Abstract—The values of the hydrogen content in Raney nickel and in a porous nickel catalyst are found, and
the heats of hydrogenation of organic reagents both by gas-phase hydrogen and hydrogen adsorbed at the cat-
alyst surface are determined in aqueous solutions of sodium hydroxide and in dimethylformamide–water binary
solvents. By-side processes involving residual aluminum of Raney nickel are shown to influence significantly
the results of the determination of adsorbed hydrogen amounts and the heat effects of liquid-phase reactions on
skeleton catalysts.
