The primary application of this solid is its use as a reagent & catalyst for many hydrogenation reactions in the field of organic chemistry. Reductive aminations carried out at low pressure with Raney nickel are typically not very successful unless a large amount of catalyst is used. Even after reaction, Raney nickel contains significant amounts of hydrogen gas, and will ignite when exposed to air. However, upon microscopic inspection, it can be observed that each grain of the powder is, by itself, a 3-Dimensional mesh containing pores that are irregular in shape and size. Raney nickel is named after its developer – the American mechanical engineer Murray Raney. Murray Raney graduated as a Mechanical Engineer from the University of Kentucky in 1909. This results in the formation of sodium aluminate and hydrogen gas, as shown in the chemical equation provided below. Raney Nickel catalyst, is extremely fine powdered nickel. Raney nickel is notable for being thermally and structurally stable as well has having a large BET surface area. The aluminium which remains helps to preserve the pore structure of the overall catalyst. Chronic exposure may lead to pneumonitis and other signs of sensitization to nickel like skin rashes ("nickel itch"). During the activation process, aluminium is leached out the NiAl3 and Ni2Al3 phases that are present in the alloy, while most of the aluminium that remains does so in the form of NiAl. The porous structure left behind has a large surface area, which gives high catalytic activity. Believing that better catalysts could be produced, around 1921 he started to perform independent research while still working for Lookout Oil. Additionally, Raney nickel will reduce heteroatom-heteroatom bonds such as nitro groups, and nitrosamines. Some are pyrophoric, most are used as air-stable slurries. Alternatively, the more generic terms " skeletal catalyst" or "sponge-metal catalyst" may be used to refer to catalysts that have physical and chemical properties similar to those of Raney nickel. These properties are a direct result of the activation process and contribute to a relatively high catalytic activity. Raney nickel is used in a large number of industrial processes and in organic synthesis because of its stability and high catalytic activity at room temperature. A patent for this discovery was issued in December 1925. It is also the most versatile of catalysts. Note that the addition of a promoter changes the alloy and its resulting phase diagram to that of a ternary alloy, leading to different quenching and leaching properties during activation. Raney nickel, a reagent, is an alloy of aluminum and nickel, in which much of the aluminum is removed subsequently through a leaching process with sodium hydroxide (NaOH). Alloys are prepared commercially by melting the active metal (nickel in this case, but iron and copper "Raney-type" catalysts can be prepared as well) and aluminium in a crucible and quenching the resultant melt, which is then crushed into a fine powder. The properties of Raney nickel are highly dependent on the activation process followed during the production phase.
