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.
一种用于生产芳香族羟基化合物的工业实用工艺,包括在表面活性剂存在下,使芳香族磺酸碱金属盐和/或芳香族磺酸与碱金属氢氧化物反应,其中反应是通过将这些材料均匀分散在选自脂肪烃、脂环烃和芳香烃的反应介质中进行的。采用这种工艺,只需使用极少量的碱金属氢氧化物,就能获得高纯度、高产率和高选择性的产品。
