| titleOfInvention | Method for producing dialkylbenzenesulfonic acid, method for producing dialkylbenzenesulfonic acid salt, and method for producing dialkylphenol |
| abstract | (57) [Problem] To provide a method for selectively producing various isomers when a dialkylphenol is obtained by an alkylation reaction from phenol or alkylphenol. Another object of the present invention is to provide a method for producing a highly pure dialkylbenzene sulfonic acid or a salt thereof in a high yield with a small number of isomers. SOLUTION: The method for producing dialkylbenzene sulfonic acid or a salt thereof is carried out at a reaction temperature of 80 ° C. or less when sulfonating dialkylbenzene with sulfuric acid. Also, a method for producing a dialkylphenol, which is obtained by obtaining a dialkylbenzenesulfonic acid or a salt thereof by this method, followed by alkali hydrolysis. |
