Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for efficiently producing a dioxyalkylene ether of a bisphenol compound containing little amount of by-products and having high purity in industrialization in the method for producing a dioxyalkylene ether of a bisphenol compound from a bisphenol compound.SOLUTION: The method for producing a dioxyalkylene ether (B) of a bisphenol compound (A) by adding a 2-4C alkylene oxide to a bisphenol compound includes a step (I) of carrying out the reaction in the presence of a catalyst (C) in a mixed solvent (S) of water and the following solvent (S1) at a reaction temperature of 30-80°C. The solvent (S1): a solvent capable of dissolving ≥1 g of the dioxyalkylene ether (B) of the bisphenol compound in 100 g of the solvent.
