Process for preparing acyl aminophenols |
abstract |
A process for the production of N-acylaminophenols by the concurrent hydrogenation of a nitrophenol to an aminophenol and the acylation of the aminophenol with acyl anhydride takes place on a continuous basis in a stirred tank reactor in which liquid product is continuously withdrawn from the reactor. Of particular interest is the manufacture of acetaminophen, N-acetyl-p-aminophenol by continuous reaction of p-ntirophenol, hydrogen and acetic anhydride. |
