PROCESS FOR THE DIRECT ACETYLATION OF AROMATIC AMINES

摘要

PROCESS FOR THE DIRECT ACETYLATION OF AROMATIC AMINES The present disclosure is concerned with a process of reacting a solid aromatic amine with liquid acetic anhydride to yield a solid amide. The amine is in a flowable particulate form and it is subject to sufficient agitation during the reaction to prevent agglomeration. The amide is recovered as a flowable particulate by evaporation of the acetic acid by product and any excess acetic anhydride.
