Short summary:

To provide a new catalyst characterized by using nickel phosphide nanoparticles as the active ingredient to resolve the problems of sponge catalysts conventionally used for the hydrogenation of organic compounds.

Description:

This invention involves a catalyst comprised of nickel phosphide nanoparticles as the active ingredient, a method for producing hydrogenated compounds using this catalyst, and a method for producing open-chain compounds.
It is generally known that high surface area nickel or cobalt sponge catalysts are used when nickel or cobalt is used as a catalyst. Sponge catalysts are very unstable in the atmosphere and pose a high fire risk. Therefore, it is necessary to carry out preparation of the catalyst, substitution of the solvent, and all reaction processes in an anaerobic atmosphere. It is also necessary to strictly avoid contact with the atmosphere during storage and to store the sponge in water or alcohol. In industrial applications, it is stored as a metal alloy serving as a catalyst, such as cobalt, and a metal alloy that is dissolved and removed by an acid or alkali in which the metal does not dissolve.
  The inventors have found that the above problems can be solved by using a catalyst containing nickel phosphide nanoparticles as the active ingredient.
  The catalyst used for hydrogenation in this invention is very stable in the atmosphere and poses no fire risk. The method for producing the hydrogenated organic compound used in this invention can be used for the production of hydrogenated organic compounds and open-chain compounds at high conversion and yield rates. Further, in the method for producing the hydrogenated open-chain compounds used in this invention, hydrogenation and the formation of the open-chain compounds can be done in one step and can be produced at high conversion and yield rates.
   This catalyst is a safe alternative to conventional sponge catalysts, and is expected to be effective in all accelerated catalytic reactions using conventional sponge catalysts. Catalytic reactions include, for example, hydrogenation of unsaturated compounds with double or triple bonds, carbonyl compounds including aldehydes and ketones, nitrile compounds and nitro compounds, etc., hydrogenation of aromatic compounds and heterocycles, dehalogenation, the production and hydrogenolysis of lactams, reduction animation and hydrogenation of various organic compounds.

Benefits Description:

The catalyst used for hydrogenation in this invention is very stable in the atmosphere and poses no fire risk. The method for producing the hydrogenated organic compound used in this invention can be used for the production of hydrogenated organic compounds and open-chain compounds at high conversion and yield rates. Further, in the method for producing the hydrogenated open-chain compounds used in this invention, hydrogenation and the formation of the open-chain compounds can be done in one step and can be produced at high conversion and yield rates.
As a result, based on this invention, the energy required for the storage of the catalyst and the production of hydrogenated organic compounds and open-chain compounds can be greatly reduced, also helping to reduce environmental load by mitigating the release of greenhouse gases, etc.
