ABSTRACT:
Processes for synthesizing para-nitrodiphenylamines whereby a para-halonitrobenzene is reacted with an aromatic amine selected from the group consisting of formanilides and anilines (substituted and unsubstituted) in the presence of a basic material (to remove acid) are improved by the incorporation of certain select solubilizing agents into the reaction medium. These solubilizing agents are linear, branched, or cyclic polyethers. Some of the resulting advantages are: higher reaction yield, less by-products, and a faster reaction.
