About Active Nickel Catalyst
Active Nickel is a specialized form of finely divided, porous nickel catalyst prepared by selective leaching of aluminum from a nickel-aluminum alloy under carefully controlled conditions. This process involves treating powdered nickel-aluminum alloy with concentrated caustic soda, resulting in a slurry of spongy nickel particles. These particles are meticulously washed with large amounts of water until nearly free of residual caustic. Due to its pyrophoric nature, Active Nickel is highly flammable when dry and must be stored under water or a suitable solvent such as ethanol, cyclohexane, or dioxane. Commercial transactions, however, are typically conducted on a dry weight basis. Active Nickel is unsuitable for acidic environments below a pH of 5.5, as the nickel particles can dissolve, leading to a reduction in catalytic activity.
Uses and Applications
Active Nickel, with its unique spongy and highly reactive structure, serves as a powerful and versatile catalyst in hydrogenation reactions. It facilitates the hydrogenation of a wide range of functional groups, including carbon-carbon double bonds, carbonyl (aldehyde and ketone) groups, nitro, azide, nitrile, and oxime groups. Its applications span numerous industries such as food processing, pharmaceuticals, aromatics, petrochemicals, rubber additives, dye intermediates, drug intermediates, pesticides, caprolactam production, fine organic chemicals, and reactions involving hydrogenolysis (such as dehalogenation and debenzylation) and desulfurization. This catalyst is effective in both batch and continuous hydrogenation processes and can operate under extreme pressures and temperatures. Active Nickel is considered a non-specific catalyst due to its ability to hydrogenate nearly any reducible functional group in a molecule, often in varying degrees.
Distinct from most hydrogenation catalysts, Active Nickel has resistance to sulfur poisoning. Although it reacts readily with sulfur compounds due to nickel’s strong affinity for sulfur, this trait makes it especially suitable for desulfurization and dehydrogenation reactions.
