Abstract

PURPOSE: To obtain the titled compound in high purity and yield, by reacting an aminoaryl β-hydroxyethyl sulfone or acetylaminoaryl β-hydroxyethyl sulfone with sulfuric acid in a specific apparatur white removing water etc.
CONSTITUTION: an aminoaryl β-hydroxyethyl sulfone or acetylaminoaryl β-hydroxyethyl sulfone is reacted with sulfuric acid in a molar amount of 1W2 times that of the sulfone at 50W250°C in an apparatus capable of removing a volatile component by gasification or evaporation, while removing water or water and acetic acid to give an aminoaryl β-sulfatoethyl sulfone. 4-(Amino or acetylamino) phenyl β-hydroxyethyl sulfone may be cited as the starting material.
EFFECT: The high-purity product can be obtained with sulfuric acid in a smaller amount than ever before.
USE: An intermediate for vinyl sulfone reactive dyes.
