When a solid reduction catalyst prepared by calcining and reducing at 350 DEG to 700 DEG C. in a hydrogen stream a precursor compound having a composition expressed by the following formula MxNiyAlz(OH)2x+2y+ex-tp(A)p.aH2O and having a layer lattice crystal structure characterized by the following X-ray diffraction pattern }d (A) I/Io } 7.5-210.2 100 }3.6-10.6 5 - 80 }2.4-6.4 5 - 60 } IS EMPLOYED FOR HYDROGENATION REDUCTION OF UNSATURATED ORGANIC COMPOUNDS, THE INTENDED REDUCTION PRODUCTS CAN BE OBTAINED AT VERY HIGH CONVERSION AND VERY HIGH SELECTIVITY. |
