ABSTRACT:
A process for the sulfonation of an aromatic compound wherein the aromatic compound and sulfonating agent are admixed in the presence of an ionic liquid is described. The method for the sulfonation of aromatic compounds in (e.g. water stable) ionic liquids offers advantages over conventional sulfonation reactions. These are that no by-products form, the ionic liquid is not consumed, and the sulfonating agent (e.g. SO3) is relatively inexpensive.
