Abstract
A process is provided for the nitrogenation of hydrocarbons, resulting in the production of cyclic imides and nitriles from hydrocarbons contacted with molecular oxygen and a nitrogenating agent, including ammonia or primary amines, in the presence of an oxidation catalyst containing variable valency metal oxides, in the vapor phase at elevated temperature.
Claims14
A process for the direct synthesis of maleimide which does not proceed through maleic anhydride as a intermediate, the process comprising contacting in the vapor phase an unsaturated hydrocarbon having from 4 to about 9 carbon atoms with ammonia and molecular oxygen or a molecular oxygen-containing gas in the presence of an oxidation catalyst having variable valency metal oxides;
- and recovering said maleimide.
