Hydrogenation of the acetylacetonates of Ni, Co, Cu, and Zn at atmospheric pressure and at 100 atm both on Ni and on NiM proceeded at a lower rate than the hydrogenation of pure acetylacetone. The rate of hydrogenation grew along the series of acetylacetonates Co < Zn ≤ Ni < Cu (Ni) and Co < Zn ≤ Cu < Ni (NiM).

Catalysts, prepared on silica gels that exhibit weak adsorption toward the molding compound, display selectivity during catalytic reaction.

The catalytic activity of sorskaya molybdenum ore was investigated with respect to the dehydration reaction, and it was found that the dehydrating ability of the ore depends upon the presence of molybdenum in it.

Certain chelate compounds, containing nickel and zinc, can serve as chemical models of alcohol dehydrogenase in the dehydrogenation of ethyl alcohol.

The refractometric method has been used to measure the cyclohexane-benzene equilibrium.

A general method was developed for preparing specific formed silica gels by introducing into the prepared gel a forming substance, and it is suitable for introducing substances that are insoluble in aqueous solutions.

Silica gel is a catalyst for the polycondensation of aminoacids.

Partial resolution of racemic hydrocarbons into their antipodes was effected by introduction of seed crystals of a clathrate compound of the optically active hydrocarbon.

The free radical 2,2-diphenyl-1-picrylhydrazyl undergoes stagewise hydrogenation over a rhodium catalyst. At first hydrogen adds at the free valence; this reaction is of zero order.
