How much do you know about the basic knowledge of nickel catalysts? The editor of Maximum Nickel Resistance Catalyst price will take you a brief look.
The preparation process of the nickel catalyst is to treat the nickel aluminum alloy with a concentrated sodium hydroxide solution. In this process, most of the aluminum will react with sodium hydroxide to dissolve away, leaving a very dry activated Raney nickel .With micropores of different sizes. In this way, the surface of Raney nickel is a fine gray powder, but from a microscopic point of view, each tiny particle in the powder is a three-dimensional porous structure. This porous structure greatly increases its surface area, which is caused by the huge surface area. It has high catalytic activity, which makes Raney nickel as a heterogeneous catalyst widely used in hydrogenation reactions in organic synthesis and industrial production.
Raney nickel is mainly used for the hydrogenation of unsaturated compounds, such as alkenes, alkynes, nitriles, diolefins, aromatic hydrocarbons, carbonyl-containing substances, and even polymers with unsaturated bonds. Hydrogenation using Raney nickel sometimes does not even need to add hydrogen specifically, the reaction can be completed only by the large amount of hydrogen adsorbed in the activated Raney nickel. After the reaction, the cis-hydrogenated product is obtained. In addition, Raney nickel can also be used for the reduction of heteroatom-heteroatom bonds. In addition to being a catalyst for hydrogenation, Raney nickel will also act as a reagent to participate in the desulfurization of organic sulfur compounds such as sulfur ketals to generate hydrocarbons.
The above is the editor of Maximum Nickel Resistance Catalyst price: a brief introduction to the basic knowledge of nickel catalyst.
