Raney, also known as Raney nickel, is a highly active catalyst used in various chemical reactions. It is composed of finely divided nickel metal, typically in the form of powder or small granules. The term "Raney" is derived from the name of its inventor, American engineer Murray Raney, who developed this catalyst in the 1920s.
Raney is widely employed in industrial processes such as hydrogenation, where it facilitates the addition of hydrogen atoms to unsaturated compounds. This catalyst works by adsorbing hydrogen gas onto its surface, allowing the reaction to proceed at a lower temperature and pressure compared to non-catalyzed processes. Raney can promote the hydrogenation of various organic substances including alkenes, alkynes, and aromatic compounds, leading to the formation of corresponding saturated compounds.
Besides hydrogenation, Raney is also utilized in other reactions like dehydrogenation, isomerization, and reduction reactions. Due to its unique structure and high surface area, Raney nickel offers increased reactivity and selectivity, making it suitable for a wide range of transformations in the chemical industry. It is commonly employed in the production of pharmaceuticals, petrochemicals, and fine chemicals.
However, it is important to note that Raney is pyrophoric, meaning it can ignite spontaneously upon contact with air. Thus, it should be handled with caution and stored in a controlled environment to prevent accidents.
