NICKEL HYDROGENATION CATALYST AND PREPARATION METHOD THEREOF Russian patent published in 2011 - IPC C07C5/02 B01J23/755 B01J37/04 

FIELD: chemistry.

SUBSTANCE: invention relates to catalytic chemistry - design of an efficient catalyst for hydrogenation of alkenes and a method of preparing said catalyst, which can be used in fine organic synthesis. Described is a catalyst for hydrogenation of unsaturated compounds - alkenes, obtained from a nickel compound and a reducing agent, where the catalyst is obtained using nickel bis-acetylacetonate as the starting nickel compound and lithium tetrahydroaluminate as the reducing agent and a modifying additive is also added - a proton-containing compound selected from a group comprising water, alcohol, phenol or acid, with the following ratio of components: nickel bis-acetylacetonate/lithium tetrahydroaluminate/proton-containing compound 1:2-50:1-34. The invention also describes a method of preparing the catalyst for hydrogenation of unsaturated compounds - alkenes, based on reducing a nickel (II) compound with lithium tetrahydroaluminate, in which the nickel (II) compound used is nickel bis-acetylacetonate, the reducing agent is lithium tetrahydroaluminate and a modifying additive is also added; where the said additive is a proton-containing compound - water, alcohol, phenol or acid; the catalyst is formed in a hydrogen current at temperature 20-35°C (293-308 K) for 5-30 minutes.

EFFECT: preparation of nickel-containing catalyst with high hydrogenation catalytic activity when carrying out the catalytic process in mild conditions (at room temperature and normal (atmospheric) hydrogen pressure or 1 excess atm).
