Abstract: PURPOSE:To provide an improved process for the industrial production of m- ethylphenol. CONSTITUTION:A sulfonation reaction mixture obtained by the sulfonation reaction of ethylbenzene with sulfuric acid is incorporated with a secondary or tertiary amine and an organic solvent to form a salt of ethylbenzenesulfonic acid and the amine.
