  An industrially useful process for the production of an aromatic hydroxy compound which comprises reacting an aromatic sulfonic acid alkali metal salt and/or an aromatic sulfonic acid with an alkali metal hydroxide in the presence of a surface active agent, wherein the reaction is effected by uniformly dispersing these materials in a reaction medium selected from aliphatic, alicyclic and aromatic hydrocarbons. By employing this process, the product can be obtained with high purity, high yield and high selectivity using a minimum amount of the alkali metal hydroxide.
