Abstract
A process and apparatus for reacting deleterious impurities contained in adiponitrile (ADN) comprises feeding ADN and an ozone containing gas into a co-current plug flow reactor containing static mixer elements, to oxidize at least a portion of the impurities, thereby producing a reactor discharge, which is processed to produce an ozone-treated ADN product.
