FIELD: chemistry.
SUBSTANCE: invention relates to processes of catalytic hydration. Claimed is catalyst for liquid-phase hydration of organic substances of various classes i.e. nitro-compounds, aldehides, unsaturated and aromatic compounds, with molecular hydrogen, which includes unit-type carrier of low density and high porosity and metallic palladium. Carrier is made from aluminium oxide by method of doubling foam-polyurethane matrix by impregnating it with slip Al2O3 with further calcination. Layers of γ-Al2O3 are applied on carrier successively in such a way that weight of active layer from γ-Al2O3 is not less than 6% of total weight of catalyst, and of metallic palladium in amount of 0.16-3.7%. Alternatively, instead of γ-Al2O3 layer, layer of sulphated oxide of titanium or zirconium in amount of 8-9% is applied on carrier. Due to developed surface, the claimed catalyst is efficient when hydrating compounds of various classes, and has high mechanical strength, which eliminates its abrasion in the process of exploitation.
EFFECT: obtaining catalyst efficient when hydrating compounds of various classes, and having high mechanical strength, which eliminates its abrasion in the process of exploitation.
