Abstract

PURPOSE: To obtain the titled compound which is an intermediate for a reactive dye in high purity and yield, by reacting a urea compound with sulfuric acid or sulfuric acid with fuming sulfuric acid or sulfuric anhydride as a sulfating agent in a small amount close to the theoretical amount while removing the formed water as a by- product outside the reaction system.
CONSTITUTION: A compound of formula I [A is aromatic or heterocyclic compound residue; B is H or -A-(SO2CH2CH2OH)n (n is 1 or 2)] is reacted with sulfuric acid or sulfuric acid and fuming sulfuric acid or sulfuric anhydride in an amount of 1W 3mol SO3 based on one β-hydroxyethylsulfonyl group in the presence or absence of an organic solvent while removing the formed water to give a β-sulfatoethylsulfone compound of formula II. The reaction carried out while removing the formed water to the outside of the system as a by-product without requiring a large excess of sulfuric acid is advantageous to the material of an apparatus. β-Acetoxyethylsulfone derivatives are not formed as by-products due to no formation of acetic acid as a by-product.
