Raney-Nickel is widely used as a catalyst in hydrogenation reactions, particularly in the reduction of unsaturated organic compounds such as alkenes, nitriles, and carbonyls. It is highly effective under mild conditions and commonly employed in the production of fine chemicals, pharmaceuticals, and agrochemicals. One of its key applications is in the conversion of nitriles to primary amines, which are important building blocks in drug synthesis. It is also used in desulfurization processes, such as removing sulfur from organic compounds in petroleum refining. Due to its high surface area and activity, Raney-Nickel facilitates efficient and selective hydrogen uptake, making it valuable in both laboratory and industrial-scale reactions. Safety precautions are necessary due to its pyrophoric nature when dry.
