The Oxynitration of Benzene to Nitrophenols
Abstract
An extensive investigation of the oxynitration of benzene to 2.4-dinitrophenol and/or picric acid by reaction with nitric acid-mercuric nitrate solution was carried out. A new procedure for continuous oxynitration of benzene to dinitrophenol (with some picric acid), utilizing the continuous liquid-liquid extraction principle was developed. An excess of the organic reactant, benzene, serves to remove benzene-soluble organic reaction products from the solution which they are formed, eliminating the necessity of interrupting the operation of the reactor while products are removed. Yields of nitrophenols equal or exceed those obtained by batch procedures, and losses of mercury catalyst are minimized.
