- 論文の詳細を見る
Catalytic hydrogenation of calcium D-xylo-5-hexulosonate (5-keto-D-gluconate) has been investigated on transition metal catalysts with special interest in the selective formation of calcium L-idonate. The reaction completed usually within several hours under 20-100 kg/cm^2 hydrogen pressures at 80°. Initial rates on a Raney nickel catalyst were represented by dC/dt=k'P_H_2^<0.5> where C is the degree of conversion. Nickel, ruthenium and palladium gave rise to more L-idonate especially when prepared from their salts by treating with sodium borohydride. For example, 73% of the hydrogenated products was L-idonate on a "boron-modified-palladium"catalyst.
