METHOD OF ACYLATING AN AROMATIC COMPOUND.

摘要

The present invention relates to a method of acylating a substituted aromatic compound. The substituted aromatic compound is reacted with an acylating agent in the presence of a macroreticular sulfonic acid ion exchange resin having a water-to-phenol shrinkage between 25 % and 40 %. The method is very advantageous in that the resin is deactivated much less than other resins without a fast drop in conversion and selectivity in the reaction.
