Abstract: The invention provides a method of making a sulfonic group-containing aromatic compound. The multi-substituted sulfonated aromatic compounds can be obtained by reacting an aromatic compound with fuming sulfuric acid having a sulfur trioxide concentration of 20% to 65% by weight) at 120℃ to 250℃ in a closed system with pressure. The multi-substituted sulfonated aromatic compounds are the important monomers necessary for preparing sulfonated poly(ether ether ketone)s (SPEEKs) with higher sulfonation degree, which can be widely used in the field of fuel cell or water treatment.
