Abstract

PURPOSE: To prepare the title compound useful as an intermediate of dye, with low sulfuric acid consumption, in high yield, by heating a specific hydroxyethyl sulfone in sulfuric acid while distilling out the water and acetic acid under reduced pressure.
CONSTITUTION: Acetylaminoaryl-β-hydroxyethyl sulfone is heated (usually at 60W 150°C) in sulfuric acid to obtain the intermediate product. The intermediate is reacted at high temperature while distilling out the water and produced acetic acid under reduced pressure to obtain aminoaryl-β-sulfate ethyl sulfone which is an intermediate of a vinylsulfone-type reactive dye. The molar ration of the sulfuric acid to the starting material is 2W5. The concentration of the sulfuric acid is 50W 100%, pref. 60W90%, from the economical standpoint.
