Abstract

PURPOSE: The reaction of aminoaryl-β-hydroxyethylsulfon with sulfuric acid is effected by distilling off water and acetic acid, by-products, azeotropically to produce high-purity titled compound used as a dye intermediate in high yield with a small amount of sulfuric acid consumption.
CONSTITUTION: The reaction between aminoaryl-β-hydroxyethylsulfone acetylaminoaryl-β-hydroxyethylsulfone and sulfuric acid is effected under azeotropic distillation of water or water and acetic acid formed as by-products at normal or reduced pressure to produce aminoaryl-β-sulfatoethylsulfone. Since water and acetic acid is distilled off to the outside of the reaction system, the concentration of sulfuric acid is kept at a desired level. The starting material may content water and the pollution caused by waste water is reduced.
