PCT No. PCT/SE85/00399 Sec. 371 Date Jun. 20, 1986 Sec. 102(e) Date Jun. 20, 1986 PCT Filed Oct. 17, 1985 PCT Pub. No. WO86/02634 PCT Pub. Date May 9, 1986.A method is disclosed for the dealkylation of alkylaryl ethers by reaction with aluminum triodide under reflux. The reaction is carried out in the presence of a catalytic amount of a quaternary ammonium iodide in a substantially non-aqueous organic solvent. The reaction product is then hydrolyzed with water. The quaternary ammonium iodide can be of the formula R4N+I-, wherein R is alkyl, and the solvent is preferably benzene or cyclohexane.
