Abstract
A process is provided for removing peroxide contamination from acrylonitrile. The process includes contacting the acrylonitrile with an activated alumina adsorbent and separating the acrylonitrile product from the alumina. The contaminated acrylonitrile is contacted with the activated alumina adsorbent for a time sufficient for the peroxide contaminate to be adsorbed by the activated alumina. The activated alumina may also be used to selectively remove color promoting contaminates in an acrylonitrile product.
