub.1 -- to C.sub.10 -alkyl, C.sub.2 -- to C.sub.10 -alkenyl or C.sub.3 - to C.sub.8 -cycloalkyl and R.sup.2 is additionally C.sub.6 - to C.sub.10 -aryl and X is Cl, Br, --OCOR.sup.2, OH or C.sub.1 - to C.sub.3 -alkoxy, comprises carrying out the reaction presence of zeolite catalysts which have the formula Z.Al.sub.2 O.sub.3.x SiO.sub.2 (III) in the anhydrous and template-free form, in which Z is M.sup.I.sub.2 O, M.sup.II O and/or (M.sup.III).sub.2 O.sub.3, in which M.sup.I is an alkali metal atom, ammonium or a hydrogen atom, M.sup.II is an alkaline earth metal atom and M.sup.III is a rare earth metal of atomic number 57 to 71 in the periodic table of the elements, and x is a number from 4 to 4000, with the proviso that at least 50% of the negative lattice charges are compensated by protons, ammonium and/or the other metal ions mentioned under M.sup.II and M.sup.III, and the pores of which are formed from at least 10 tetrahedral atoms.
