A asymmetrical aryl ether of the formula X--Ar--O--Ar'--Y, wherein Ar and Ar' are each a divalent aromatic radical, X and Y are electron attracting atoms or groups which differ from each other or have different positions on the corresponding aromatic radicals, is produced by heating together, in the presence of a basic catalyst, equimolecular amounts of two aryl carbonates of the formulas: X--Ar--O--CO--O--Ar--X, and Y--Ar'--O--CO--O--Ar'--Y
