The mode of combination of the copper-chromium-manganese oxide catalysts by the X-ray diffraction data is as follows; the standard catalyst (KW-1) was consisted of CuO and CuCr₂O₄ combined with manganese oxide, and KW-6, treated with hot HCl to remove CuO, was also CuCr₂O₄ combined with manganese oxide. The results were closely checked by the standard gravimetric analysis. The activity and selectivity of KW-6 on the unsaturated bond of unsaturated fatty oils were superior compared to those of CuO+CuCr₂O₄ (Adkins catalyst) and CuO prepared by the wet method. The results of these facts demonstrate that the CuCr₂O₄ combined with manganese oxide is the true catalyst for the selective hydrogenetion of unsaturated fatty oils.
