Procedure

94 parts by weight of phenol are dissolved in 166 parts by weight of isononanoic acid. 107 parts by weight of 96% sulfuric acid are then added to this solution and the mixture is heated for 30 minutes to 100° to 110° C. The water of reaction is then largely distilled off under reduced pressure (20 mm) within 30 minutes. After cooling, 134 parts by weight of thionylchloride are added dropwise at 45° to 50° C., with addition of an antifoam. The mixture is stirred for one further hour. This gives a stable isononanoyloxybenzenesulfonic acid havingan AS content of 81%, and the Na salt as the end product, which is obtained in virtually quantitative yield (relatative to phenol), has an AS content of 85%.
