Abstract

Process for the production of unsaturated nitriles, by reaction in a gas phase of olefins with oxygen and ammonia at a temperature in the range between 350 and 550º C in the presence of the usual ammoxidation catalysts, characterized in that the active elements of the catalyst are supported on a support composed of preconfigured silica having an average pore diameter of the range of 40 to 200 Å (Machine-translation by Google Translate, not legally binding)
